Preamble
Dear Reader,
The TUM Department of Mechanical
Engineering is today one of the most
successful faculties of its kind worldwide.
This is demonstrated through all relevant
university rankings. It is placed in first or
second place within Germany and within
the ‘Champions League’ worldwide (c.f.
p. 27).
At the same time, the department is also
proud of its long and prestigious history;
founded in 1868 as the core of the former
Polytechnical School in the context of the
industrialization of Bavaria it was home to
and school of many renowned scientists.
In 2015, a ‘family tree’ of the department
was drawn up, which you can find as an
appendix to this report and in the ‘Magistrale’, the center of the main building of
the department.
In recent years, students, staff and
faculty of the department have become
much more diverse: in 2015, 21% of the
students came from abroad (+75% since
2011); 16% of scientific staff are female
(+42% since 2011); and 12% of the professors have an international background
(+100% since 2011).
In 2015, the success of the department
allowed us to attract Prof. Marburg (from
the University of the Armed Forces, Neubiberg) for the newly founded Institute of
Vibroacoustics of Vehicles and Machines.
In addition, Dr. Tropschuh, in charge of
Corporate Responsibility and Politics at
AUDI AG in Ingolstadt, was appointed as
honorary professor (c.f. p. 18).
Despite its long history, one aspect of the
TUM Department of Mechnical Engineering has remained constant throughout
the years; the department covers a very
large range of topics, both in teaching
and research: from the design of efficient
gears to studies on the usability of driver
assistance systems; from the description
of microfluidic systems to the optimization
6
Preamble
of production systems. Despite very
diverse approaches, the common goal is
to find technical solutions for the challenges faced by society:
n Climate Change and Shortage of
Resources
We work on new mobility concepts,
production processes, which are
highly energy and material efficient,
development and usage scenarios for
novel, ultra light and strong materials
as well as both the development of
highly efficient combustion plants and
renewable energies.
n Demographic Change
We study usage habits and develop
robots and assistance systems e.g. for
car and production environments as
well as medical devices and support
systems for the elderly.
n Urbanization
Approximately a quarter of the scien
tific staff works on projects related
to safe and efficient ground mobility,
now to a large extent focused on the
development of small vehicles with
very low fuel consumption or new types
of propulsion units, and possible new
types of ownership (car sharing, etc.).
With this brochure, we present an overview of the research at the department’s
institutes. We hope that it helps our
partners in academia and industry to find
experts for their issues, prospective students and junior researchers to identify the
supervisor that suits best her/his interests
and – last but not least – ourselves, the
colleagues and partners of this department, to inform themselves even better
about our research and teaching activities.
Prof. Dr. Tim C. Lüth, Dean
TUM Department of Mechanical Engineering
The Department of Mechanical Engineering of the Technical University of Munich
has stood for engineering excellence since
1868. It was founded amongst others by
the pioneer of refrigeration Carl von Linde
and the well-known mathematician and
materials scientist Johann Bauschinger.
It has been the workplace of famous university teachers such as Gustav Niemann,
author of the most important authoritative
work on mechanical engineering science,
the mechanical engineer August Föppl
and the thermodynamics researcher
Wilhelm Nußelt. The lectures given by Carl
von Linde inspired Rudolf Diesel to make
his groundbreaking inventions. Other
important students of the faculty were the
aircraft designers Claude Dornier and Willy
Messerschmidt.
Today, the Department of Mechanical
Engineering is one of the most successful
engineering faculties of the world. Leading
international surveys rank the TUM
in the world’s top group. This success is
primarily a result of published scientific
excellence, based on a balanced mix of
publicly funded projects and industrial
cooperation. The department benefits
from a highly innovative environment in
a prestigious university and the Garching
campus, one of the largest and most modern research centers in Europe, as well
as from powerful partners in industry with
their headquarters or research centers
in and around Munich. Young talented
people form the core of the Technical
University of Munich. Integrated into an
environment of experienced scientific
personalities, they are supported to
develop their performance and individual
strengths.
The educational objectives are expertise,
judgment and responsibility. In addition
to technical sovereignty and entrepreneurial courage, modern engineers are
also expected to achieve in mental and
emotional creativity, cultural sensibility
and social skills are as important, which
is an important cornerstone of the training
at the department (c.f. 50 and 51). Today,
about 5000 students are enrolled at the
Department of Mechanical Engineering;
more than one-fifth are international
students from 32 countries.

Department Board of Management
The Department of Mechanical Engineering is headed
by the Dean, two Vice Deans and the Dean of Studies,
elected by the faculty of the department every three years.
In order to facilitate communication and to put decisions
onto a broader base, the current Dean, Prof. Tim Lueth,
established a Department Board of Management in 2014,
comprising the deans and representatives of groups of
professors, each assigned with a specific portfolio of
responsibilities. The Department Board of Management
acts as an advisor to the Dean; the responsibility of the
Departmental Board (‘Fakultätsrat’) regarding formal
academic matters remains untouched.

Central Services
With about 5000 students, over 40 professors and well over 1000 employees, the
is of a size comparable to many universities. Even though most administrative
tasks, including project management and
accounting, are handled by the institutes,
many responsibilities are allocated to the
Dean of the department. This includes
responsibility for the resources allocated
to the department as well as student
services.
Increasingly, it is expected that departments follow up on the activities of their
members, actively shape their teaching
and research environment and develop
their own strategy, especially with
regard to department recruitment. All
this happens in an environment, where
resources are allocated more on the basis
of achievement and vision, and thus less
evenly distributed. Both TUM and the
profit from these developments, even
though they necessarily create administrative overheads.

In addition, examinations have to be processed and students expect professional
advice on very diverse topics.
In the last few years, two training centers
for undergraduate and postgraduate
students have been created, focusing on
topics not directly linked to the research
activities of the department’s institutes.
Through the ‘Center of Key Competences’
and the ‘Graduate Center’, the department
can now directly address the majority of
its members and, for example, implement
courses on good scientific practice.
In previous years, these services were
simply added to those of the classical
Dean’s office, creating a structure that
was increasingly difficult to manage, and
responsibilities were not always clear.
In order to better coordinate central
departmental services, Dr. von Feilitzsch
and Dr. Wagner coordinate these activities
and six units have been formed, reporting
directly to the Dean, in addition to a
personal assistant.

Honours Awarded During the Department Day
Honorary Doctorate
16
During the Department Day, Herbert
Kraibühler, former technical director of
Arburg GmbH + Co KG, was awarded the
honorary doctorate of the department.
The President of the TUM, Prof. Wolfgang
A. Herrmann, pointed out his remarkable
achievements and ideas in the research
and development of innovative plastic
processing and additive manufacturing
machinery.
He also proved to be a visionary in the
field of additive manufacturing. His
company cooperated over many years in
research projects with the TUM, examining fundamental issues from polymers
and dispensing procedures through to
optimal filling strategies. The result was an
innovative system for industrial additive
manufacture that can offer much more
than simple 3-D printers.
One of his great achievements is the
further development of injection molding.
He accelerated the integration of injection
molding technology in manufacturing
cells. He thereby optimised production
methods and anticipated the development
which we now know as Industry 4.0. In
addition Herbert Kraibühler recognised
early that the interaction between man
and machine would play a central role
in modern production. The result was
the development of innovative machine
control systems which make is possible
to control the increasingly more complex
injection molding processes.
Prof. Tim Lüth, Dean of the Department
of Mechanical Engineering, described
the collaborative work as ‘an exemplary
co-operation between an innovative,
family-run company and a university of
technical excellence’.

Appointments
In 2015, two new professors were
appointed at the TUM Department of
Mechanical Engineering:
Prof. Dr.-Ing.
Steffen Marburg
In recent years, the Gerhard Zeidler
Research Foundation has endowed the
‘Institute of Vibroacoustics of Vehicles and
Machines’ at the department. The foundation was established by Gerhard and
Ellen Zeidler with the mission, amongst
others, to advance engineering sciences,
especially with respect to the reduction of
emissions.
The aim is to enhance the physical
understanding of the emergence and distribution of air-borne and structure-borne
sound in order to deduce methods of
manipulation and reduction. Research
and teaching involve physical principles of
vibroacoustics, numerical simulations and
experimental investigations.
Prof. Dr.-Ing.
Peter Tropschuh
18
Appointments
In this context, in July 2015, Prof.
Dr.-Ing. Steffen Marburg (b. 1965) was
appointed to the newly founded institute.
His research interests encompass the
development and application of numerical methods for vibroacoustics and
aeroacoustics, the experimentally-based
virtual prototyping of complex models in
combination with parameter identification, the consideration and identification
of parameter variations and structural
acoustic optimization. The applications
are manifold and include automotive
parts, ships, electric tools and musical
instruments. Marburg graduated from
TU Dresden where he was awarded a
doctoral degree in 1998. Subsequently he
became a junior professor for Structural
Acoustic Optimization/Boundary Element
Methods in 2004. In 2010, he moved to
the University of the Federal Armed Forces
in Munich and became a full professor for
Technical Dynamics. Marburg is associate
editor of the peer-reviewed journal Acta
Acustica united with Acustica, editor of
the Journal of Computational Acoustics
and chair of TC Computational Acoustics
of the European Acoustics Association.
Hon.Prof. Dr.-Ing.
Peter Tropschuh
Dr.-Ing. Peter Tropschuh (b. 1958) was
appointed honorary professor for Developments in Automotive Engineering at the
Institute of Automotive Engineering. Prof.
Tropschuh studied at TUM and graduated
with a degree in Mechanical Engineering
in 1982. He received a doctorate for his
work on ‘Computer supported design
using knowledge-based systems’ under
the supervision of Prof. Ehrlenspiel at the
Institute of Engineering Design in 1988.
In the same year, Prof. Tropschuh started
working for AUDI AG in Ingolstadt. Over
the years he held various positions in
the field of development, including being
an assistant to the Director of Technical
Development and head of the General
Secretariat, the Product Strategy Committee, Advanced Engineering and AUDI AG‘s
Research Partnership Program. Between
2006 and 2012 Prof. Tropschuh was
responsible for Volkswagen’s ‘AutoUni’ in
Wolfsburg. Since July 2011 he has been
in charge of Corporate Responsibility and
Politics at AUDI AG in Ingolstadt. He has
held lectures on the ‘Trends and developments in automotive engineering’ since
winter semester 2007-08.
Research
At the TUM Department of Mechanical
Engineering, the institutes typically address
the whole value chain from scientific
foundations up to application scenarios.
The large size of the institutes allows them
to build up interdisciplinary teams.
The competitiveness of research is hard to
quantify. Typical indicators are third-party
funds and the number of publications.
Third-party funds
Third-party funds indicate that public bodies, such as the European Commission,
ministries and the DFG, or private entities
such as industry and foundations trust in
the competence and competitiveness of
research performed at the department.
During the last decade, third-party
funds at the department almost tripled.
This compares to a 52% increase of all
research funding at German universities
from 9.2 bil. (Mrd) Euros to 14.0 bil. (Mrd)
Euros between 2005 and 2012 (most
recent data available) – 120% at the TUM
during the same period of time.

Selected Highlights
Impression of experiments on brain-controlled flight
Imagine if airplanes were not controlled
manually but with the help of so-called
Brain Machine Interfaces that interpret
the pilot’s brain activity. Pilots would have
their hands free and physically disabled
people could fly. The goal of the research
project BRAINFLIGHT, a cooperation
between TEKEVER, the Champalimaud
Foundation, Eagle Science and the
Technische Universität München, was to
assess the performance of this concept.
Flight control algorithms developed at
TUM’s Institute of Flight System Dynamics
enabled some pilots to successfully
accomplish several tasks, including a
landing approach in bad visibility. The
experiments attracted international attention from experts and the media.
Funded by the European Community’s
Seventh Framework Programme (FP7)

New ERC Advanced Grant Awarded
n Prof. Nikolaus Adams, Chair of Aerodynamics and Fluid Mechanics, has
received an ERC Advanced Grant for his project ‘NANOSHOCK – Manufacturing Shock Interactions for Innovative Nanoscale Processes’.
Numerical simulation of a shock interaction with a
droplet: pressure and drop surface of a water drop in
air hit by a supersonic shockwave (Ma = 3).
The flow of liquids or gases is fundamental
to most technical applications and natural
phenomena. Among the most intriguing
fluid dynamics events are shock waves,
discontinuities in the macroscopic fluid
state that can lead to extreme temperatures, pressures and concentrations of
energy, which can be perceived, e.g. as
supersonic boom of an aircraft or as originating from an explosion. The violence
and yet the spatial localization of shockwaves presents us with a unique potential
for in situ control of fluid processes with
surgical precision. Applications range from
kidney-stone lithotripsy and drug delivery
to advanced aircraft design. How c an
this potential be leveraged/harnessed?
What mechanisms and inherent properties
allow the formation and control of shocks
in complex environments such as living
organisms? How can shocks be generated
in situ and targeted with high precision
for drug delivery while minimizing side
effects? What is the potential of reactive/
fluidic-process steering by shock-interaction manufacturing?
The objective is to answer these questions using state of the art computational
methods, supported by benchmark quality
experiments. Computations are based
on advanced multi-resolution methods
for multi-physics problems. Uncertainty
quantification is employed to derive robust
flow and shock-dynamic field designs.
Paradigms and efficient computational
tools are delivered to the scientific and
engineering community.
Prof. Nikolaus Adams has been Chair of
Aerodynamics and Fluid Mechanics at
the TUM since 2004. Adams was elected
as Fellow of the American Physical
Society for his work on computational
flow modeling in 2011. Jointly with a team
of scientists from ETH Zurich, Lawrence
Livermore National Laboratories and IBM,
Adams received the 2013 Gordon Bell
Prize for the largest and most efficient flow
simulation.

A generic satellite with a large reflector
Laboratory model for thermo-mechanical and electrical
test
Due to the size of such reflectors of 8 to
15 meters in diameter, they have to be
densely stowed for launch but precisely
deployed in orbit. They have to keep their
predominantly parabolic reflecting shape
within possibly µm-accuracy even under
extreme temperature variations from
+120°C down to -170°C. For that purpose,
CFRP foldable structures are combined
supporting reflecting surfaces composed
of a new type of composite material based
on carbon-fiber reinforced space compatible silicones (CFRS), i.e. a reinforced
‘rubber’. This allows dense stowage
and at the same time high accuracy and
stability in orbit. Appropriate material and
design concepts have been developed
under ESA contracts. Simulations and
hardware tests with scaled laboratory
models have now resulted in a technology
readiness level which allowed ESA to give
their go-ahead for verification tests of real
scale demonstrators.
Variations of such reinforced flexible
polymers also establish a basis for shape
morphing structures which adapt their
(outer) shape to achieve, for example,
the best aerodynamic efficiency and also
reduce radiated noise for aircraft wings
and engine inlets.

Speed2E powertrain layout
Speed2E is a collaborative project,
funded by the Federal Ministry of Economics and Energy (BMWi) and assisted
by the Research Association for Drive
Technology e. V. (FVA). The goal of this
project is to design and investigate an
electro-mechanical high-speed powertrain. It consists of two high-speed electric
engines with up to 30,000 rpm and a
gearbox consisting of two parallel partial
transmissions. One of these is designed
to be shiftable. The switching operation of
the electrically synchronized claw clutch
can be carried out by the two power paths
and the overload capacity of the engines
without interrupting traction.
By tripling today’s conventional engine
speeds of about 10,000 rpm, the volume
and mass of the engine can be cut approximately in half compared to today’s standards and the engine costs can be reduced
by about 30%. In theory, the power density,
efficiency and cost-effectiveness of electrified automotive powertrains can therefore
be increased significantly.

Condensation on a horizontal low-finned tube made of stainless steel. The small fins provide an enlarged surface for
heat transfer and enhance drainage of the condensate.
Experiments carried out at the Institute of
Plant and Process Technology showed a
high potential for use of low-finned tubes
for condensation in chemical processes.
Due to an increased surface for heat
transfer and improved fluid dynamic
characteristics of condensate flow, such
structured tubes can improve significantly
the efficiency of heat exchangers in
chemical plants. The outer heat transfer
coefficient of those tubes can be nine
times as high as for a comparable conventional plain tube.
The condensation of different pure
solvents and mixtures on horizontal lowfinned tubes made of different materials
was investigated. Alongside, a model was
developed with adaption of the experimental results, which allows dimensioning
of new improved heat exchangers for
condensation with higher efficiency.

n A sustainable energy supply is one of the essential requirements for
the future of our society. The goals of reducing CO2 emissions, achieving
cost effectiveness and societal acceptance make for a field fraught with
controversy.
The Department of Mechanical Engineering
has been a hothouse of research in energy
technology and thermodynamics ever since
the days of Carl von Linde and Wilhelm
Nußelt. The department has a particularly
excellent reputation in the areas of combustion technology and the development of
very efficient power stations. Our research
and teaching portfolio in renewable energy
has been expanded considerably in recent
years e.g. through the new Institute of
Wind Energy, although institutes covering
biomass, geothermal and solar energy have
existed for even longer.

Energy Valley Bavaria – Flexible Power Stations
The ‘Energy Valley Bavaria’ project consists of an interdisciplinary team investigating the effects of the energy revolution
on generation systems and electricity
grids. Investigative research is carried out
at the Institute of Thermodynamics on
increasing the flexibility of gas turbines
and analysis is carried out at the Institute
of Energy Systems on the dynamic behavior of steam generators. The results form
the basis of dynamic process simulations
which illustrate all the processes at work
in power stations.

Holistic Design of Wind Turbines
The Institute of Wind Energy develops
versatile design tools for wind generators.
Designing a wind generator should result
in generation costs being minimised.
However, this presents a very complex
engineering challenge requiring many
34
input parameters to be optimised e.g. efficiency, material and production costs for
all components, assembly costs as well as
operation and maintenance. Several other
general conditions must likewise be taken
into account.
Materials
n Materials make it possible to determine the manufacture of constituent
parts, transmit forces, determine the efficiency levels of machines and the
compatibility of medical implants. All three major materials categories,
polymers/plastics, metals and ceramics, as well as those derived from
them, e.g. carbon composites and other composite materials, play a
significant role in research and teaching at the department.
Key research areas include ultra-precise
antennae which can be used in space
for satellite navigation, manufacturing
medical components in sterile environments for use in the human body or the
automated manufacture of load-bearing
vehicle or aircraft parts. The Institute
for Materials Research and Testing in
Mechanical Engineering (part of the
Bavarian government) is another highlight
which illustrates how our wide ranging
material analyses enable deep insights
into all solid materials.

FORCiM3A
CRP is regarded as the ‘material of the
future’ which has so far led to innovations
spanning many sectors. However, one
area in which CRP has not yet found a
foothold is machine and factory construction. Whilst some successful combinations
of steel and carbon have been achieved
in industry, simply replacing metal with
carbon is not possible. Surmounting this
hurdle will therefore remain at the forefront
of research and development work undertaken by FORCiM3A. Hybrid joining techniques i.e. the combination of metal and
CRP is a requirement for thorough integration into the world of steel construction
and with that the secure joining in all
relevant geometrical configurations and
mechanical load scenarios. The advantage
of CRP components, other than their light
weight and increased strength, is that they
may last longer and be even more precise.
This is due to their higher material fatigue
resistance when compared to metals. The
tasks of FORCiM3A include designing the
relevant CRP compatible components
(drive shaft, clutch, underlying structure,
spring elements), designing the composite
CRP-metal material used for the components and checking its stability against
outside influences during operation e.g.
temperature, aggressive media or frequent
changes in load.

First-Wall Materials for Fusion Reactors
In magnetically confined fusion plasma,
the hot plasma core is largely separated from the first wall. Nevertheless
high-energy particles can escape from
the confined plasma and collide with the
surrounding wall. In this way, electromagnetic radiation from the plasma reaches
the wall material. In the case of burning
fusion plasma, the neutrons produced
can enter the wall material and alter its
characteristics through atomic shift and
conversion reactions.
In today’s fusion plants, such reactions
are counteracted with modern high-per-
formance materials. The research work,
being carried out at the Max Planck Institute, serves to examine more deeply the
complex interaction processes between
plasma and wall materials and then,
based on this knowledge, to develop new
materials with improved characteristics
which can be used for wall components
that may be subject to plasma radiation.

PolyTol
Plastics/polymer processing in Germany
is cost-effective for highly complex and
engineered processes. The decisive
quality characteristics in injection molding
are, in particular for medical products, the
early prediction and maintenance of close
tolerances for the components being
produced. Influencing factors extend from
molded-part construction and simulation
through injection molding tools and their
manufacture to the choice of polymers
and the appropriate injection molding
machine technology.
The PolyTol project will develop a comprehensive understanding of the factors influ-
encing the tolerances of injection-molded
components. The most important factors
in the development and manufacturing
chain will be taken into account and ways
of predicting the required maximum target
values will be developed.

RapidNAM
An average of one in 500 new-born babies
in Europe exhibits a cleft lip and palate.
With nasoalveolar molding (NAM), the
alveolar ridges can be brought closer
together using hand-made plates and
nasal stents which improve the shape
of the typically flattened nostrils. In this
manner, a severe cleft deformity can be
minimised and subsequent surgery is
simpler and the number of operations can
be reduced.
The manufacture by hand of NAM plates
and stents used until now required great
experience and was very time consuming,
not only for the medical staff but also for
the young patients and their parents. The
RapidNAM project intends to produce NAM
38
appliances automatically and in advance,
based on an initial jaw and nose cast, using
digital planning and a generative production method. The highest priority is to

Engineering since its inception.
For a long time, special emphasis has been
placed on integrating enhancements into
the entire process chain, from the design
phase to the customer, rather than considering individual stages in isolation. Closely
related to this are fundamental research
and application, such as the question of
how to simulate and suppress oscillations
in production machinery, how to implement
models for optimization of the design and

to reduce the loads acting on the human
body. At the same time, the working
conditions of manual handling can be
improved by such a system and this
possibility ensures injury-free work. These
advantages can be combined in an ergonomic body-worn lifting aid. In September
2013, the Institute of Ergonomics at the

Students’ Exchange
TUM students are offered several possibilities for spending some part of their studies
abroad – varying in region, duration and
educational goal. Within the framework of
the European ERASMUS+ program and
TUM’s worldwide TUMexchange-program,
students have the possibility to study one or
two semesters at one of TUM’s more than
430 partner universities. Moreover TUM
has signed more than 50 double degree
agreements worldwide, targeting students
with excellent academic performance who
are interested in doing an additional degree.
Tuition fees are waived for double degree
students as well as for students going
Incoming Exchange Students
In addition to recruiting an increasing
number of international full-time students,
the department successfully attracts
an increasing number of international
exchange students – both from within
Europe and worldwide. In winter 2015-16,
exchange students from 33 nations are
studying at the Department of Mechanical
Engineering.3
In 2014-15 almost 22% of the incoming
exchange students of TUM have been
enrolled at the Department of Mechanical
Engineering and another 47 students have
registered as full-time M.Sc. students
within the framework of the TIME double
degree programs.4

Outgoing Exchange Students
The Department of Mechanical Engineering
is not only aiming at increasing its international student body but also pursues
the goal to raise the mobility of its own
students. With the objective of being able
to offer every student the opportunity to
spend at least one semester abroad, the
department has signed 77 ERASMUS+
agreements with 94 schools in 23 European countries. Most of the department’s
partner institutions are in France (13), Spain
(13), Italy (8), the UK (7) and Sweden (5).
After a severe drop in the mobility rate in
2012-13 – most likely due to the transition
to the B.Sc./M.Sc. system some years
before – the numbers of students going
abroad has been continually increasing
since 2007-08 accounting for about 15%
of all TUM outgoing students.5

The Department of Mechanical Engineering decided to review the curriculum of its
Bachelor’s degree, comparing it with other
leading technical universities in Germany
and world-wide. As a first step, the
amount of teaching load (in terms of ECTS
credit points) was assumed to indicate
the priority given to the various aspects,
such as mathematics, mechanics, natural
sciences or design and construction.
To complement this external view, the
Bachelor of Engineering Science offered at
the Munich School of Engineering (MSE)
should also be regarded.
In general, the teaching load of the modules varies amongst German universities
by about only 10 ECTS (during the B.Sc.
program with 180 ECTS in total). Teaching
load at the TUM Department of Mechanical
Engineering is below average in mathe
matics and automatic control, above
average in computer science and business
administration, which is not addressed at
all in many cases. Mostly, requirements of

the program at the department meet the
recommendations of the ‘Fakultätentag
für Maschinenbau und Verfahrenstechnik’
(FTMV), in contrast to the MSE curriculum,
which – intentionally – contains significantly less machine design and electrical
engineering than recommended, and,
in exchange, well more than average
computer and natural sciences (see upper
diagram below).
Compared to universities in Europe (KTH
Stockholm, ETH Zürich, TU Delft, DTU
Kopenhagen, Politecnico di Milano) and
overseas (MIT, UC Berkeley, Beijing Institute of Technology, NTU Singapore, Seoul
National University), teaching load in the
same fields varies much more significantly
in comparison with German universities.
Most foreign universities emphasize
mathematics and natural sciences to a significantly greater degree, whereas teaching
load in engineering mechanics and machine
design tends to be – partially significantly –
lower (see lower figure below).

Gender Equality at the Department of Mechanical Engineering
About 10% of the doctoral candidates
at the TUM and in the Department of
Mechanical Engineering have children.
This information resulted from a survey
conducted with TUM doctoral candidates
in 2013. Regarding all TUM employees,
the percentage is certainly higher. Moreover the survey showed that more than
70% of the doctoral candidates with children feel that work on their doctoral thesis
and family life is mostly reconcilable.
How does the Department of Mechanical
Engineering support the reconciliation of
family life and work and study?
The Department of Mechanical Engineering offers a child and family room to
students, staff and guests. Parents and
temporary caregivers can use the room
with their children. Expectant mothers
are also welcome to take a rest. The
room provides space not only for playing,
eating, resting and changing nappies, but
also for working. It is therefore equipped
with a comfortable seating area, a working
area, playing corner, change table, a baby
food warmer, wash basin, microwave oven
and toys.
Babysitters can be organized via a service
provided at the TUM – especially for
evening events outside the opening hours
of childcare facilities. The department reimburses babysitter costs for staff participating in departmental events outside working
hours. More information on the child and
family room and the babysitter service can
be obtained at the gender equality office
(gleichstellungsbuero@mw.tum.de)
Another offer of the Department of
Mechanical Engineering is the payment
of a birth bonus to the department’s
institutes; the institutes receive €2500 per
expectant mother and €2500 for each
new father or mother at the institute. The
birth bonus aims to be active support in
reconciling of work and family. Possible
investments that can be made with the
bonus are the purchase of light laptops,
equipment for a home office or the
payment of student assistants to support
expectant mothers to conduct experimentation. This enables parents to be more
flexible if they have to take care of their
child during working hours. Expectant
mothers are supported in continuing their
work despite restrictions during pregnancy
and returning to work after maternity
leave.
To improve facilities for the whole female
staff, the Department of Mechanical Engineering is currently equipping six more
toilet and wash areas at the faculty with
showers for women. Consequently, each
wing of the building will be equipped with
showers for women. They can then more
easily take a shower after sport activities
or business trips.

Graduate Center Mechanical Engineering
The Graduate Center Mechanical Engineering was founded in 2009 as part of
the TUM Graduate School. Since the
beginning of 2014, participation was an
integral part of all doctorates. It provides
training courses specifically oriented
toward the needs of engineers, promotes
networking of the doctoral candidates
within the faculty and beyond. It also helps
the institutes to maintain highest scientific
standards. This highly innovative program
has been awarded the Best Practice
Award of acatech, the National Academy
of Science and Engineering.
In 2013 and 2014, the Graduate Center
Mechanical Engineering focused on the
enhancement of the doctoral studies. The
implementation includes some mandatory
and optional modules.
In addition to the mandatory basic pro
gram, the TUM Graduate School encourages doctoral candidates to undertake
a research period abroad to increase
international networking. The TUM GS
therefore provides financial support. It also
offers professional support in the submission of publications.
The Graduate Center Mechanical Engineering additionally provides an Initiative
Fund as financial support for doctoral
candidates e.g. for networking and internationalization. Furthermore the Graduate
Center Mechanical Engineering offers
several optional qualification programs
that support doctoral students in their
transferable skills, provides networks and
career orientation.
In 2015 the Graduate Center Mechanical
Engineering provided around 35 different
subject-specific and soft-skill workshops
for doctoral candidates.
To keep up the supervision quality in the
department the Graduate Center Mechanical Engineering started a doctoral survey.
Participants were asked about their
current situation and their suggestions for
the future. The results were satisfactory for
the faculty. Arrangements to optimize the
supervision quality were established and
implemented.
Center of Key Competences
Dr. Birgit
Spielmann
The Center of Key Competences offers
students at the Department of Mechanical
Engineering the opportunity to expand
their soft skills. These skills are becoming
increasingly important in the recruitment
process as well as in professional practice
itself. Our motivation is to train budding
engineers and to raise awareness of necessary professional skills to complement their
technical knowledge. Experience-based
learning and activity-oriented teaching
form the cornerstones of our educational
practices. We use a broad variety of teaching methods including practical tasks, role
plays, peer counseling and online training.
One of our key programs is the TUTOR
program which aims at expanding the
soft skills of Bachelor and senior students
using a two-step approach. In the first
step, senior students are trained by the
Center of Key Competences. They receive
intensive training in soft skills. Over several
days, the tutors learn how to organize
workshops and support team structures
as well as individuals. Then the tutors
assign small groups of Bachelor’s students. During their first year, the Bachelor
students are coached by senior students
who hold workshops and supervise their
team project. In the first semester, the
Bachelor students participate in workshops
on social topics, such as communication,
teamwork, presentation skills or motivation. In the summer semester, they can
demonstrate their team skills in project
work by developing a product. On the one
hand, the TUTOR program introduces the
basics of soft skills to Bachelor students.
On the other hand, senior students have
the opportunity to broaden their skills by
teaching and coaching their group.
Within the framework of the TUTOR
program, a new program has recently
been introduced; TUTOR FührungsKolleg.
Former tutors can participate in the tutoring
program once again, taking over additional
leading tasks in one of several departments
including recruitment, competition or public
relations. This new program gives them the
opportunity to further enhance their key
competences.
The Master students participate in the
Master Soft Skills Workshop Concept.
Each semester they can choose from
courses to strengthen their skills in three
areas of competences: methodical, social
and personal competence. Beyond the
ZSK provides Academic Writing courses to
all Master students.

Student Council
The Student Council Mechanical Engineering represents all students at the
department. With currently about 120
voluntary members it is one of the largest
student councils in Germany and is therefore organised in various different departments. During the yearly elections held in
line with the Bavarian Higher Education
Act, the department’s students elect the
student representatives, supported by
numerous co-workers, depending on the
current number of students enrolled at the
department.
The activities of the various departments
in 2015-16 were as follows:
52
Student Council
Event Department
The year was accompanied by events
arranged for the students and started with
the impressive ‘esp’ – with 5000 guests,
the biggest party in southern Germany
organized by students. During the winter
months, the nicely decorated Christmas
tree brought Christmas atmosphere into
the department. When the cold was gone
and summer started, the sports meeting
was the perfect event for inaugurating the
new sports field at the campus with space
for basketball, volleyball and football.
Coincidentally, some brand-new balls
were found in the rooms of the student
council and the matches could begin! For
the first time the student council additionally organized the 6 km Campus-Run
together with the TUM:Junge Akademie,
which was a great success. The council
is very proud of the blood donation event,
which from now on will take place regularly. Several other events delighted the
students such as a pub crawl, a festival
with a barbecue or a poker competition.
Magazine of the Student Council
Higher Education Policy
In past years, as well as in 2015, the
student council published six issues of
its magazine, the ‘Reisswolf’. Each issue
consists of news from the student council
itself as well as reviews of excursions, for
example to Munich Airport or the neutron
source Heinz Maier-Leibnitz (FRM II) on
the Garching campus. Another highlight
were the car reviews written by the
students themselves. Furthermore, articles
from university groups contribute to every
issue. The ‘Lehrstuhlserie’ as part of
almost every issue introduces the department’s institutes to the readers. Another
part of our tasks is the ‘Klopapier’, which
provides entertainment on the toilets in
our building.
Together with the TUM Department of
Mechanical Engineering, the student
council worked on a few major projects
to improve teaching and the learning
environment. In the ‘Studienzuschusskommission’, more than 300 applications
were granted to advance the quality of
teaching. One perfect example of that will
be the new MATLAB online course which
is being developed by Dr. Karpfinger in
collaboration with the student council.
As a major infrastructural improvement,
a common system to register for lab
courses was designed and is right now
being put into action. The student council
on its own would not be able to do that,
therefore a work group with participants
from the various different parties at the
TUM Department of Mechanical Engineering was formed and worked well together.
Writing about university policy does
almost always mean writing about study
and examination regulations as well. This
year, the student council was engaged
to keep the internship needed to enrol
for mechanical engineering as short as
possible. As a result, the workload stayed
at eight weeks before starting studies and
ten additional weeks within the Bachelor
studies.
Print Shop
As in previous years, the student-owned
print shop printed and sold all kinds of
lecture scripts. Thanks to the cooperation
of numerous institutes, it was able to print
the lecture notes of nearly 200 different
lectures, seminars and lab courses of the
department.
A special event for the print shop was
the purchase of a new thermal binding
machine in September which now
facilitates and accelerates the production
of the lecture notes a lot.
Freshman Department
International Department
As every year, the international department organized the buddy program,
beginning with an incoming event for the
international students of the summer term.
Beside regular bar evenings, the biggest
event in this summer was a dance ball for
the students (international and German) of
the Department of Mmechanical Enginee
ring. After the summer break, the winter
term started with a get-together of the
new incoming students even before the
lecture period. Furthermore, the welcome
event, regular bar evenings and a pubcrawl were continued. The highlight of this
term was a Christmas party including an
international buffet, drinks and more.
The student council cares for all the freshmen coming to the dDepartment. This
summer, for the first time, an orientation
week was organized, including a scavenger hunt in Munich, a Bavarian breakfast
with beer and veal sausages and a sport
event. In the first two days of the winter
term, the traditional event was organized
to give the freshmen all the information
they need at the beginning of their studies.

A highlight was that Prof. Adams received
an Advanced Grant from the European
Research Council for the Project NANOSHOCK – Manufacturing Shock Interactions for Innovative Nanoscale Processes
with funding of €2.4 million. The institute
contributed two technology projects to the
development of Bluecopter Demonstration
technologies, enabling environmentally
friendly short-range air transport.
Dr. Stefan Hickel, formerly Senior Lecturer
at the institute, was appointed as Chair of
Aerodynamics at TU Delft.
Cavitating Flows and Cavitation Erosion
Motivation and Objectives
We investigate liquid flows with partial
evaporation due to flow-induced local
pressure drops below vapor pressure,
known as cavitation. Cavitating flows play
an important role in injection systems of
diesel and Otto engines, in components of
spacecraft engines as well as in ship propulsion systems. Managing the complexity
of two-phase flows with phase transition
is challenging, and experimental investigations often cannot go beyond model
devices. In particular, violent collapses
of vapor bubbles and the resulting shock
waves need to be predicted and their
erosive mechanisms have to be clarified.
Approach to Solution
State of the art numerical procedures
and physical models for the simulation
of cavitating flows are developed. Fully
compressible approaches for complex
fluids, including liquid-vapor-gas mixtures
and a time resolution of nanoseconds,
are key factors for predictive simulations.
Fundamental research is funded by the
Deutsche Forschungsgemeinschaft and
the European Union. Applied research in
cooperation with automotive suppliers, the
European Space Agency and the Office of
Naval Research enables dissemination of
fundamental research into application.

Large Eddy Simulation of Complex Turbulent Flows
Scientific discovery through modeling
and predictive simulation requires numerical models and solution methods that
accurately represent and resolve relevant
flow physics and efficiently exploit modern
massively parallel supercomputers.
Adaptive flow simulation refers to highly
automated flow simulations which require
only a minimum of user interventions,
while delivering reliable results. This
includes methods for automatic mesh
adaptation as well as for the quantification
of uncertainties that result from model
approximations, initial data, or boundary
conditions. Adaptive DNS/LES requires
methods that couple numerical and
physical models on multiple scales in a
consistent way. For example, we have
developed sophisticated wall turbulence
models, which facilitate LES of engineering aerodynamic applications.

Particle Modeling of Fluid Dynamics
Despite their wide-spread use, typical particle methods, such as smoothed particle
hydrodynamics (SPH), for simulating fluid
dynamics cannot deal with realistic flow
parameters without numerical regularization that interferes with the underlying
physical model. SPH and their mesoscopic extension SDPD, are very attractive
numerical models for fluid flow of extreme
physical complexity.
SDPD simulation of elastic turbulence in a polymer
solution
We have developed SPH/SDPD approaches capable of modeling complex
63
microflows. In particular we have devised
a new SPH paradigm which enables SPH
to reach realistic flow parameters without
artificial regularization.

High-order Numerical Models for
Complex Fluid Dynamics and Interactions
Direct simulation of shock-liquiddrop interaction
Although high-order schemes have been
widely used in numerical simulation of
flow phenomena they face great challenges for achieving both high resolvability
of flow structures and high robustness for
coping with discontinuities and interface
interactions. The numerical modeling of
multi-phase flows must have the capability
to reproduce the evolution of fluidic interfaces which may become very complex
and produce small-size structures beyond
the resolvability of the computational grid.
Such under-resolved structures very often
lead to numerical instability and failure of
numerical simulation.
64
Based on our newly developed WENO
methodology, we design numerical
schemes with the ability to separate flow
structure according to their characteristic
length scales and to handle large scale
and small scale structure in physically
consistent ways. The developed numerical
schemes achieve very good resolvability
without compromising robustness. We
have developed a multi-scale method
to cope with under-resolved interface
structures. The core approach is a
so-called stimulus-response model which
measures the smoothness of the interface
and separates resolved and non-resolved
scales in a simple and efficient way.

Aircraft and Helicopter Aerodynamics
Performance enhancement and reduction
of emissions are key objectices within the
framework of the European ‘Flightpath
2050’. For the current research projects,
improving flow physics knowledge and
modeling are related to unsteady aerodynamics and aero-elasticity, turbulent
flows and active flow control. Special
emphasis is on the aerodynamic characteristics of highly maneuverable aircraft
and large transport aircraft as well as on
unconventional and UAV configurations.
Specific research activities in the field of
aircraft and helicopter aerodynamics deal
with means of drag reduction by shape
optimization, novel air intake solutions,
flow control using active devices, pulsed
blowing and plasma actuators and unconventional lift generating systems including
the fluid-structure interaction of flexible
adaptive wings.
The investigations are performed includ
ing both wind tunnel experiments and
numerical simulations. Commercial as
well as in-house codes are used, while
code development is mainly conducted in
the context of aeroelasticity and reduced
order models.

Laminar-turbulent Transition with Chemical
(Non-)Equilibrium in Hypersonic Boundary-layer Flows
Motivation
In hypersonic flows, the heat transfer differs up to an order of magnitude comparing laminar and turbulent boundary layers.
The prediction of the transition location on
blunt re-entry configurations aims at the
understanding of the underlying instability
mechanisms. The influence of the chemi-
Flow around a re-entry capsule

cal state of the boundary layer (equilibrium
or non-equilibrium) in these high-enthalpy
flows is the main focus.
Direct numerical simulations (DNS) are
conducted on national HPC facilities such
as SuperMUC and HLRS. Results show
that early stages of hypersonic transition
are not substantially affected by chemical
reactions. Simulations are currently under
way taking into account the surface
roughness and the noise which can lead
to transient growth of disturbances to
non-linear amplitudes where they can be
enhanced through the presence of the
chemical reactions.

Automotive Aerodynamics
Way to Solution
One approach to unsteady aerodynamics
is to analyze the dynamic behavior of the
flow field using dynamic mode decomposition (DMD). DMD is found to extract
useful information from the flow, when it
is applied to three dimensional velocity
vector fields. It is a method to extract
coherent structures by decomposing
the flow into dynamic modes. Analyzing
the turbulent structures and their origins
allows shape optimization leading to drag
reduction of the component or full car.

Motivation
Automotive aerodynamics deals with the
aerodynamic optimization of vehicles
driven by combustion engines or electrical
motors. Key objectives are drag reduction
and unsteady aerodynamics with its
influence on the driving stability and the
aerodynamic coefficients. With respect
to high drag reduction potential, the
wheel/wheelhouse region is dedicated to
systematic optimization.

Technological Foundations for the Design of Thermally
and Mechanically Highly Loaded Components of Future
Space Transportation Systems
The institute has the speaker role within
the DFG-SFB TRR40. Next-generation
space transportation systems will be
based on rocket propulsion systems
which deliver the best compromise be
tween development and production cost
and performance. The TRR40 focuses on
liquid rocket propulsion systems and their
integration into the space transportation
system.
Critical, thermally and mechanically highly
loaded components of such space transportation systems are the combustion
chamber, the nozzle, the aft body and the
cooling of the structure. These components offer the highest potential for the
efficiency increase of the entire system.
However, all components are in close and
direct interaction with each other. Optimization or the fundamentaly new design
of a single component directly affects all
other components.

New structural concepts – structural simulation and design optimization methods –
experimental structural and material investigations
n A highlight in 2015 was the finalization of the laboratory model of an
advanced large, precise and also structurally deployable space antenna
reflector, which is now under rigorous testing in the institute’s labs and at
ESA. Its concept has been derived and investigated in recent years from
design considerations, large scale mechanical-thermal-electrical simulations as well as special material developments and investigations.
For the scaled demonstrator of the
Sagitta advanced unmanned aerial
vehicle, the fiber composite structure
developed in cooperation with DLR
has been built and delivered for further
testing to the project coordinator Airbus.
It will be used as a flying testbed for
several advanced aerospace technologies contributed by different German
Universities and DLR.
The Sagitta Unmanned Aerial Vehicle
The advanced Sagitta unmanned aerial
vehicle (UAV) is a research and demonstrator project under the lead of Airbus DS
with contributions from several German
universities and DLR. This project combines different research studies specifically
relevant for such UAV together with
the full aircraft development process.
Its carbon fiber structure developed in
cooperation of LLB together with DLR
has been delivered to the project
coordinator Airbus, where further
advanced technical contributions from
several Universities and from DLR are
integrated for flight testing and demonstrations. Because of the relatively high
flight speed and advanced communication
and control methods, this testing will be
also quite challenging.

In addition to the demonstrator and flight
model structure, investigations have been
carried out by LLB on shape morphing
rear wing parts of this delta wing aircraft.
In-flight aerodynamics and agility shall be
further improved, while noise and radar
visibility shall be reduced. Like in other
cases of morphing structures, certain
highly flexible degrees of freedom are
generated to allow significant shape
changes while at the same time being
able to take significant flight loads.
Derived shape morphing parts achieve
their deformability in certain degrees of
freedom like in shear, while all the other
degrees of freedom like those for bending
are sufficiently stiff to take high loads and
also to satisfy e.g. aero-elastic requirements.

Large Space Antenna Reflectors
Generic space antenna reflector
Large space antenna reflectors are to be
used for communication, radio astronomy
and earth observation. Due to their size,
they have to be stowed for launch and
precisely deployed in orbit, where then
only little deviations from the ideal surface
shape are allowed even under extreme
temperature variations. After years of
investigations mainly funded by ESA,
LLB established a large laboratory model
which has been accepted by ESA for
further rigorous tests. Emphasis is put on
thermo-elastic behavior at higher and very
low temperatures (-170º C).

Shape Morphing Structures
While in operation, (aerospace) structures
more or less keep their shape. This then
means that their shape designed for
certain relevant but more or less fixed
‘design points’ loses its efficiency at other
conditions. This for example holds for
aircraft components and structures in their
flow fields, or for those in electromagnetic
fields for space antennas with radiated
electromagnetic beams patterns to be
modified. These are a quite challenging tasks, because on the one side high
loads or high shape precision have to be
taken or maintained, while on the other

side the significant shape changes call for
special mechanical flexibility also in order
to limit the required actuation effort. Proper concepts are identified via a synthesis
between design and material concepts
together with sophisticated simulation and
experimental steps. For example, special
material models have to be combined
with structural models allowing for large
geometrical deformations.
LLB is working in different potential
application fields for shape morphing
structures:
n Shape morphing rear aircraft wings or
wing trailing edges, which shall reduce
aerodynamic drag, noise and radar
visibility, like for Sagitta mentioned
above
n Shape morphing inlets of aircraft
propulsion systems, which adapt their
geometric shape to different operational conditions for takeoff, landing
and cruise. An increase of propulsion
efficiency and noise reduction shall
be achieved (see project MorphElle
described below).
n Shape morphing space antenna reflectors, where due to (drastic) change in
the shape of the reflecting surface the
radiated electromagnetic wave pattern
can be adapted to changing communication needs between different regions
of the earth.
In the EU project MorphElle on shape
morphing inlets of aircraft propulsion
systems, different European university
institutes, Bauhaus Luftfahrt (BHL) and
an industrial advisory committee have
investigated different concepts.
The basic goals for this are the further
improvement of efficiency by an even
more uniform airflow inside the inlet at
different flight conditions, where at the
same time radiated noise is to be reduced.
Derived from system requirements
established by BHL and air flow and noise
simulations carried out by KTH Stockholm, LLB together with University of
Bristol established, simulated and tested
design concepts in combination with new
types of materials. An important key is the
development of shape morphing skins.
They consist of special metal wire meshes
imbedded into an elastomer, thus allowing significant pneumatically actuated
shape changes via its low in-plane shear
stiffness. Different multi-scale simulation
and homogenization steps allowed modelbased optimization iteration loops to
achieve the required behavior. Different
materials and structural properties
have been determined by optimization
techniques such that under proper
pneumatic actuation the inlet goal shapes
determined from KTH are achieved in the
best possible way.
Representative sections of shape morphing inlets have been tested at University
of Bristol for preliminary concept validation and simulation-test correlations.

High Performance Mathematical
Design Optimization Methods
Structural design optimization techniques
based on mathematical optimization
algorithms have been researched and
extended in two directions:
n Computationally expensive system
models like in highly nonlinear dynamic
systems are treated by appropriate
simulation model reduction techniques.
For optimization, such reduced models
still have to keep their design or
optimization parameters e.g. related to
topology, geometry of materials. This
leads to parametrized reduced order
models, or P-ROMs
n The scope of applications has been
further broadened by inclusion of
verbal or qualitative knowledge, which
is transferred to numerical models via
soft-computing techniques based on
Interaction of structural mechanics, manufacturing effort and uncertainties in design
optimization
73
fuzzy methods. These models then
are added to the structural simulation
and optimization models to establish
comprehensive overall models.
to the arrangement and type of their
stiffeners needed for example to prevent
instability of the thin outer shell. Conventional structures with orthogonal arrangement of circular and longitudinal stiffeners
can be realized with even lower masses
if stiffeners are arranged in ‘geodesic’
topologies. This arrangement derived from
mathematical topology optimization tells
that a higher percentage of longitudinal
stiffeners in the top and bottom part of the
fuselage should be used, while a more +/45 degrees arrangement at the side parts
is preferable.
Structuring the solution process for combined structural and manufacturing effort optimization
Standard arrangement of stiffeners in a fuselage shell
Geodesic stiffener arrangement
derived by topology optimization
The latter leads to integrated structural
mechanics and manufacturing effort
models of components and structures
for the mathematically based design
optimization process. For consideration of
qualitative knowledge e.g. on manufacturing effort, ‘what if’-questions for assumed
parameter variations and their consequences on the effort are asked to specialists. From their qualitative replies like
‘increases a lot’ or ‘decreases slightly’,
numerical relationships between design
optimization parameters and relevant
output quantities like for manufacturing
effort are established. These then get part
of the overall optimization model together
e.g. with FEM for the structural mechanics
aspects.
In most of these cases, parallel computing
on multi-processor computers plays an
important role to keep computation time
or so called turn-around time within limits.
For example, aircraft fuselage shell structures have been investigated with respect
Modeling steps for C-fiber braided automotive frame section
74
Relative manufacturing effort (ME) before and after
combined structural-ME optimization
Such design optimization activities were
also investigated within the Spitzencluster
MAI Design to properly cover the interaction of manufacturing effort and structural
behavior under different operational
conditions. Car body frames consisting of
A-pillars and roof frame parts were used
as reference examples for C-fiber braiding
and C-fiber lamination manufacturing
processes. Again, mechanical simulation
models covered the behavior from microto macroscale, while the manufacturing
effort as function of different design parameters has been derived from interviews
of specialists and transferred to numerical
models via fuzzy methods. Optimization
algorithms modified geometric crosssection and fiber arrangement parameters
such that the manufacturing effort
(production time) e.g. for the braiding
process could be reduced by around 50%
with only marginal mass penalty. Comparison of results from frames manufactures
by braiding and lamination process
then also allow the selection of proper
manufacturing methods based on an even
more rational trade-off between structural
properties and manufacturing effort.
Hybrid Material Structures
Since a basic approach in lightweight
structures is to identify and put proper
materials to proper components and positions within a structure, several activities
have been carried out in this area also in
order to identify and reduce possible of
mismatches of the different materials. This
not only relates to their interfaces, but may
become also relevant on components and
structural level.
For example, many thermal cycles in
carbon fiber reinforced materials and parts
may lead to micro-cracks in the polymer,
especially so for cycling amplitudes in the
range of +100°C down to -150°C which is
typical for many structures in space. Due
to a softening effect of such micro-cracks,
the C-fiber gets even more dominant for
the overall properties of the composite.
This then results into a further decrease of
the coefficient of thermal expansion, which
could change from say -0.2 E-6 / °K down
to -1 E-6 / °K. Though still very small in
absolute terms, this large relative change
might become relevant for structural
thermo-elastic deformations and related
loss of geometric precision in orbit.
Steel fiber reinforced aluminum parts have
Simulated and tested behavior of steel ropes in aluminum base material relevant for crash
properties
been investigated in cooperation with
Institutes from KIT and TU Dortmund in
the SFB/TR10 on advanced manufacturing
processes for such materials. Since such
parts are mainly aimed for automotive
applications, investigations on crash
absorption have been finalized end of this
year. These investigations covered related
materials and components simulations
and experimental investigations. Results
showed the benefits of such reinforcements, which allow to control the crash
behavior.

To answer ergonomic questions regarding
vehicles often simplified mockups are
used. The modular ergonomic mockup
(short MEPS) is an automated versatile
version of such a test rig. Developed and
used by the Daimler AG it was donated
to the Institute of Ergonomics in 2013. A
group of five bachelor students, a graduated research assistant and the technical
personnel of the institute have moved and
build it up at the chair.
Using the modular ergonomic mockup
different vehicle geometries from sport

also research in production ergonomics.
The resulting approach of user-oriented
assistance has now been implemented in
the form of different prototypes, ranging
from a thumb support for workers in the
automotive production up to an exoskeleton for manual handling tasks.
cars up to trucks, as well as tram wagons
and new innovative concept of the
interior can be represented without big
constructive change at the mockup itself
and in relatively short time. The flexibility
is achieved on a modular construction
using so-called module wagons and a rail
system. Different module wagons exist for
different assembly components (e.g. car
body, steering wheel, seats, etc.) which
can be placed on the rail system variable.
A hydraulic lifting system allows to change
the wagons as needed.
The wagons are electrically controlled
by a LabView-based program in up to
4 degrees of freedom (3 translations and
1 rotation) according to the demand of
the assembly. This procedure permits the
high variability of the system.
Using the modular ergonomic mockup
a wide area of research topics can be
investigated:
n Digital human modeling

n Driving simulation
n Innovative interior concepts

Seat Test Dummy
Validation process of the dummy
(Reference: André Dietrich)
The evaluation of newly developed car
seats nowadays requires several studies
with numerous participants to be conducted. To decrease the number and effort of
aforementioned experiments and present
a simplified way for objective comfort
measurement, the Institute of Ergonomics
developed a silicone dummy that represents the pressure distribution of a 50th
percentile male on a car seat. While previously developed dummies focused on the
femoral and gluteal pressure distribution,
the presented dummy is extended with
a back to ensure discomfort evaluation
along the entire seating surface. The inside of the dummy consists of 3D-printed
parts resembling skeletal structures, which
are attached to an aluminum framework.
This allows the back to be bent in predefined joints for up to ±20 degrees. The
surrounding silicone is attached to the solid
parts in multiple layers, imitating different
kinds of tissue in human bodies. In future
studies the dummy will be used to measure its pressure distribution in different
seat concepts so that comparisons with
results of discomfort studies with human
participants can be made.

Thumb Protection – Thumb Support
Although automation of many processes
is increasing the greatest part of production tasks is still manual which leads
to high workloads on the human body.
Due to shorter cycle times and simplified
tasks, cycles are characterized through
high forces as well as high repetition
rates. Especially in areas like automotive
assembly, the whole upper limb of the
human body is stressed. In the case of
the hand, the thumb, for example, used
to push plugs into the bodywork of a car,
is exposed to high physical strain. Due to
this a functional assembly aid to support
the thumb was developed, with the
primary goals:
n keeping the thumb within a neutral joint
position
n transmitting the force from the fingertip
to the whole thumb
The thumb support is individually adjusted
and 3D printed. Results from nearly 100
interviews from workers testing the thumb
support showed a subjective load reduction for the thumb. Furthermore the effort
Application of the thumb support
(Reference: Christin Hölzel)
to insert plugs was minimized. Based on
this feedback, this first prototype will now
be improved. Although several improvements were implemented acceptance is
still limited due to limited usability when
gripping parts. Nevertheless the overall
feedback is positive. An evaluation of the

UR:BAN – a German Research Initiative
Focusing on the Challenges of Future Urban Traffic
Urban Space: user-oriented
assistance systems and network
management (Reference: www.
urban-online.org)
Over thirty partners, including automobile
and electronics manufacturers, suppliers,
communication technology and software
companies, as well as research institutes
and cities, have joined in the cooperative
project UR:BAN (German acronym for
Urban Space: User-oriented Assistance
systems and Network management) to
develop advanced driver assistance and
traffic management systems for cities.
The focus is on the human element in
all aspects of mobility and traffic. The
research objectives will be pursued in
three main thematic target areas:
n Cognitive assistance
n Networked traffic management
n Human factors in traffic.
The Institute of Ergonomics leads the
project ‘Human Factors in Traffic’ which is
thematically subdivided in the projects
n Urban driving
n Urban-specific HMI design
n Behavior and intention recognition
n Simulation and behavior modeling
nControllability
to work on the challenges of urban traffic
and foster the support of the driver in
concerns of a safer, more efficient and
less straining urban driving experience.
The initiative is funded by the Federal
ministry of Economics and Energy due to
the decision of the German Bundestag
and started in April 2012 for the duration
of 4 years.
Social Interaction in Synthetic Environments –
The Pedestrian Simulator
In the sub-project ‘Simulation and
Behavior Modeling’ of the research
initiative UR:BAN (www.urban-online.org)
the activities focus on the analysis and
corresponding descriptive modeling of the
behavior of road users and of their mutual
interactions. This modeling will be coordinated with the applications developed in
other UR:BAN projects. The focus here is
on the behavior of informed and assisted
drivers, taking into account in detail their
interactions with other vehicles (with/
without UR:BAN technology) as well as
with cyclists and pedestrians.
To enable the investigation of social
interaction between pedestrians and
drivers in urban scenarios, the Institute
80
The virtual pedestrian simulator
(Reference: Ulrich Benz/TUM)
of Ergonomics developed a pedestrian
simulator and linked it to the institute’s driving simulators. The pedestrian simulator
consists of a motion capture system, a
head-mounted display, a motion-suit and
the driving simulation software. Thus it is
possible for two (or more) participants,
using the driving simulator(s) and the
pedestrian simulator, to meet in the same
virtual world and adapt their behavior
corresponding to each other.
In several studies the empirical work
focused on the quantification of social
interaction (i.e. Lehsing, Kracke, Bengler,
2015), the validation and immersion
improvement of the pedestrian simulator.
The pedestrian simulator itself can be
used as a stand-alone experimental lab
or linked to a driving simulator to analyze,
for example, critical crossing situations,
the acceptance of future driver assistance
systems or the parametrization of autonomous driving cars.
Replacement of Mirrors in Trucks
In 2016 a change in regulation ECE R46
(devices for indirect vision in vehicles)
will allow camera monitor systems
(CMS) to replace mirrors. The according
requirements are based on ISO 16505.
The Institute of Ergonomics participated
on the draws of both documents. In a
project together with MAN Truck & Bus AG
a CMS prototype for trucks was realized.
The main focus was the optimization
of the image representation to human
perception:
In nature, an object is normally detected
in the peripheral field of view (mostly by
a change in optical flow) and can then
be focused by the line of sight (so called
foveal vision). Normal mirror systems
violate this principle. The driver has to
focus on the dedicated mirror to be able
to detect objects within it. With currently
six prescribed mirrors in truck, the task of
observing all fields of indirect vision simultaneously gets pretty complicated for the
driver, as foveal vision is not parallelizable.
In general new ways of image representation are possible by establishing CMS
Comparison of the CMS with
the current mirror system on the
passenger side: one single display
replaces three mirrors. The cyclist
is detected easily within the CMS
(Reference: Albert Zaindl)
in vehicles. The developed prototype
combines the mandatory fields of view
from the main, wide-angle and close proximity mirror to one single and consistent
image. With this CMS the driver can keep
track of the whole surroundings within one
glance. The driver is now able to detect
objects within the short range of the truck
easily and particularly even randomly by
peripheral vision. The system enables the
driver to overview happenings around the
truck more quickly and accurately which
is accompanied by an increase in safety
(Zaindl, 2015a; Zaindl, 2015b).
Cooperative Systems and User Friendly Automation
The research group Cooperative Systems
and Automation pursues a cross-domain
approach to address a variety of research
questions in the fields of vehicle automation, cooperation, robotics and aviation.
By introducing cross-functional design
paradigms for interaction and user
interfaces and developing methods and
metrics for measuring and inferring user
states, a human-centered holistic view
on multilevel automated and cooperative
systems is enabled. This holistic approach
also becomes apparent in interdisciplinary
projects like the sociotechnical project
ASHAD, where the Institute of Ergonomics, together with five other institutes
of the TUM, examines highly automated
driving from different perspectives, among
them ethics, economics, acceptance
and trust. The European Initial Training
81
project Ko-HAF aims to address driver
state in automated vehicles and its impact
on safety and comfort on motorways.
The consortium includes several German
OEMs and Tier 1 suppliers from the
automotive industry.
Cross domain approach consisting of automotive, aviation, and
robotics (Reference: Julia Fridgen,
Jonas Schmidtler)
Network HFAuto integrates driver state
monitoring with the design of human
machine interfaces integrating visual,
sound and haptic cues to achieve a safe
and acceptable driver interaction in highly
automated vehicles. The nationally funded
Projects
n ASHAD (automation and society –
highly automated driving)
n HFAuto – human factors of automate
driving
n SaMSys – safety management system
in aviation
n KobotAERGO – adaptive collaborative
robots as age-adjusted companion for
ergonomic and flexible material handling
n Ko-HAF – cooperative highly automated
driving
Usability and User Experience
The main focus of the research on
usability and user experience is the finding
and understanding of different factors
of human machine interface design and
their effects on usability and user experience. A basic requirement for consistent
communication and research is a confined
definition and differentiation of the terms
usability and user experience. It is the
foundation for fundamental research
which aims at identifying relevant factors
that can be adjusted to optimize human
machine interaction.
Main topics of the research on usability
and user experience at the Institute of
Ergonomics are interaction design for
touch screen devices, gesture interaction
for utility vehicles, and the digitalization of
workplaces.
Regarding gesture interaction, the aim
is to specify recommendations for an
ergonomic and usable application of
gesture control in utility vehicles. Since
an ergonomic and usable application of
gesture control is based on the identification and specification of suitable use
cases, meaningful gestures and appropriate gesture recognition technology, these
criteria are within the scope of current
research work.
82
Different hand postures which gestures used for
gesture interaction potentially can comprise (Reference: Michael Stecher)
The design of software for a traffic control
center is an example for the digitalization
of workplaces. The challenge is to prevent
information workload in critical situations,
and at the same time to not leave out
information, which is important for
monitoring.
The group contributes to a general
propagation of ergonomic product design
by taking part in standard publishing
committees (e.g. VDI 3850).

Process development, particle technology, filtration, and extraction
n The Bioseparation Engineering Group deals with different aspects of
the isolation and purification of biomolecules for the pharmaceutical or
chemical industry. We are focused on adsorption, filtration, and extraction
as separation methods as well as their integration into the production
process. In addition to the experimental approaches we use COMSOL
and COSMO-RS for modelling and simulation.
In 2015, we could finally claim that
bioseparation engineering is successfully
established as new research field at TU
München. As one of the highlights the first
PhD thesis in our group was finished with
the focus on antibody purification. The
development of new high selective stationary phases with a high binding capacity
yields an increased separation productivity
of antibodies compared to commercial
high level matrices.

New Stationary Phases
New stationary phases are essential in
bioseparation sciences: classical phases
are already well developed and reach
their limits. The Bioseparation Engineering
Group is specialized on synthesis and
functionalization of magnetic particles
and conductive materials as well as their
process implementation. Making use of
magnetism or conductivity allows for an
additional degree of freedom for state-ofthe-art process development.

Wind energy technology
n The Wind Energy Institute (WEI) has defined four highly interconnected
thrust areas where it is concentrating its research activities: simulation,
testing, control and design. The institute works both on basic scientific
and application-oriented problems, often in close collaboration with
industry. Areas of specific expertise embrace all main relevant scientific
disciplines, including aerodynamics, structures, dynamics, materials,
controls and electrical aspects.

The institute staff has also a unique
experience in the development of scaled
wind turbine and wind farm models for
wind tunnel testing, which are among the
most sophisticated ever developed for
these applications.
In 2016 WEI will host the next edition of
Torque, the main scientific conference in
wind energy worldwide. We expect the
participation of over 300 researchers in
wind energy from all over the world, who
will be at TUM from Oct. 5 to Oct. 7 2016
to discuss the most recent advances in the
field of wind energy.
Scaled Wind Turbine and Wind Farm Testing

layer wind tunnel

tunnel simulation of a deep-water
floating cluster

WEI has developed a scaled experimental
facility for the simulation of wind turbines
and wind farms in a boundary layer wind
tunnel. This unique facility enables the
conduction of experiments in aeroservoelasticity, the study of wakes,
machine-to-machine interactions, and
wind farm control for power maximization
and load mitigation. The facility is highly
instrumented, allowing for the collection
of a wide range of high quality data, both
regarding the flow conditions and the
response of the machines. Such data can
be used for the verification of performance
of control strategies, as well as the
validation of computational tools. The
experimental setup is highly flexible, allowing for different machine configurations,
operational scenarios, and the testing of
different control algorithms used onboard
the individual wind turbines or the whole
wind farm.
Extremely interesting experiments have
been conducted in 2015, leading to the
first-ever experimental demonstration
of the effectiveness of wake-redirection
control in improving the power output
of a wind farm. Even more exciting new
experiments are planned for 2016.
A highlight of the year will be the wind
tunnel testing of a wind turbine cluster
made of 4 closely-spaced wind turbines
mounted on a floating platform, for deep
offshore installations. The tests will be used
to verify advanced control laws for the
operation of the floating cluster, including
extreme sea and wind conditions.

n Industrial project ‘Development and

funding)
Wind Sensing Technology
WEI develops technology for the use of
the wind turbines as wind sensors. By
the use of wind turbine response data,
as provided by sensors installed on the
blades or the nacelle, the technology
computes in real-time the wind conditions
at each machine, including wind speed,
wind direction, vertical and horizontal
shear, wake state (full, partial, no wake
interference) and turbulence intensity.
Such technology is capable of providing
detailed information on the wind conditions, in support of improved operation
of each machine or the whole wind farm
through smart control strategies. This may
lead to improved power output and power
quality, and to fatigue load mitigation. The
technology can also be used for very short
time assessment and forecasting of wind
conditions within a wind farm, with impact
on operation and control of the power
plant.
A highlight of the year was the first
experimental demonstration of the ‘wake
observer’, a novel software that can detect
the impingement of a wake on the rotor
of a wind turbine. In fact, when operating
within wind farms, wind turbines may
suffer severe losses due to interactions
with the wakes of neighboring machines.
The wake observer developed by WEI
researchers can be used for driving wake
redirection strategies, in turn increasing
power output and reducing loads.

Design of Wind Turbines
WEI works on the development of
automated multidisciplinary design
software tools, with the goal of enabling
the optimization of wind turbines, the
effective exploration of the design space,
the understanding of design trade-offs, as
well as the evaluation of the impact of new
technologies. Advancements in lightweight rotor design are being investigated
through improvements in the aerodynamics, in the structural design and the use
of smart sensing and control strategies.
By the combination of these technologies,
reduced ultimate and fatigue loads can
be achieved and exploited for decreasing
weight and improving performance,
thereby in turn reducing the cost of energy
from wind.
A highlight of the year has been the
release of a new version of the TUM wind
turbine design suite Cp-Max. The new
version of Cp-Max marries together for
the first time the preliminary and detailed
stages of the design of a wind turbine.
Using Cp-Max, engineers can more
rapidly and more automatically perform
the full design cycle of a new wind turbine,
gaining a better understanding of the
design space and of the tradeoffs implied
by different possible design choices.

Fundamental research on material behavior, processing technology
and simulation of high performance composite materials
n The focus of the Institute for Carbon Composites in 2014-15 was to
establish and strengthen its research program within the four research
groups. The main goal was to explore new ways and possibilities to
reduce the process cycle time and the raw material costs to be able to
implement high performance composite structures in high volume applications. Different process technologies using e.g. tailored textiles and
advanced matrix systems have been patented. New material models and
process simulation methods have been developed and these were implemented in conventional software tools to enable advanced composites
part and process design solutions.

Process Technology for Fibers and Textiles
The Process Technology for Fibers and
Textiles group focuses on improving
manufacturing technologies that arrange
the fibers in their desired orientation within
a composite component.
The group’s three research teams cover
the fields of braiding technology, automated fiber placement and tailored textiles.
With highly developed processing equipment, the fibers can be brought into shape
in an automated and reproducible way.
Fiber Placement Center
Many activities in 2015 focused on the
setting up of a new Fiber Placement Center
at the institute’s laboratory site on the
Ludwig Bölkow Campus in Taufkirchen.
Three different types of fiber placement
machines have been installed there to
form a unique machine park.
Machine Park
Besides a machine for the direct processing of fiber tapes with thermoplastic matrices, an additional machine for the use
of thermoset resin tapes has been set up.
This machine was moved from Garching
to Taufkirchen in summer. In the course
of this relocating process it was equipped
with an additional linear axis to increase
the production space. Both machines are
now capable of manufacturing composite
parts with a length of up to 5 m.
Furthermore, the Institute’s fiber patch
placement system will be relocated
to Taufkirchen as well. Thus, all these
different manufacturing processes can be
94
Newly set up automated fiber placement cell in
Taufkirchen
usefully combined e.g. to locally reinforce
big composite structures.
Collaborations
The full potential of the Fiber Placement
Center for the future development of
composite processing technologies
will leverage through direct interaction
with research and industry partners on
the campus. Especially promising are
collaborations with the institute’s spin-off
companies that are also located in Taufkirchen. These will greatly help to accelerate
transferring research results into industrial
applications

group addresses the robust and efficient
processing of matrix systems for the
production of continuous fiber reinforced
composite parts. On the one hand, the
basic understanding of matrix systems,
the characterization of impregnation
properties of the fiber material for optimized
processing, and process engineering are
central for the group. On the other hand,
associated issues such as tool technology,
surface sealing, and process integration
are key activities of the group.

with absorber materials is investigated to
reach more optimized conditions within
the production chain.
The LCC won the AVK innovation award in the
category ‘Research and Science’
The aim of the team is to expand the span
of applications of composites. One example
for this is the EU-funded project MATISSE
with the main partners Autoliv, Daimler,
Virtual Vehicle, TU Graz, Airborne and
TU Munich where a shape adaptive fiberreinforced crash structure was designed

braiding and automated fiber placement
as well as infiltration methods. Last year’s
activities focused on the characterization
of different materials. The goal of these
investigations is to determine material
properties and hence, simulation input.

draping and braiding processes were also

Compaction, Curing and
Consolidation Simulation
Research efforts in this team are dedicated to modeling of cure induced effects on
the final part’s properties and appearance
with a focus on compaction behavior and
porosity content, thermal management
and process induced deformations. In
2015, implementation and validation has
been concluded for modeling the thermal
management of large scale resin transfer
molded aerospace structures as well as
the consolidation of out-of-autoclave
prepregs. Magnitude and shape of global
deformation modes identified experimentally for a spar structure (featuring a
material with engineered vacuum channels
and manufactured with a caul) were
found to significantly differ from simulated
deformations, demanding more detailed
process modeling of complex structures.
To tackle this issue and gain further
insight in the importance of compaction
and resin flow related phenomena on the
part’s quality, future activities will focus
on transferring modeling capabilities from
lamina level to arbitrary three-dimensional
manufacturing setups.
Material Modeling and Structural
Analysis
The Material Modeling and Structural
Analysis research team focuses on the
structural analysis of fiber reinforced
plastics as well as mechanical and
bonded joints at different length scales.
One research focus is the prediction of the
constitutive behavior of textile-reinforced
composites using unit cells. A framework
is proposed predicting the non-linear
mechanical response of triaxial braided
composites using mesoscopic finite
element unit cells. In order to capture the
predominant failure modes observed in
braided composites, the model comprises
a physically based damage model inside
the yarns, plasticity in the resin pockets,
and delamination at the yarn-matrix
interfaces.
Another research area consists of the
non-linear behavior of angle-ply laminates.
A constitutive model for composite laminates is developed with the focus on the
distinction between inducing mechanisms.
It is shown, that the effect of fiber rotation
and damage is essential in consideration of
large deformations. To ensure the applicability to structural parts, the numerical
model is validated by a large number of
Roadmap and data flow for generating a realistic unit cell model for
braided composite materials

compression tests, fabricated of the same

Material Behavior and Testing

The Material Behavior and Testing group
focuses on the investigation of the material
response of fiber-reinforced polymer
matrix composites.
At the testing laboratories of the LCC a
broad spectrum of state-of-the-art test
methods and equipment is available,
covering thermo-analytical methods,
rheology and microscopy, experimental
methods to measure permeability and
drapability of UD and textile preforms, as
well as static and high strain rate mechanical testing.
An important focus of the group is on the
area of high strain rate testing, where split
Hopkinson bars for compression, tension
97
and torsional loading, installed in 2012
and 2013, are used to reach strain rates
of up to 1000 s-1.
In 2014 and 2015 various aerospace composite materials were investigated under
tension and compression loads at impact
rates of strain (bird strike scenario).
Recently the focus is on the development
and testing of high strength tension
specimens (e.g. UD glass-fiber composite
and fiber-metal laminates) as well as the
investigation of the fracture toughness
properties of composite materials.

Nonlinear Algebraic Multigrid for Multi-Physics Problems

Recent developments in the hardware
design of modern supercomputers allow
for fine-grained parallelism by accelerating
CPU-based computations with GPUs,
leading to a disruptive change in software
development. Besides a need for finegrained parallel storage management,
algorithmic questions and challenges
arise. To overcome some drawbacks of
classical Newton-Krylov solvers on these
new hardware platforms, we develop
a nonlinear algebraic multigrid solver
for coupled multi-physics problems. It
relies on an increased number of residual
evaluations, which show perfect parallel
scalability on these new machines.
In addition, all multi-physics coupling
terms are incorporated in the multigrid
coarsening procedure which leads to
improved performance especially in the
presence of strong interactions.
Image Registration and Inverse Analysis
Image registration plays a key role in a
broad variety of clinical and industrial
applications whenever information is
encoded by images. Especially in clinical
applications the acquisition of information
is highly based on imaging techniques,
such as computed tomography (CT),
magnetic resonance tomography (MRT)
or ultrasound. However, the bijective
characteristic of a transformation, i.e. the
unique and invertible mapping of material
particles, is not captured by the above
mentioned clinical imaging techniques.
Thus image registration for deformation
estimation constitutes an ill-posed inverse
problem which is in need of regularization
102
strategies. We focus on the application of
‘measurements’ from image registration
in material parameter estimation for finite
element models. Inverse analysis provides
a method to estimate material parameters
according to a given reference solution,
i.e. ‘measurements’. These measurements
can be obtained non-invasively, e.g. by
extracting deformation information from
medical images.
Numerical Prediction of Stent-Graft Deployment
in Abdominal Aortic Aneurysm
Endovascular aortic repair (EVAR) is a
widely used minimally invasive technology
to treat abdominal aortic aneurysm (AAA).
In this technology, a stent-graft (SG) is
inserted via the femoral arteries to exclude
the aneurysm sac from the main blood
flow. Consequently, a well positioned SG
within the AAA removes blood pressure
from the wall of the aneurysm sac and
AAA rupture is prevented. Most SGs
are composed of a wire mesh (stent)
consisting of nitinol which is sewed on a
polymeric fabric (graft). We aim at developing a predictive tool for the selection and
sizing process of SGs depending on the
patient-specific AAA geometry and hence
reduce the risk of potential
complications after EVAR (e.g.
endoleaks and SG migration). Such
a predictive, numerical tool based on
finite element analysis requires the combination of various complex simulation
components, such as contact mechanics
between AAA and SG, mechanobiology of
AAA, morphing strategies for the positioning of the SG and material modeling of
nitinol as shape memory alloy. Furthermore, meaningful long-term studies are
only possible if remodeling of the arterial
wall due to the additional interaction
between SG and AAA is considered.
Functional Modeling of the Heart and
an Extravascular Assist Device (VAD)
Due to decreasing number of transplantable hearts and deficiencies in current
heart assist device technologies, novel
concepts of extravascular heart assistance
are developed in close collaboration
between AdjuCor GmbH and MHPC.
The collaboration aims at minimizing vulnerable impact to the heart and optimizing
design and functionality of a novel device
by use of computational models.
Therefore, a strongly coupled 3D-0D
finite element model of the heart and the
vascular system is developed, which –
after calibration to patient-specific data
– is able to predict key features of cardiac
behavior in terms of physiologically
meaningful pressure-volume relations.
Furthermore, a realistic forward model of
the interplay between heart and device is
developed and integrated into an optimization algorithm, finding optimal device
operating conditions for ideal patientspecific treatment.
103
A Multiscale Model of Atherosclerosis
A multiscale and multidisciplinary
approach to the mechanobiology of
atherosclerosis is taken that is based on
computational techniques and experimental calibration and verification as well as
in- and ex-vivo molecular imaging. The
biological processes involved take place
at the (sub)cellular length scale and will
be assessed experimentally by histology
by our project partners from Klinikum
rechts der Isar. Based on the imaged
3D geometries, macroscopic computational fluid-solid interaction models with
transport, diffusion and interaction of
species and cells supply an understanding
of the local mechanical conditions which
can then be correlated to the biological
findings. A computational mesoscopic
biological model will be implemented
which will be coupled to the macroscopic
continuum representation of the region of
interest in a multiscale in time and space
framework. Imaging of several stenoses in
mice as well as carefully designed in vitro
experiments are applied to test the hypotheses of the model, calibrate its behavior
and evaluate its predictive capabilities.
Multi Objective/Field Optimization of
an Extravascular Assist Device (VAD)
Faster rescue chains and especially
improved clinical diagnostics and therapies have reduced the number of lethal
heart infarcts. More patients survive but
suffer from a resulting heart insufficiency.
At the same time, heart transplantations
are limited to the amount of donor organs,
which has been declining during the past
decade. A promising technology are
efficient cardiac assist devices. However,
the wide range of patient individual requirements makes it challenging to design an
appropriate device. Together with AdjuCor
GmbH, we develop a 0D model of the
driving unit of a novel VAD and couple it
to a 3D patient-specific heart model. This
allows us to iteratively optimize device
and implant in order to meet the individual
patient needs.

Quality control, non-destructive testing and structural health monitoring
n The focus of the Institute of Nondestructive Testing in the field of
mechanical engineering in 2014-15 was to establish NDT methods for the
inspection of fiber reinforced materials (CFRP and GFRP) together with
partners in the automotive and aeronautic industry.
Further research is conducted in the field
of wind energy: structural-health-monitoring of tower and basement and
non-destructive testing of rotor blades.
In civil engineering, the focus was on
inspection techniques for constructions

The leading edge cluster, MAI Carbon provides the unique opportunity to promote
non-destructive testing of fiber-reinforced
polymers on a large scale and to establish
them in an industrial environment. Within
the aerospace context, non-destructive
testing has already been used successfully for years. However, its usage on
fiber-reinforced polymers in automobile
manufacturing and engineering is still

in the early stages. At the same time,
requirements vary widely within the
industrial sectors and therefore require
new approaches to testing. Quantities,
which the aerospace industry produces
in a year, may be produced daily in
automobile manufacturing. The objective
of the MAI ZfP project is to investigate
which testing methods are applicable in
this context. For this, a round robin test is
conducted with several industrial partners.
Technical aspects as well as economic
factors influence the assessment. Results
of the round robin test will be presented at
the World Conference of Non-Destructive
Testing (WCNDT) in 2016 in Munich. The
overall goal is cost reduction in component production in order to increase the
competitiveness of German companies.
Numerous NDT techniques are applied
during the project including ultrasound in
reflection (phased-array), optical lock-in
thermography, modal analysis and local
acoustic resonance spectroscopy. The
project is funded by the Federal Ministry
of Education and Research (BMBF) and
the Bavarian Ministry of Economic Affairs
and Media, Energy and Technology.
Project: Concrete Pavement Scanner
Aging infrastructure is a major topic of
interest that also applies to road networks.
For targeted maintenance and repair
measures NDT tools to characterize the
current state of structural elements are
highly desirable. Concrete pavements
approaching the end of their service life
can suffer from damage not visible on the
surface but potentially affecting safety and
serviceability. Such damage includes horizontal cracks or delaminations within the
pavement structure due to heat induced
stress or detrimental chemical influences
for example. Although several non-destructive testing methods can be applied to
concrete pavements most of the conventional techniques like ultrasonics or ground
penetrating radar have drawbacks in
imaging the above mentioned defects. On
the other hand, testing methods based on
the propagation of elastic waves have high
sensitivity to flaws like delaminations and
have potential to be applied to concrete
pavements in an automated manner.
This project focuses on developing an
acoustic scanning method to image relevant damage inside concrete pavements.
3D sketch and implementation of an acoustic scanner prototype
The approach aims to develop a new
acquisition strategy for the so called
impact-echo method. Primary goals are
the development of sensing systems
based on microphone arrays specifically
tailored to the demands of concrete
pavement testing. Further, acquisition
strategies and hardware aspects for testing entire road sections will be examined.
The project is financed by the Federal
Highway Research Institute (BASt) under
the authority of the Federal Ministry of
Transport and Digital Infrastructure (BMVI).
Project: MISTRALWind
Within the next few years, many established wind turbines are going to reach the
end of their designed service life, which
is 20 years. Maintaining and operating
structural parts of wind turbines beyond
their nominal service-life makes sense
from an economical and technical point
of view. To reach this aim, a concept for
inspection and monitoring of structural
parts of wind turbines is developed in
cooperation with IABG, Siemens, Max
Bögl Wind AG as well as the Chair of
Structural Analysis and the Chair of Materials Science and Testing of the Technical
University of Munich. The workpackages
of the Institute of Non-destructive Testing
are focused on instrumented monitoring of
the tower and support structure of existing
and new onshore wind turbines. Furthermore non-destructive testing methods will
be identified which allow an assessment
of the actual state and by that enable an
extended service life.
With the aid of the acquired data, maintenance and servicing costs shall be
optimized. Beyond that evaluated data will
be employed as a basis for an extension
of the service life of wind turbines and for
the development of a control strategy that
considers the remaining service life. The
project is funded by the Federal Ministry
for Economic Affairs and Energy (BMWi).

in the seventh framework program. The
aim is the development of structures made
of self-healing concrete having an inherent
healing mechanism that becomes active
when a crack appears, thus rendering
manual crack repair completely obsolete.
In order to obtain such automatic crack
closure, HEALCON European project
partners are investigating the use of
PU-based polymer precursors, superabsorbent polymers and bacteria. The role of
the Institute of Non-destructive Testing is
the support of the design of such healing
agents as well as the development of testing methods as tools for the stakeholders
to prove the self-healing efficiency. Experimental results of small-scale tests confirm
the capability of selected NDT methods to
characterize material properties plus the
healing process and its efficiency.

Worker refueling a fuel cell-powered forklift at a
dispenser near the assembly line
Taking into account current economic,
ecological, social and technological
developments such as continuing volatility
of the markets, changing demography
and technological innovations, the focus
of the institute in 2015 was on designing adaptive/flexible, sustainable and
human-oriented/humane logistics systems
and technology. One highlight was the
testing of fuel cell-powered forklifts
and tugger trains in industrial practice.
That way, a reduction of global warming
potential could be achieved while the
trucks’ availability was increased at the
same time by the shorter time needed for
refueling. Thus, an economical application
of fuel cell-powered industrial trucks is
already achievable today with 2- or 3-shift
operation and where costs for labor and
area are high.
Innovative Conveyor Technology
High throughput, low energy consumption,
high flexibility and ergonomic design are
fundamental requirements for up-to-date
conveyor technology. Being part of a
multinational, interdisciplinary research
consortium, the Institute fml aimed to
develop a new wood chip feeding system
in the project ‘BioChipFeeding – Wood
chip feeding technology of the future
for small-scale biomass boilers’. This
technology provides a more efficient
combustion of the fuel in small- and
medium-scale heating plants. Therefore,
an automatically controlled gripper system
was equipped with various measurement
equipment, including a 3D camera system
and a moisture sensor. The system is
able to identify and reach for different
fuel qualities, depending on the operating
condition of the heating system. Blending
different wood chip qualities according
to a specifically developed algorithm
significantly reduced pollutant emission
and contributed to higher efficiency of the
overall heating plant.

Sustainable Logistics Systems
Sustainability is one of the biggest future
challenges forced by environmental,
economic and social developments; it is
ranked among the so-called megatrends.
This applies also to the field of logistics.
Above all in the stages of planning and
running a logistical system, aspects of
sustainability, i.e. the equipment’s energy
consumption, have to be considered.
For this reason we develop models for
predicting the energy consumption of
various means of conveyance. Furthermore upcoming concepts are evaluated
regarding their characteristics in terms of
sustainability. Beside the investigation of
fuel cell driven ground conveyors, the analysis of high bay warehouses built of wood
is another example. The research project
‘Wirtschaftliche und ökologische Potenziale von Hochregallagern aus Holz’ aims to
analyze the advantages and drawbacks of
high bay racking systems made of wood
in comparison to traditional constructions
made of steel. Therefore ecobalances and
life cycle costs are calculated to investigate the ecological sustainability and
cost effectiveness. Furthermore, new rack
structures are developed and optimized to

Planning and Control of Material Flow Systems
Material flow systems are more and more
complex due to the necessity of high
flexibility, fast modification and extension
of the systems according to changing
customer/user needs. In conventional
material flow systems, these modifications
may result in long periods of unproductive
reconstruction and reprogramming. The
main objective of the research project
IntegRoute is to avoid this by improving
the initial planning of in-plant milk-run
systems. To achieve this objective, an
approach for the integrated planning
of the technology, process and control
concept of milk-run systems is developed.
Furthermore, the approach will allow a
holistic assessment of planning alternatives concerning e.g. investments, operating cost, space requirements, ergonomics

and flexibility. Based on extensive process
analyses an MTM-based (methods time
measurement) model for calculating
the cycle time of milk-run systems was
developed. The model takes the interconnections between milk-run technology
and process workflow into account and
will be integrated in the holistic approach
for the initial planning of in-plant milk-run
systems.

Industry 4.0
The increasing demand for highly customizable products presents new challenges
to production and material handling
systems that have to deal with a larger
number of product variants. To respond
to the challenge of the constantly rising
complexity of today’s systems, the launch
of the Industry 4.0 aims at the deployment
of autonomous cyber physical systems
(CPS). These systems enable the efficient
management of complexity, while maintaining their flexibility and adaptability to
a fast changing production environment.
One research project, namely ‘ToolCloud
– Unternehmensübergreifendes Lebenszyklusmanagement für Werkzeuge in der
Cloud mittels eindeutiger Kennzeichnung
und Identifikation’ aims for the development of a cloud-based tool management
system for automated machine configuration and extensive tracking and tracing.
A data model as well as an IT-architecture
were designed therefore to enable automated communication and data collection
along the tool’s supply chain.

Humans in Logistics
Demographic changes and fluctuation
of employees lead to new challenges
in the design of logistics workplaces.
Workflows must be fail-proof, motivating
and efficient while at the same time
employees’ physical and mental stress
must be reduced. Research topics at the
Institute fml on the one hand focus on the
assessment of physical load at logistics
workplaces using different approaches,
and on their ergonomic design. In a
second line of research, namely in the joint
research project ‘GameLog – Gamification in der Intralogistik’ with the Chair of
Education and Educational Psychology
of the Ludwig-Maximilians University of
Munich, a totally new approach to foster
logistic staff’s motivation in logistics
workplaces is investigated: gamification.
Game elements and mechanics, e.g.
avatars, badges and high-score lists are
integrated into order-picking processes.
Laboratory studies show a significant
increase in employees’ motivation and
at the same time a reduction in picking
errors and picking time. In the next years,
this promising concept will also be tested
in industrial applications and possibly
integrated into commercial warehouse
management systems.

Crane Engineering and Design
of Load-supporting Structures
Research in the fields of crane engineering
and design of load-supporting structures
has a long tradition at the Institute fml.
One important topic of research is the
development of new calculation methods
for mobile cranes. These cranes are tall,
slender structures with acute-angled
suspensions. They show a strong nonlinear behavior near their load limits. In
industrial practice the analysis of these
cranes uses the quasi-static approach as
specified in EN 13001, EN 13000 and FEM
5.004 respectively. The investigation of
the cranes’ dynamic behavior by dynamic
finite element calculations partly showed
large deviations from the quasi-static
calculations according to the relevant
standards. The slewing process revealed
the biggest differences, followed by
hoisting and luffing.
In order to avoid time-consuming dynamic finite element calculations and to
overcome the lacks of the quasi-static
approach according to the standards,
efficient oscillation models are developed.
They enable the generation of quasi-static
loads, which represent the maximum
dynamic stresses with a very high
accuracy. Further research activities are
concerned with the integration of the

Experimental investigation and numerical simulation of flight propulsion systems and turbomachinery components
n Research activities of the Institute of Flight Propulsion in 2015 covered
topics in the fields of flight propulsion, gas turbines and thermal turbomachinery. Based on a long tradition the institute develops thermo-dynamic
engine models in order to investigate steady and unsteady gas turbine
engine and turbomachinery behavior.

The history of the Institute of Flight
Propulsion (LFA) reaches back until 1964,
when Prof. Münzberg was first appointed
to the head of the chair in downtown
Munich. Since its foundation the institute
has been dedicated to research and teaching in the field of jet propulsion and gas
turbines. The institute is an active member
of national research associations, participant in European research projects and
long-term partner of leading aero-engine
and component manufactures. One
highlight is the framework agreement
between the Institute of Flight Propulsion/
TUM, the Bavarian Government and GE
Global Research Europe. The cooperation
includes the development of the world’s
most advanced high speed research radial
and axial compressor laboratories focused
on developing tomorrow’s aircraft engines
and gas turbines. End of 2015 the first
test vehicle for the new axial compressor
testbed arrived at Garching and the commissioning of the entire rig already started.
Compressor Aerodynamics, Performance
and Operating Range Extension
The achievement of a high level of
efficiency in combination with the guarantee of aerodynamic stability is a main
objective in the design of highly loaded
compressors. Since the stability margin
drops critically with increasing stage
loading and transient operation, identifying
and understanding the mechanisms for
stall inception is the key to increase the
range of stable operation.
Unsteady flow simulations are applied to
investigate the phenomena inherent to the
development of aerodynamic instabilities.
For an investigated centrifugal compressor, the impact of newly designed and
circumferentially non-uniform inlet guide
vanes is studied. The simulation results
are validated against measurement data
currently acquired from the institute’s high
speed centrifugal compressor test rig.
Furthermore, casing treatments for multistage axial compressors are designed
numerically to passively extend the stable
operating range.
118
Tip blowing casing treatment applied to an axial
compressor including streamlines
The unsteady interaction between main
flow and the exiting and re-entering treatment flow is investigated using state of the
art phase lag simulations. Experimental
validation is performed in close cooperation with associated national research
institutes and industry partners.
Computational Aeroacoustics for Ducted
and Unducted Turbomachinery
Growing environmental awareness raises
demand for highly-efficient and low noise
emitting turbomachinery, guaranteeing
stable operation under a large range of
operating conditions. In order to improve
state-of-the-art turbomachinery, methods
for direct and hybrid sound prediction are
devolved and applied in combination with
high-fidelity computational fluid dynamics
analyses.
Based on time-resolved simulations of
the flow field, deterministic and nondeterministic sources for aerodynamically
generated sound can be identified to
deduce avenues for passively reducing
noise. The radiated sound field is then
determined by extrapolating the flow field
data into the acoustic farfield by means of
in-house acoustic solvers. Due to the high
computational effort involved in combined
aero and acoustic predictions, present
Methodology for hybrid acoustic
predictions relying on high fidelity
flow field simulations and in-house
sound extrapolation routines
research activities aim at developing low
order models for predicting sound from
propellers and open rotors. Consequently,
lower turn-around times for design
iterations can be achieved, thus offering
possibilities for automated aeroacoustic
optimizations and acoustic inverse design
of turbomachinery.
Supersonic Combustion Research
for Scramjet Applications
A scramjet (supersonic combustion
ramjet) is a future air breathing propulsion
concept for high speed vehicles traveling
faster than Mach 5. It is one of the most
promising propulsion concepts for future
space transportation systems and hypersonic flight vehicles.
Despite decades of research in this area,
scramjets still offer several unresolved
challenges. To achieve an air breathing
hypersonic flight one of the key technologies is supersonic combustion. At these
speeds, the residence time of air inside
the engine is of the order of milliseconds.
Therefore, mixing and reaction processes
in the combustor must be efficient and
very fast.
The internal flow of a scramjet combustor
is studied in a supersonic combustion test
bed at the Institute of Flight Propulsion.
Current research topics are related to
improving combustion stability, reducing
auto-ignition temperatures and increasing
combustor efficiency using catalytic
radical farming and the investigation of
the non-reacting and reacting internal flow
phenomena using optical measurement
techniques.

Compact Turboshaft Engine Quick-Start System
for Rotorcraft Applications
Turboshaft engine testbed
Current helicopters of the light and
medium class have two engines installed
due to safety reasons. However, this
installed power is rarely needed during a
flight mission and the engines are operating mainly in part load, leading to poor
specific fuel consumption. An operational
strategy during flight can be an intended
shutdown of one engine. The required
power is then covered by the remaining
engine which thus runs at higher loads at
enhanced specific fuel consumption.
Therewith, fuel can be saved, the mission
range can be enhanced and emissions
can be reduced. In case of a failure of the
remaining running engine, the shut-off
engine has to be quick-start capable due
to flight safety reasons. Quantification of
the fuel savings is a focal point of research
on intended single engine operation.
Since this engine usage strategy is limited
to certain areas of the helicopter flight
envelope, flight performance analysis
of the helicopter has to be performed in
advance. Then, realistic flight missions
are chosen for subsequent flight mission
simulation and evaluation regarding a
useful operational strategy. For realization
of engine quick-starts a new system was
developed and evaluated at the turboshaft
engine testbed. Its working principle
is based on air injection through Laval
nozzles inside the compressor section.
Therewith, a significant start-up time
reduction can be achieved. Since shop air
is actually used for the quick-start system,
an additional system is designed for independent air supply and for integration into
a helicopter airframe. For further investigation of the influence on the helicopter
drive powertrain, the testbed engine was
successfully coupled with the research
simulator of the Institute for Helicopter
Technology.
Structural Design and Optimization
of Aircraft Engine Components
Stress distribution in a generic
disk a) without and b) with heat
pipe

A higher turbine inlet temperature and the
reduction of component weight are key
parameters for a better overall efficiency
of future propulsion systems. This requires
new design concepts for turbine components. The new design should meet
or exceed the reliability requirements of
conventional designs. For their lifespan,
the dimensioning damage mechanisms of
turbine components are long-term creep
and thermo-mechanical fatigue. To meet
these requirements, two design concepts
are investigated. On the one hand,
additive manufacturing (AM) technologies
enable novel light weight structures. Using
the finite element method (FEM), a new
design method for additively manufactured turbine guide vanes with reduced
weight and unchanged functionality and
life span is investigated. On the other
hand, in order to cool and reduce the
maximum material temperature at the rim
of turbine disks, the use of high temperature heat pipes inserted into the disk
material is investigated.
Centrifugal Compressor Test Rig
Centrifugal compressor test rig
In the year 2010 a new high-speed radial
compressor test rig was commissioned in
cooperation with GE Global Research. The
latter meets the industrial standards for
design & testing and enables experimental
testing of different types of modern centrifugal compressors with drive power up to
800 kW and a maximum speed of 30,000
rpm. The test facility can be operated
either in open-loop or closed-loop configuration. The research activity focuses
on the optimization of centrifugal stage
components and their mutual interactions
in terms of efficiency and operation range.

Aerospace, the Chinese CSC and the
Brazilian CSF on environmentally benign
propellants for space-craft propulsion, the
group investigates within three individual
projects flashing of cryogenic fluids under
vacuum conditions, different propellant
injection concepts feasible for thrust
variation and in particular the concept of
resonance ignition where a gaseous sonic

Performance, efficiency and safety for rotorcraft
n The year 2015 brought a unique opportunity for the Institute of Helicopter Technology – five years after the institute’s foundation. The European
Rotorcraft Forum (ERF) is Europe’s largest scientific conference on all
aspects of rotorcraft research. Its location was planned for Germany this
year which gave us a chance to apply to host the 41st ERF at the Faculty
of Mechanical Engineering. Visitors and guests all confirmed their positive
feedback about the Forum, where 120 papers had been presented.
During Forum, the institute’s Research
Simulator ROSIE was frequently visited
by colleagues from other universities
(e.g. Maryland, GeorgiaTech, Cranfield)
or experts from operations and industry.
Finally, it was also a dry-run for the next
event: the 2017 conference of the German
Aerospace Society (DGLR) with around
1000 participants!
A major event marked the beginning of
2015 when the Federal Ministry of Economy (BMWi) published the preliminary
votes for the latest LuFo-Call (National
Aviation Research Program). Although
LuFo is mainly devoted to aviation industry, the Institute for Helicopter Technology
(HT) was successful in three projects.
With our partners at TU Chemnitz and
Hochschule Hannover, we will investigate
the use of structural parts manufactured
from renewable raw materials. Concrete
applications will be designed together with
a manufacturer of ultra-light helicopters.
The second project will focus on the sizing
and design of helicopter drive systems,
where substantial variations of the rotor

Co-axial helicopter (edm-aerotec) for LuFo project
CuRoT
rpm shall be enabled by new gearbox technologies. The Partner for this project will be
TU Vienna where modelling and testing of
such gearbox designs are foreseen.
Finally, HT will have a unique chance to
perform measurements of a counterrotating (i.a.w. co-axial) main rotor of an
ultra-light aircraft which was developed
and manufactured by edm-aerotec, a
medium-size company in Thuringen. The
German Aerospace Center (DLR) will be a
key partner for all aerodynamic measurements. In two of these projects, work has
begun already by mid 2015.
Real-Time Downwash Modeling of Helicopter Rotors
Real-time simulation (snap shot from video) for a
tiltrotor close to ground.
One of the helicopter’s major drawbacks
lies in its principle of (vertical) flight: its
downwash from the rotor disk allows the
helicopter to hover – but it generates high
wind speeds which can produce clouds of
sand, dust (brownout) or snow (whiteout).
These clouds are a major hazard for
operations close to the ground or in the
vicinity of obstacles as we know from a
series of severe accidents. One way to
limit the risk associated with brownout
or whiteout is an optimal training in flight
simulators. However, there is no adequate
modelling available to represent the clouds
as induced by the downwash. This was
127
motivation enough to start research on
real-time capabilities of simulation models.
A first dissertation is about to be finalized
this year and first results were presented
at the Forum of the American Helicopter
Society and at the European Rotorcraft
Forum. The next milestone will be a
cooperation with the American Office of
Naval Research where ship landings will
be in the primary focus.
Rotorcraft Drones for Extreme Altitudes
Rotor blade for the AREA drone
manufactured at TUM
Together with the DLR Institute of
Robotics in Oberpfaffenhofen, HT is working on an extreme helicopter application:
A drone (AREA) with a maximum weight of
25 kg shall be enabled to fly to an altitude
of 9000m – autonomously!
Besides the requirement to control the
aircraft under severe gusts and crosswinds, the required power is a major
challenge. A relatively large rotor radius
has been selected therefore – leading to
an unusual structural requirement for the
blades. The sizing and design of the blade
was part of a Master thesis which received
the MT Aerospace Innovation Award
during the German Aerospace Congress
(DLRK) in Rostock.
This work is supported by a Munich
Aerospace Scholarship and performed in
Garching and Oberpfaffenhofen.
Pilot Assistance for Degraded Visual Environment
Pilot’s view during flight into
degraded visibility; combined
natural outside view and display
symbology (center image)
Despite today’s achievements in active
and passive safety measures, helicopter
flight still requires research efforts e.g.
for flight in degraded visual environments
(DVE).
To overcome the challenge of extending
the flight envelope to such degraded
visual conditions, current research focuses
on head-mounted displays with 3D- conformal (scene-linked) visual cues for pilot
assistance.
‘Pilot-in-the-loop’ simulations are required
to increase the maturity of this techno-
128
logy. New approaches and concepts of
displaying 3D-conformal information are
developed to reduce visual clutter and to
enable spatial situation awareness. Thus,
landing zone symbols together with terrain
and obstacle information can be displayed
for collision avoidance.
During 2015, the symbology was
developed far enough so that the next
step – the system evaluation – could be
envisaged. Symbology assessment in
helicopter cockpits requires skilled pilots
to be interviewed after they have ‘flown’
a new cockpit design. The key question
behind: Does additional symbology
increase the pilot workload or does it help
reduce the risk of pilot mistakes? Or – in
a nutshell – is there a net benefit of such
additional pilot aids?
After a long preparation, the simulator is
finally ready for these evaluations. They
began in mid 2015 and will take till the
beginning of 2016.

During the last years we have acquired all
the experience which is needed along the
whole process of making control ideas
fly. This includes modeling and system
identification, controller design and
implementation in real aircraft.
Our research areas are presented in
the following sections. The research
infrastructure includes several flight
simulators, test rigs, and manned and
unmanned aircraft. We have established
important partnerships and synergies
with top research institutions and leading
industrial players in the field of aerospace.
Our ultimate goal is the development and
the application of innovative approaches
tailored to real world applications and
products, as well as to the demanding
challenges of tomorrow.
Flight Guidance and Flight Control
Research airplane Diamond DA-42
130
Modern flight guidance and control
systems need to fulfill the growing
requirements for safety, performance and
autonomy in order to comply with customers’ needs. To this end, novel methods
and concepts are being developed at TUM
FSD for manned as well as for unmanned
aerial vehicles. The practical relevance of
the results for the specific applications is
guaranteed through continuous evaluation
of the research during flight tests.
Notable achievements 2014-2015
include the development and testing of
an integrated auto-flight control system
incorporating waypoint based trajectory
flight, autopilot functionalities and direct
law fly-by-wire algorithms. Aircraft-inthe-loop simulations using the actual
institute’s DA-42 aircraft and a real-time
simulation setup have been conducted
to verify the developed algorithms and
prepare upcoming flight tests. Novel
adaptive control algorithms that enable
controlled flight along highly agile and
nonlinear trajectories and in the presence
of actuator faults have been developed
and successfully flight-tested on multirotor
systems.
The flight control and flight guidance
group has successfully completed several
research projects and has acquired new
collaborations with the industry. Project
results and ongoing research have been
presented at PARIS AIR SHOW 2015,
AIRTEC 2014 and 2015, ILA 2014 and
various scientific conferences.

Unmanned hexarotor system
Modeling, Simulation, Parameter Estimation
and Flight Safety
The research group Modeling, Simulation,
Parameters Estimation and Flight Safety
focuses on the modeling of flight vehicle
systems on the one hand and predictive
analysis tools on the other hand. The
parameter estimation approach is based
on measured input and output data of the
real system. Flight vehicle system identification focuses on the aircraft dynamics
and on modeling the forces and moments
acting on it. The result is a validated
model with known uncertainty bounds
that is reliable in a known region of the
flight envelope. System identification
techniques allow comparison and combination of dynamic models from very
different sources, e.g. from flight test data,
wind tunnel tests or computational fluid
dynamics, leading to very accurate results.
The system identification group focuses
on unmanned aerial systems and general
aviation aircraft. In doing so, the group is
contributing to many projects. This includes the modeling of fixed wing aircraft,
helicopter and multicopter systems. The
identified models were used, for example,
as the basis for the model-based design
of flight control systems and as flight
dynamics model in high fidelity flight
simulators.
The flight safety part focuses on the
quantification of incident probabilities for
a given airline based on information about
the flight operation. Predictive analysis,
which is conducted at our institute, refers
to making a quantitative statement about
a future state or condition based
on previous experience or knowledge. It
focuses on quantifying the probabilities of
serious incidents for an individual airline,
which are extremely small, yet not equal to
zero. Predictive analysis will be an integral
part of the box of tools that will keep the
skies of tomorrow safe!

Trajectory Optimization
FALCON.m, FSD optimal control
in MATLAB
In the Trajectory Optimization Research
Group at FSD, optimal control methods
for aerospace applications are researched
and developed. These methods are
tailored to specific applications, mainly
from the field of aerospace. One part of
the process is the modeling of specific
cost functions representing the key
performance indicators that are relevant
for industry.
Among these are the calculation of fuel
consumption, flight times as well as the
modeling of noise and its perception
by the inhabitants around an airport.
Additionally, multiple aircraft optimization problems have become a focus of
the research group. In these problems,
several aircraft have to fly through a
shared airspace sector minimizing the
environmental impacts while always
maintaining all safety boundaries. Of
course, in all applications the compliance
with aircraft-related envelope constraints
as well as regulatory constraints has to be
ensured.
The results achieved in the research
projects have been used to create
scientific publications and were additionally condensed into a software tool,
called FALCON.m. This tool is planned to
be released in early 2016 to the general
public and will enable the solution of
132
optimal control problems in different fields
of engineering and sciences all around the
world.
Finally, a project has been conducted in
close cooperation with the flight control
research group of the institute and Prof.
Ben-Asher from Technion – Israel Institute
of Technology (Haifa, Israel). Within this
project, optimal control methods have
been used to perform a flight control law
clearance. This way, it can be proven that
the flight control system is able to maintain the aircraft within a secure envelope in
any considered flight condition.
Additional research topics were the
solution of optimal control problems including discrete controls. Furthermore, the
combination of classical optimal control
methods with alternative approaches was
investigated. In a DFG project started in
2015 the robust solution of aircraft trajectory optimization problems is researched.

Avionics and Safety Critical Systems
Traditionally, the research at FSD was
focused on functions and algorithms. With
the new focus on prototyping application
systems with small and medium enterprises
as main partners for UAS/RPAS and general
aviation aircraft, implementation aspects
have gained high importance. With the cost,
weight, volume and other constraints of the
markets addressed and the limited personal
and financial resources of typical SMEs,
a transfer of solutions, processes, components and tools from large and military
aviation would lead to a gigantic failure.
Based on the specific requirements of the
market considered and utilizing disruptive
technologies and innovations from nonaerospace domains, tailored processes,
tools and solutions are required. Research
focuses are model-based design of functional algorithms for guidance, navigation
and control applications, model-based safety
assessment as well as the development
of avionics system architectures and the
contributing components (flight control
computers, data concentrator units, electromechanical actuators, navigation systems
and power system components). The work
is accomplished in close collaboration with
highly innovative SMEs, manufacturers of
RPAS and general aviation aircraft as well
as tool vendors.
The FSD has gained novel capabilities in
failure simulation with minimal additional
modeling effort, reducing the workload for
safety assessment and system integration.
Projects
n Development of certifiable flight control
system architectures for RPAS up to
150kg MTOW (ZIM)
n Development of internally redundant
electro-mechanical actuators with
backup flight control capabilities (ZIM)

n Assisted model validation against
safety requirements using failure

Sensors, Navigation and Data Fusion
Navigation systems and sensors provide
essential information on aircraft state
required for flight control and guidance,
such as position and angular rate. Consequently, the performance of flight control
greatly depends on navigation accuracy.
In addition, safe and successful mission
accomplishment requires high availability
and robustness of navigation with respect
to faults or disturbances.
From the combination of various satellite
navigation, to the development of fault-tolerant ADAHRS algorithms, the Navigation
Research Group at FSD the development
and studies application of innovative
methods in the field of navigation. In
2015, the navigation group established an
Inertial Sensor Test facility that will boost
research in the field of inertial sensor
calibration and error estimation.

Applied aircraft design for civil aviation and unmanned aerial systems
n System integration and validation for unmanned aerial systems have
been in the research focus of the Institute of Aircraft Design in 2015.
Based on the design capabilities and previously realized demonstrators,
UAS key system components have been implemented and tested under
real conditions. As part of those activities a new test lab for complete UAS
propulsion systems has been built up, in order to test electrical propulsion systems up to small jet engines featuring active thrust vectoring
capabilities.
Univ.-Prof. Dr.-Ing.
Mirko Hornung
For the design and operational assessment of commercial aircraft the capabil
ities in the operational assessment have
been enhanced with respect to noise
and emission assessment as well as
quantifying the capacity impact on airport
operations. The optimization of reduced
noise configurations has been enabled
through an innovative noise assessment
procedure developed for small aircraft.

Noise Evaluation
Multi-engine UAV for
noise measurements
For inflight noise assessments and model
validation the institute operates highly
precise noise measuring equipment.
Through the integration of test results in
a tool-based noise modeling algorithm
directional noise models of aircraft
configurations may be derived very
efficiently. These models may enable
Noise abatement procedures
136
noise-restricted aircraft operations as well
as the derivation of reduced-noise aircraft
configurations.
As annoyance due to aircraft noise is
becoming a major issue at a growing
number of airports around the world, the
pressure to reduce the noise impact in the
vicinity of airports increases. Following
this need, one focus of the Institute of
Aircraft Design is the comparison of noise
abatement procedures and the evaluation
of their application for specific airports.
In this, apart from noise reduction at the
source, a variety of operational, economic
and restrictive instruments exists enabling a relief of residents in the vicinity of
airports.
UAS Aircraft Design
The integration of simulation-based design
methods for unmanned air systems (UAS)
or remotely piloted air systems (RPAS)
enables a more consistent design process
for such air vehicles. Connecting the
operational or mission environment with
sensorics and/or communication systems
as well as other payload systems allows
an early integration and assessment of
novel air vehicle architectures.
The visualization tool enables representation of a high number of information, such
as: aircraft configuration, its performance
and position, commanded and real flight
paths, communication capabilities, sensor
range and field of view, interaction of the
system elements with each other and the
environment.
The numerical simulation is based on a
mission management system, flight control system, as well as the information from
the mission payload and is represented in
MATLAB Simulink. The relevant input data
are connected with the institute’s ADEBO
and ADDAM tools. The visualization is
based on the OpenSceneGraph toolkit.
These two parts are connected via a user
datagram protocol, which is also used for
the feedback information to the design
process.
The goal of the software is to enable a
mission scenario building, to evaluate
sensor and mission performance, taking
into account all components of a UAS and
their interaction with the environment.
Utilizing the enhanced integrated design
environment ADEBO (Aircraft Design Box)
the foundation for more efficient aircraft
conceptual designs for unmanned as well
as manned aircraft have been laid.
UAS design: mission simulation
tool
UAS System Testing and Demonstration
Propulsion systems and their integration
in unmanned aircraft are key enablers for
novel systems. TUM LLS with the support
of the Federal Ministry of Economic
Affairs of the Free State of Bavaria has
set up a unique UAV propulsion test
facility enabling the integrated testing of
electric propulsion systems up to small jet
engines. Providing the unique features of
the test lab, also thrust vectoring devices
may be tested.
The test lab has been first utilized for the
analysis and optimization of the SAGITTA
propulsion system. Featuring highly
complex intake and nozzle technologies a
thorough test campaign has been conducted to further enhance the propulsion
system’s performance.

Novel Flight Control Devices
Illustration of Coandă flap concept
The Institute of Aircraft Design has achieved
major progress in the development of
a tool for a functional driven design of
advanced flight control systems. Here,
advanced flight control systems (AFCS)
consist of multifunctional, highlyintegrated control surfaces, including new
technologies, configurations and innovative flight control system architectures.
To design efficient flight controls systems
with highly integrated flight control surfaces, the flight control system architecture – regarding power systems, actuators
and flight control computers, among
others – plays a special role and has to be
considered too. Therefore, a tool for the
pre-design of flight control system architectures for a given flight control system
configuration is developed, considering
the main functional, safety and certification aspects.
Finally it can be stated, that this functional-driven, highly-integrated approach
enables new design spaces for flight

In parallel, novel technologies for flight
control devices on modern agile UAVs
or even new concepts of aircraft configurations are under investigation. In the
field of active flow control a separation/
circulation control concept is assessed
for highly dynamic flight control purposes.
Since the early 1970s this ‘Coandă flap’
concept has been successfully tested
under laboratory conditions and it was
implemented on a few general aviation
test carriers and unmanned prototypes.
For the investigation of the application
potential on modern (unmanned) largescale aircraft a novel numerical toolset
has been developed, combining simplified 2d CFD-models with extrapolation
techniques for finite low aspect ratio
wings. Overall system performance is
assessed by including all relevant system
interfaces and dependencies in a 6-DOF
flight dynamic simulation implemented in
MATLAB/Simulink combining all submodels
for performance analysis. Trim calculations
and dynamic simulations gave evidence
for the feasibility in terms of sufficient
effectiveness of the studied Coandă flap
system for the given low aspect ratio flying
wing configuration.

n In 2015 the focus of research
at the Institute of Plant and
Process Technology was the
energy efficient design of chemical
production processes as well as
innovative design methods for
process equipment. After commissioning the 1.2 m diameter packed
bed test column in 2014 the
gas capacity of the column was
successfully increased in 2015.
Extensive experimental measurement campaigns were successfully
conducted and valuable data for
validating numerical models for the
maldistribution behavior of packed
columns could be achieved.
The new high pressure phase equilibrium
test rig was operated in 2015 over the
whole year to determine the important
influence of water on the solubility of
technical solvents such as methanol and
glycol ethers. Reliable analytical and
synthetic measurement techniques were
applied such that gaps in the literature of
technically important solubility data could
be closed.
Packed column test rig (1.2 m diameter)
Process Design
The limited availability of fossil resources
is leading to an increased demand for
energy efficient processes. For this task
optimization is a key discipline that aids
engineers with designing new processes
New hybrid approach for process optimization
142
or revamping existing plants. Process
simulations are usually performed with
commercial programs, which allow fast
and reliable simulation setups but have
limited capabilities for optimization. An
innovative option would be to use the
benefits of both methods; a flexible and
customizable optimization platform that
is combined with process simulators for
an efficient problem setup. To achieve
this a hybrid approach is chosen.
MATLAB is used for optimization since a
variety of local and global optimization
routines are available directly or as third
party library. As an example, the hybrid
approach is used to obtain an optimal
synthesis gas production for methanol
synthesis with respect to operating
expenses. The increased number of
objective function calls due to gradient
approximation leads to a high calculation time when compared e.g. to an
algebraic modeling approach. However,
for engineers far less time is required for
problem setup and initialization. Therefore, the strategy shows the potential
to substantially decrease the actual
man-hours for process design.

Condensation on a low-finned tube
Equipment design is of increasing importance for enhancement of the energy
efficiency of processes. Heat exchangers
are the most employed apparatus in the
chemical industry. Innovative design can
increase transfer rates and thus enable a
better heat integration in processes which
leads to a reduction of CO2 exhaust.
Therefore, the utilization of low finned
tubes for condensation of mixtures of
hydrocarbons was investigated. Besides
an extensive experimental measurement
campaign, condensation on the tubes was
also studied with CFD simulations.
Together with partners from industry, a
model for dimensioning mass transfer
columns, based on CAD data of packing
elements, is developed and tested at
the institute. In addition to tests with the
column with 1.2 m diameter at the institute,
experiments were also carried out with a
column with 2.0 m diameter at an industrial
partner’s facility.

Modeling and Thermodynamic Property Data
Electro mobility becomes more and more
important in the future. Therefore, fuel
cells in cars come into focus of research.
A new test stand for measurements of
permeabilities through polymer membranes was assembled at the Institute of
Plant and Process Technology in close
cooperation with an industrial car manufacturer to investigate humidification of air
supply for fuel cells. In 2015 a wide range
of membrane materials from different
suppliers were tested and evaluated such
that the most promising candidates for the
Membrane permeability test rig

technical application could be identified.
Based on quantum chemical simulations
and statistical thermodynamics predictive
computation of thermodynamic and thermophysical property data was performed
with the method COSMO-RS for various
substances and mixtures at the Institute of
Plant and Process Technology. A powerful
computer infrastructure provides the
required computational resources.
In 2013 the high pressure phase equilibria
test stand was successfully commissioned
at the Institute of Plant and Process
Technology. As a first example the system
methanol-CO2 was experimentally investigated in 2014 and data which is consistent with literature could be obtained and
was published in 2015. Reliable analytical
and synthetic measurement techniques
were applied such that gaps in the literature of technically important solubility data
could be closed.

Predictive computational modeling
n The focus of the Continuum Mechanics Group in 2015 was the
development of novel models, methodologies and computational tools for
quantifying uncertainties and their effect in the simulation of engineering
and physics systems. Our work has been directed towards three fronts:
a) the calibration and validation of computational models using experimental
data, b) uncertainty propagation in multiscale systems, c) Design/control/
optimization of complex systems under uncertainty.

A highlight was the organization of the
international Symposium on ‘Big Data and
Predictive Computational Modeling’ that
took place in TUM-IAS during May 18-21
2015. The symposium was sponsored by
the European Office of U.S. Aerospace
Research & Development (EOARD), the
TUM-IAS and the Department of Mechanical Engineering. It included plenary and
keynote talks from pre-eminent scientists
in applied mathematics, computational
physics/chemistry, computer science and
engineering.
The event received considerable interest
from various communities and an article
on it appeared in Volume 48, Number 6
of SIAM news. Videos and slides from the
symposium can be found at: http://www.

Excerpt from SIAM news article
(Volume 48, Number 6) on ‘Big
Data and Predictive Computational Modeling’
Nonlinear Inverse Problems with Applications
in Medical Diagnostics
This project is concerned with the numerical solution of model-based, Bayesian
inverse problems. We are particularly
interested in cases where the cost of each
likelihood evaluation (forward-model call)
is expensive and the number of unknown
(latent) variables is high. This is the setting
of many problems in computational physics where forward models with nonlinear
PDEs are used and the parameters to
be calibrated involve spatio-temporarily
varying coefficients, which upon discretization, give rise to a high-dimensional
vector of unknowns.
Our motivating application is biomechanics where several studies have
shown that the identification of material
parameters from deformation data can
lead to earlier and more accurate diag146
nosis of various pathologies. This project
develops Bayesian computational tools
that can lead not only to point-estimates
of the material properties, but also to a
rigorous quantification of the confidence
in those estimates. A significant role in this
effort is played by novel dimensionality
reduction techniques which can identify a
sparse set of features. One consequence
of the ill-posedness of inverse problems
is multi-modality i.e. the possibility of
multiple, distinct solutions that fit the data
comparably well. We developed adaptive
strategies that are capable of accurately
capturing the presence of multiple modes.
Coarse-Graining in Equilibrium Statistical Mechanics
Identification of material parameters using nonlinear, incompressible elasticity models.
(a) Ground truth (reference)
Coarse-grained (CG) models provide a
computationally efficient means to study
large numbers of atoms over extended
spatio-temporal scales. Existing strategies
rely on mapping degrees of freedom from
micro- to macro-scale, whereas properties
are commonly determined as certain
point-estimates in the macro-scale.
Various methodologies that have been
proposed do not account for the information loss which unavoidably takes place
during coarse-graining. The joint project
‘Predictive Materials Modeling’ with Hans
Fischer Senior Fellow Prof. N. Zabaras
(Director of Warwick Centre for Predictive
Modeling, University of Warwick) addresses the formulation and development of
(a) Coarse-graining of water molecules
(b) Multimodal posterior mean. Points on the boundary
have non-zero probability of belonging to healthy
tissue (blue) or tumor (red)
an enhanced, predictive multiscale framework. Our reformulation of coarse-graining
follows a data-driven, Bayesian paradigm
based on generative probabilistic models.
It builds upon: a) a coarse macroscopic
description, and b) a probabilistic lifting
operator, reconstructing micro configurations from coarse states. This affords a
more flexible definition of CG variables,
the rigorous quantification of uncertainties
associated with using limited training
data and various degrees of information
loss. Furthermore, it is capable of identifying sparse representations for the CG
potential which reveal qualitative, physical
features of the CG model.

Reduced-order Modeling for Uncertainty Quantification
(a) True (reference) solution
manifold in three-dimensional
phase space.
(b) Mixture of local, reduced-basis identified from data.
Each color corresponds to a different reduced-basis
set associated with a particular subdomain of the input
space.
Reduced-basis construction for
Kraichnan-Orszag nonlinear ODE
with parameters/inputs being the
initial conditions and time.
As the physical problems become more
complex and the mathematical models
more involved, current computational
methods prove increasingly inefficient,
especially in tasks requiring numerous
solutions as in uncertainty quantification.
In the latter case, the difficulty is further
amplified by the large number of input
parameters (random variables). This
project employing advanced, statistical
learning tools in order to develop probabilistic reduced-basis models. These consist
of mixtures of reduced-bases which can
be used to project the governing equations in order to obtain descriptions of
significantly lower dimension. The tools
developed can learn reduced-bases sets
from a limited number of full-scale runs
and can simultaneously partition the input
and output space so that different response
regimes can be computed as well as the
most important/sensitive inputs can be
identified.
Design in the Presence of Uncertainty
Topology optimization problem.
Deterministic (left) vs. Stochastic
(right) solutions. The stochastic

148
(a) Deterministic solution
(b) Stochastic solution (mean)
This project is concerned with a lesserstudied problem in the context of
model-based, uncertainty quantification
(UQ), that of optimization/design/control
under uncertainty. The solution of such
problems is hindered not only by the
usual difficulties encountered in UQ tasks
(e.g. the high computational cost of each
forward simulation, the large number of
random variables) but also by the need
to solve a nonlinear optimization problem involving large numbers of design
variables and potentially constraints. We
propose a framework that is suitable for
a class of such problems and is based
on the idea of recasting them as probabilistic inference tasks. To that end, we
developed a variational Bayesian (VB)
formulation and an iterative VB expectation maximization scheme that is capable
of identifying a local maximum as well as
a low-dimensional set of directions in the
design space, along which, the objective
exhibits the largest sensitivity. In cases
considered the cost of the computations
in terms of calls to the forward model was
of the order of 100 or less. The accuracy
of the approximations provided was
assessed by information-theoretic metrics.

One of this year’s highlights was the
publication of a review in Trends in Microbiology, which describes mathematical
models that are able to reproduce diauxic
growth behavior in bacterial systems.
This behavior is a hallmark of bacterial
regulation and was first discovered by the
Nobel laureate J. Monod. These models
can be classified according to a number of
criteria as regulation dependent, resource
dependent, dynamic, or static.
Fundamentals for Experimental Analysis and
Mathematical Modeling of Cellular Networks
Regulation of transcriptional and biochemical processes in a bacterial cell
is essential for surviving in changing
environmental conditions and understanding of the events taking place is pivotal
for using bacteria in industrially interesting
applications. Research of the systems

or the ComRS two component system in
Streptococcus mutans. The experimental
information derived either in the group’s
own laboratory or by collaboration
partners gives rise to mathematic models
that contribute to a better understanding
of cellular processes.
Another research focus lies on the
establishment of a co-culture between
a photosynthetically active organism
extruding sugar molecules together with
heterotrophic organisms capable of producing industrially interesting compounds.
To this end a photobioreactor is employed
which allows cultivation and collection of a
vast amount of data used to describe the
population-based variations in the overall
process.

Metabolic Engineering of Halophiles:
Towards Halomonas elongata as Industrial Producer
The project focuses on ectoine production
by the halophilic bacterium Halomonas
elongata. The reasons for that choice are
not only the interest of ectoine as a novel
product for medicine and cosmetics but
also the potential of H. elongata for further
biotechnological applications. Ectoine
is a highly soluble organic molecule that
belongs to the group of compatible
solutes and is found as an osmotic agent
in a wide range of cell types and has also
been shown to stabilize and protect macromolecules in adverse conditions. The current applications of ectoine cover a wide
range of different fields like biomedicine,
cosmetics, support roles in analytic and
industrial processes and bioremediation.

Biomechanics Group
Mechanics and permeability of biological (hybrid-)materials
n The mission of the biomechanics group is to:
1.discover new, to date unknown material properties of biopolymer
materials;
2.identify the microscopic principles that govern those material
properties (mechanics, permeability);
3.apply those principles to synthetic polymers to create biomimetic
materials for biomedical applications.
The studied biomaterials range from
very soft gels such as vitreous humor
and mucus to stiff tissues such as
cartilage. Accordingly, a broad variety of
characterization methods is used in the
Biomechanics Group. Biomedical questions addressed include tattoo removal,
prevention of microbial infection and
reduction of wear in osteoarthritis.
In our highly interdisciplinary projects, we
work together with chemists, pharmacists,
physicists and medical researchers to
generate, characterize and optimize existing and novel biopolymer-based materials
and to test their applicability for biomedical
or industrial purposes. Highlights in the
year 2015 were the development of a
molecular repair mechanism for damaged
mucins (the main components of e.g. saliva
and tears) and the successful transfer of
microbial mucus penetration strategies into
an artificial microswimmer system.

the wound gel we are engineering needs

properties. We also embed nanoparticles
for a controlled and prolonged release
of drugs that benefit the wound healing
process. In the long run, we aim at replac

emphasis on electric mobility. Vehicles are not only considered as a whole
but components are also optimized, infrastructure is examined and users
are supported by driver assistance systems.

Participants of the conference WKM symposium
This cooperation is not only strengthened
in projects but also in various events. For
this reason, the so called ‘Forschungsfahrt’ was offered in March 2015, giving
industry professionals in-depth insights
into the main focuses of research at the
institute. In addition, the institute organizes both the annual Conference on Future
Automotive Technology, with a focus
on e-mobility, and the driver assistance
conference, which takes place every
two years in cooperation with TÜV SÜD.
Furthermore the travelling conference
WKM Symposium was held at the institute
in July 2015 addressing PhD students
both at university and in industry.
Vehicle Components
Vehicle test with the QuadRad
156
The research group of vehicle components
is concerned with all kinds of vehicles.
The requirements and target groups have
a wide range. While the institute particularly focuses on the comfort of the driver
in the field of trucks, safety plays a major
role in small and lightweight vehicles.
The department also operates in the field
of micro vehicles. A special vehicle for
individual transport was developed in
2015:
The so-called ‘QuadRad’ is a type of
bicycle with four wheels and electric
pedal assistance. The vehicle concept
is designed especially for commercial
applications. Research in the field of
courier services have shown, that the use
of electric cargo bikes is more economical
compared to cars and bikes. By using
a pedelec engine the annual mileage of
bicycles can be increased by a factor of
1.8. Thereby the higher vehicle costs can
be compensated effortlessly. With the
same mileage, an electric cargo bike is
more profitable than a car. Compared to a
conventional bicycle or a cargo tricycle the
QuadRad offers a large transport capacity,
with a significantly higher driving comfort
and simultaneously increased safety.

E-mobility and Infrastructure
Live simulation of an electric vehicle using the smartphone app developed by the institute
The main problems of electric cars
today are the short range and the lack of
infrastructure for fast charging. Furthermore high battery costs lead to expensive
buying costs and make electric vehicles
less attractive compared to internal combustion engine cars. For these reasons the
institute focuses not only on components
of electric vehicles but also on fleet tests
with electric vehicles in order to analyse
the behaviour of different user groups.
Thereby the use of all means of transport
is included in the research activities and
therefore the whole mobility behaviour can
be recorded. The aim of these studies is
to discover the requirements on electric
vehicles for different target groups and
places as well as the requirements on the
necessary infrastructure.
Within the project VEM the mobility behavior of taxis and commercial vehicles
have been tracked with the help of smartphones. Based on a detailed mobility
analysis, the potential for an upcoming
electrification for various use-cases is
assessed. This includes a simulation of
both different electric vehicle concepts
and the needed charging infrastructure.
The proposed simulation model allows to
compare various scenarios in a short time,
with relatively little effort. This way the
optimal charging infrastructure configuration and the ideal battery size is specified.
All results are orientated to actual needs
that arise within different fields of application.

Driving and Driver
Driver information and the driving task
itself is crucial with regards to safety. The
research in this area focuses on accident
prevention and avoidance, and integral
vehicle safety. Among other things, a
dynamic driving simulator is used in
order to carry out driving tests in a virtual
environment. Due to this simulation
environment the experiments are free from
external interference and can therefore be
reproduced exactly. In addition, the simulator enables a harmless representation
of critical traffic situations and extreme
driving manoeuvres. Thus, new systems
can be tested in realistic scenarios in
a very early, prototypical stage of the
development.
Actual driver assistance systems are
mainly used on highways. They are highly
accepted by the drivers and mostly seen
as useful. Special challenges concerning
technical systems, coordination and
acceptance by the drivers are met in
urban traffic scenarios. As driving in an
urban scenario is nearly unpredictable,
and therefore not useful for explorative
studies, we integrated more simulators
(truck and car) in a network. Scenarios
were developed and tested without any
risk for others. Interactions of the urban

Most projects are situated in the field
of innovation & creativity. Together with
industrial partners, the institute works on
topics like user experience, bio-mimetics
and open innovation (represented in three
projects).
The institute has a long tradition in the
field of systems engineering and engineering design processes: In this field, the
institute works on four projects within the
Collaborative Research Centre SFB 768
and on several projects in collaboration
with large companies as well as small and
medium enterprises (SMEs).
Knowledge and approaches from systems
engineering are also transferred to the
research field of knowledge management.
Facing the challenge of the huge amount
of employees carrying knowledge for
fulfilling tasks, the structural complexity
approach helps handling these domains
and deriving measures.
Finally, projects on the topic of cost
management deal with the challenge of
early determination, but least causing of
costs.
Innovation & Creativity
environment. Research helps to develop
sustainable product architectures, find
new ideas using methodologies of the
Open Innovation toolbox and implements
new organizational models following the
principles of Open Organization.
Column model of opening strategies
162
The current research activities of the
Institute of Product Development in the
field of innovation and creativity aim at
the integration of relevant knowledge from
various disciplines of product development. The institute mainly refines design
methodologies and adapts processes in
companies.
An essential component of research
are applications within an industrial

The Institute of Product Development
has a long tradition in integrated product
development. In recent years, research
activities of systems engineering were
performed to react on the increasing interdisciplinarity of product development and
to benefit from synergies. Research focus
of the department is the development of
product architectures as an important
link between requirements analysis
and design of individual components.
Methodologically seen, the institute mainly
works based on the approach of structural
complexity management.
A major result in this field is the developed
guideline for a market-oriented top-down
modularization tailored to machine and
plant engineering.
Projects
n DFG SFB project A10 – Analyzing the
dynamics of cyclic interactions in PSS
n Industry project – Development of a
market-driven system and product
strategy for brake control systems

modularization
n DFG SFB project T1 – Methodology
for creating cycle-robust module and
platform strategie
n KME project – A2TEMP
n Industry project – Implementation of a
modularization strategy
Development process of
mechatronic products
Engineering Design Processes
Research activities on engineering design
processes focus on the development
of efficient procedures for the design of
complex technical products and product service systems (PSS). The most
important premise when analyzing and
improving processes is the company- and
situation-specific support of developers.
In particular, the underlying product
structure, the organizational conditions
and the dynamics of internal and external
factors for a targeted design process are
taken into account.
Projects
n DFG SFB project A2 – Modeling and
evaluating development relationships
across disciplines
n DFG SFB project B1 – Cycle-oriented
planning and coordination of development processes
n DFG SFB project C2 – Lifecycle-driven

Knowledge Transfer & Management
right employees. Due to the increasing
flow of information and growing amount
of unstructured data, this often is an
unmanageable challenge. The institute
faces this challenge with approaches from
system engineering.
Knowledge flows in product
development and application
In addition to knowledge transfer between employees and the maintenance
of knowledge portfolios, the research
focus in this field is making existing
knowledge of proven solutions available.
A key factor for successful product
development is providing the information
on best practices within the company and
across companies at the right time to the
Projects
n BFS project FORPRO2 – Methodological toolkit for systematic evaluation
of design solutions
n BFS project FORPRO2 – Processoriented requirements in simulation
management
n KME project – Systematic development
of a company’s knowledge
n BMBF project – ConImit: Protection
against product piracy
n DFG project – Knowledge development
Cost Management
In the area of cost management, the early
phases of the product life cycle, the cost
responsibility of designers and the necessary cooperation between various internal
departments and external corporate
points are emphasized. Designers and
engineers are supported by the research
activities of the department for product
development in various areas. Thus,
methods and tools are designed to enable
cost estimates during early phases of
product development and to make them
thorough and reliable.

Model-based analysis and design allow for the successful control of complex dynamical systems
n The institute is focused on both, the development of methods and their
application. In order to allow for an efficient control of technical processes,
new techniques are devised in nonlinear control, energy-based modeling
and design, model order reduction, as well as adaptive and predictive
control. Moreover, a Collaborative Research Centre puts a spotlight on the
modeling and analysis of nontechnical systems. From an application perspective, highly challenging problems include the treatment of vibrations
in automobiles, the robust control of multicopters, the control of unstable
robots, and the feedback control of industrial processes.
Active and Semi-Active Suspension Control
developments of our research include
the development of a nonlinear feedback
control in combination with nonlinear state
observation techniques. Thereby, different
design objectives can transparently be
achieved, while design restrictions like
state and input constraints can be taken
into account.
The so-called hybrid suspension system,
developed at our institute, is depicted in
the figure; it includes a low-bandwidth
actuator F(t) and a high bandwidth
variable damper dc(t), together with a
sophisticated control system.

Model Order Reduction
When a load F(t) moves along an
elastic structure, a time-varying
high-order model results, which
requires reduction before further
use in analysis and controller
design.
The modeling of dynamic systems
frequently leads to large sets of differential
equations. The goal of model order reduction is to find a much smaller (reduced)
model that preserves the most important
properties of the original model. Recent
research in our group deals with reducing
parameter-dependent systems, timevarying systems and systems of differential algebraic equations. The resulting new
methods guarantee high approximation
accuracy, while being numerically efficient
and preserving important system properties like stability or passivity.

Model Predictive Control for Highly Dynamic Systems
Quadrotor – the designated
controller test platform
Within the last decades, immense growth
of the available computational power has
enabled the embedded implementation of
optimization-based control approaches
for systems with fast dynamics. The
main strength of the model predictive
control (MPC) paradigm is the possibility
to systematically consider constraints
on the input and state variables. Still,
the real-world application of nonlinear
MPC remains challenging, as non-convex
optimization problems have to be solved
online with sufficient accuracy in order to
obtain desirable closed-loop dynamics.
Currently, a novel control concept for
multirotor systems using adaptive and
predictive components is developed in
collaboration with the Institute of Flight
System Dynamics.
Modeling and Control of Distributed Parameter Systems
Partial differential equations can be
used to characterize systems whose
parameters depend not only on time
but on a spatial variable as well. Such
systems include all kinds of transport
and diffusion phenomena as they arise
for example in the movement of beams
or in air flowing through a tube. Firstly,
research is dedicated to a new approach

an undamped wave equation

for the identification of parameters in
linear partial differential equations. Based
on the thereupon parameterized model,
secondly, model-based control techniques
are applied to achieve a desired dynamic
behavior of the distributed parameter
system. Currently, research interests are
focused on a pneumatic line with nonlinear friction.
Energy Based Modeling and Control
One focus of research is the design and
application of energy-based control
approaches to mechatronic systems.
Two examples are velocity- and position-
control of the mini wheeled inverted
pendulum (see section Takagi-Sugeno
Systems) and the design of observer-based
controllers for linear port-Hamiltonian
systems using a dual approach. Another
main topic is the modeling and control of

systems governed by partial differential
equations. A current DFG project deals
with the control design based on spatial
discretizations that preserve structural
properties in terms of energy and conserved quantities. A modular flexible robot
is currently under construction as a lab
demonstrator for the developed methods.
Our scientific exchange with IIT-Bombay,
India (DAAD) continues while EU Marie
Skłodowska-Curie Actions help to extend
our network to France.
Takagi-Sugeno Models and Controller Design
Most robotic systems exhibit unneglectable nonlinearities in their system
dynamics, which are to be considered in
the design process of the controller. One
approach is to use interpolated linear
models, so-called Takagi-Sugeno models,
to represent the dynamics of nonlinear
systems and to use these models for
analysis and control design.
Within the collaborative research centre
‘Zyklenmanagement von Innovationsprozessen’ of the German Research
Council (DFG), the modeling and analysis
of non-technical dynamical systems is
investigated by the use of Takagi-Sugeno
models.

n The focus of the Institute of Micro Technology and Medical Device
Technology is to accelerate the process of developing ideas into products. In research and science, the time required for implementation is
a significant factor for success. Therefore, rapid prototyping and rapid
manufacturing technologies are part of our main research interest. We
are systematically developing and analyzing new rapid technologies, as
well as applying them in the areas of precision engineering, micro technology and medical device technology. We are systematically validating
our research devices to achieve reliable scientific results. In the area
of medical technology, we develop according to ISO 13485, certify our
devices according to MDD/FDA and perform clinical studies according to
ISO 14155.
This year a new clinical prototype was
developed in cooperation with our long
term partner inomed Medizintechnik
GmbH. During the ZIM project Intraoperative Tremor Assessment, funded by the
Federal Ministry for Economic Affairs and
Energy (BMWi). A sensor module was
developed that can assist the neurologist
assessing the Parkinson symptoms during
the implantation of deep brain stimulation
electrodes. The sensor communicates with
the inomed Neuro-Monitoring System and
provides essential information, where to
implant the electrode and hence possibly
improve the operation outcome. The Prototype was developed regarding the medical
device directive. Its clinical evaluation with
our clinical partners at the Klinikum Groß-
hadern is ongoing. The system is planned
to be included in inomed’s product-portfolio at the end of 2016.
Task-Oriented, Computational Kinematic Design
Kinematic synthesis of a compact,
origami-inspired spatial car door
guidance linkage, which eases

parking spots (MiMed)
174
The initial and fundamental idea of
mechanism and machine theory consist
in designing mechanical devices with
task-specific mobility and dimensions and
represents also one of the basic design
methodologies behind mechanical and
robotic motion systems developed at the
institute. Latest examples of such systems
include novel laparoscopic or endoscopic
medical devices, assistive transfer devices
for elderly people up to specifically
moveable car doors. These all rely on
mechanical linkages, which are known to
form an essential functional basis defining
the motion properties of detailed machine
designs. In this context, the major goal of
the kinematic design group is to provide
computer-aided analysis and synthesis
methods that allow for the design and
prototyping of novel task-specific motion
systems. Due to a task-specific number
of degrees-of-freedom such systems
may provide robust and energy-efficient
solutions in a variety of different technical
applications. Recent research results of
the group include the development of
new computational analysis and synthesis methods for a novel compact class
of origami-inspired spatially movable
linkages as well as a novel CAD-integrated
kinematic design tool addressing virtual
A spherical two-degree-offreedom linkage for the spatial
orientation of endoscopes and a
corresponding workspace analysis

prototyping of motion systems. Another
highlight this year was the 11th German
Conference on Linkages and Transmission Systems (11. Getriebekolloquium),
organized by the Institute.
Open Dynamic Real-time Interconnection
of Medical Devices
The rapid progress in the digitalization
of devices and systems in the operating
room and clinic allows for thoroughly
novel methods in diagnostics, planning,
therapy, post-operative care and clinical
documentation. During an intervention,
devices and systems aggregate digital
data that could be used for various
purposes – say, intraoperatively to support
the surgeon or postoperatively for subsidiary documentation of the intervention.
However, the interfaces providing this
data are not yet standardized and hence
cannot be used for automatic processing
by other devices.
The networks and navigation group at the
MiMed has a leading role in the German
flagship project ‘OR.Net‘. The goal of this
project is the establishment of a communication standard for devices and IT
in the operating room and clinic. With its
in-depth experience in the field of real time
communication and development of real
time capable devices, MiMed supports
the project in the elaboration of viable
solutions for (closed loop) control of time
critical devices such as drills, coagulators,
shavers, ultrasonic knives etc. The newest
results are continuously transferred to
MiMed’s lectures. MiMed’s knowledge
in the field of regulatory affairs is equally
important, as existing strategies and
regulations in the field of medical devices
must be modified to allow for certification
of open, dynamically changing interconnections.
During the course of the last year, the
networks and navigation group has
elaborated technologies to exchange real
time critical data of medical devices over
an open and standardized communication
infrastructure. To this end, the group has
developed several modules allowing the
connection of existing devices to the real
time communication network. To prove the
benefit of data presented in a standardized fashion, the group has developed a
module that interconnects two distinct
navigation cameras and merges their
data to enlarge the visual range of the

image data that stem from various image
sources. A test platform, specifically
designed for the project, is capable of
measuring delay and jitter of transferred
data to ensure real time capability of all
network participants.
To address regulatory affairs issues and
risk management, the group works on two
additional projects: one is a library
that generates digital models of the
interconnected device architecture based
on formal descriptions of the standalone
devices. The other is the design and
implementation of a database system for
the consistent documentation of medical
devices – a system that was honored with
the best paper award on an international
conference of experts.

Technology for an Aging Society –
Custom Structures for Wearable Aids
Nursing often requires high physical
effort of care-givers. Patient transfers,
in particular, increase their risk for
musculoskeletal disorders. One of our
goals is to improve this situation through
wearable aids that enhance strength and
assist during intense labor. Therefore,
we evaluate cutting-edge technologies
such as passive strength enhancing
textiles, e.g. Japanese Smart Suits, at
a cooperating nursing home in order to
extract promising principles. Additionally,
we collaborate with specialists in orthoses
and prostheses in order to acquire the
necessary skills to create custom-crafted
structures that fit the human body. Combining these approaches we deduce new
fields that go beyond the state of the art.
In particular, we focus on techniques that
produce physically optimized wearable
structures automatically based on their
biomechanical parameters, for example
the automated layout of cutting patterns.

Rigid custom structure made by handcraft methods
(MiMed)
These automated techniques are expected to benefit orthopedic technologies
directly as well as improve the physical
human-machine interface of wearable
robots. These individualized wearable
aids will assist during patient transfers
and thereby improve the situation of both
care-givers and elderly people.
Automated Design Concepts for 3D-Printing
One common task in engineering and
other technical disciplines is the reali
zation of ideas as functional prototypes.
Since the 1980’s 3D-printing technologies
are used for the production of single
parts for prototypes. If standard machine
elements or complex and personalized
structures should be 3D-printed, the
most time-consuming and therefore
expensive part is the design process. In
order to speed up the design process
one research area of our lab focuses
on design automation. The idea is to
implement design algorithms for standard
machine elements such as springs,
gearwheels, shafts or clips that can
automatically adjust the parameters
based on desired mechanical properties,
the available 3D-printing technology and
the chosen material. Besides the mechanical durability of designed parts we
also predict their producibility based on
tolerances and limitations of 3D-printing
technology, such as layer height, laser
focus diameter, minimal wall thickness
or minimal gap width. One of last year’s
milestones was the publication of a first
usable library with basic design algorithms implemented in MATLAB. Ongoing
projects focus on design algorithms
for the automated individualization of
surgical tools and manipulators or the
automated design of gear drives.

Nuclear engineering and nuclear safety
n The focus of the Institute of Nuclear Engineering in 2015 followed
the research lines started and developed in 2014. Our activity has been
dedicated to the development of multi-physics nuclear safety methodologies based on coupled code systems; simulation of the behavior of
plant components; experimental two-phase flow thermal-hydraulics; the
development of uncertainty methodologies in multi-physics and medical
applications, the simulation of nuclear fuel behavior; the development of
advanced molten salt reactor concepts, and the development of a methodology for local stability analysis of nuclear reactors.

Nuclear Reactor Safety Analysis of
Current and Future Reactor Designs
The research in nuclear safety carried out
at the Institute focuses on the development and applications of methodologies
to support the safe operation of nuclear
reactors. The methodologies are based on
a multi-physics approach which combines
computer codes capable of detailed
simulation of different important physical
processes that determine the behavior
of nuclear systems. Computational fluid
dynamics (CFD) codes such as ANSYSCFX and OpenFOAM are coupled in real
time with a detailed neutronic description
of the core behavior provided by state-ofthe-art, multi-dimensional, time-dependent neutronic programs such as PARCS.
The detailed local description obtained of
the thermal-hydraulics and neutron flux
distribution can be used for full system
simulation analysis with codes such as
TRACE and ATHLET.
Multi-physics, statistically-based uncertainty and sensitivity methodology applied to experimental assessment
of coupled codes (G. Clotaire PhD Work)
180
In 2015, this research line has been
carried out through projects which focus
on the development of uncertainty and
sensitivity methodologies for multi-physics
applications to the assessment of computer codes in the context of liquid metal fast
reactors; the development of an advanced
model for turbine modeling based on
parameter estimation techniques and
online sensitivities; the completion of
PhD theses on the simulation of condensation induced water hammers and on
the development of a new approach to
the identification of unstable behavior in
BWRs at the fuel assembly level.

Experimental Two-Phase Flow Thermal-hydraulics
Experimental facility for research on condensation in
suppression pools (by Dr. S. Al Issa)
The Institute has built in the past four years
an experimental laboratory for two-phase
thermal-hydraulic research. A trend for
increasing detail in the predictions of
thermal-hydraulic coolant and moderator
behavior in nuclear safety research is
widespread in the world, and CFD codes
fundamental tools in this respect. But their
performance in nuclear safety applications
for current and future reactor designs
needs to be thoroughly assessed before
their predictions can be accepted by the
nuclear regulatory authorities. The facility at
the Institute deals with two very important
two phase flow phenomena, such as
counter current flow limitations (COLLIDER)
and steam condensation (SCUBA). Both
facilities can be flexibly reconfigured and,
in the course of a PhD work finished in
2015, have been equipped with advance
measurement optically-based techniques
for the characterization of two-phase
interfacial phenomena. Additionally in 2015
a new facility has been built to study the
condensation phenomena in suppression
pools in collaboration with the Polytechnic
University of Madrid.

Development and Design Optimization
of the Dual Fluid Reactor (GFR) Concept
The Dual Fluid Reactor (DFR) is a new
concept of nuclear systems based on the
Molten Salt Reactor (MSR) design; one of
the Generation IV reactor types currently
under development. It has been conceived
by the Institute of Solid Matter Physics (IFK)
in Berlin and has the innovative feature of
using a second molten metal as coolant.
This configuration possesses many advantages with respect to the MSR and to other
current and advanced reactor concepts,
which have the potential to make the DFR
a competitive reality in the future. Its ability
to destroy the long-lived minor-actinides in
burnt fuel and its extremely efficient use of
nuclear fuel resources are two fundamental
characteristics for its attractiveness.
Scheme for the thermal-hydraulic and neutronic
simulation coupled multi-physics simulation of molten
salt reactor concepts (Xun He PhD Work)
181
The Institute has been involved in this
design for three years, in collaboration with
the IFK, and has performed development
and analysis work in the context of two PhD
projects that are part of the multi-physics
line of research described above, but
applied to advanced reactor concepts. Two
coupled computer analysis systems based
on the codes ATHLET, TRACE-PARCS and
SERPENT (Monte Carlo transport code)
have been developed which are capable
of detailed design optimization and safety
analyses of neutronic and thermal-hydrau-
lic aspects of the DFR and of any fluid
core-based nuclear system.
Projects
n Development of a coupled neutronic
and thermal-hydraulic model for the
Dual Fluid Reactor Concept (molten
salt coolant, E.On Kernkraft)
n Development of a full system thermalhydraulic and neutronic model for
molten core based reactors (E.On

Fuel Behavior Analysis
Fuel assembly bowing caused by
mechanical loads in the core of a
PWR. (A. Wanninger PhD Work)
182
Fuel behavior analysis is a very important
part of nuclear safety research, because
the neutronic, thermal and mechanical
performance of nuclear fuel decisively
influences the safe and economical operation of nuclear reactors. The research
activities have continued on the modeling
of fuel and in the validation of computer
codes that simulate its behavior under a
wide range of operating and off-operating
conditions.
Thus, a project has focused on the investigation of the long-term creep deformation of PWR (pressurized water reactor)
fuel assemblies (FA), commonly known
as FA bow, by using the finite element
method. The research on new fuel types
has developed a new version of the fuel
performance code TRANSURANUS, in
collaboration with the Institute for Trans
uranic Elements (ITU) in Karlsruhe, for
thorium-based fuels ((Th,Pu)O2 and
(Th,U)O2) including the complex phenomenon of fission gas release. Collaboration of the Institute with the CEA and
E.On has produced two completed PhDs
on LOCA behavior of highly-burn-up fuel,
coupling of TRANSURANUS with the
neutronics code DYN3D and the on-going
PhD work in the behavior of new fuel
materials in LWRs.

Experimental and computational acoustics – vibroacoustic optimization – uncertainty quantification
of vibroacoustic systems – structure-fluid interaction – material data identification
n The institute has been created out of an existing group of scientists
that moved to the TUM in July 2015. The focus of this professorship will
be to set up a research group dealing with all kinds of problems in vibro
acoustics and adjacent areas.
The Institute for Vibroacoustics of Vehicles
and Machines was founded on 1 July
2015 with the appointment of Prof. Steffen
Marburg to fill the Gerhard Zeidler endowed chair at the Faculty of Mechanical
Engineering of the Technische Universität
München. Previously Prof. Marburg was
Professor for Engineering Dynamics at the
Universität der Bundeswehr in Neubiberg
and he moved together with his complete
group of seven scientists to Garching.
Professor Marburg is part of a national
and international network in both academia and industry. Recent collaborations
have taken place with the University of
New South Wales in Sydney and Can-
berra, the Indian Institute of Technology in
Delhi, the Technical University of Chemnitz, the universities of A Coruña, Naples,
Concepcion and Vienna as well as with
local and international industrial partners
from the automotive industry, software
developers and other industrial branches.
Prof. Marburg is an active member of
the German Acoustical Society (DEGA)
and one of the chairs of the Technical
Committee on Computational Acoustics
of the European Acoustics Association.
Furthermore, he is Associate Editor of
three international journals: Acta Acustica
united with Acustica, Journal of Computational Acoustics and Acoustics Australia.

Scientific Interests
with colleagues in mathematics, electrical
and civil engineering, medicine, biology
and music.
HVAC vibration test in anechoic chamber
The topics of research at the Institute
of Vibroacoustics of Vehicles and Ma
chines encompass many applications of
acoustics and vibrations. Carrying on from
previous activities, the research will be
quite interdisciplinary including joint work
Scientific interests require a strong basis
of experimental and computational
abilities. For this, it is planned to purchase
good basic experimental equipment and,
in the medium term, an acoustic laboratory including an anechoic chamber and a
reverberation room, both connected by a
window test rig. Research in computational acoustics will continue developments
in the context of finite and boundary
element methods as well as development
and application of simulation models
using commercial software such as Ansys,
Abaqus and Comsol. In addition to these
activities, the group is well-known and
well-experienced in the field of structural
acoustic optimization. It has been shown
that numerical optimization can easily
achieve much better engineering designs
than manual engineering work.
In recent years, the group has been known
as one of the very few groups worldwide
Institute of Vibroacoustics of Vehicles and Machines 185
to identify parameter uncertainties on an
experimental basis. This technique is quite
useful in characterizing and investigating
lightweight materials in the context
of non-destructive testing for quality
management and damage identification.
Moreover, the group is experienced in the
identification of the material properties of
anisotropic elastic lightweight materials
on behalf of vibroacoustic experiments.
Often, these experiments are much better
suited for determination of elastic material
parameters than any other method.
Simulation model of metal forming
tool
The techniques mentioned above can
be applied to very different technical
problems. Vehicles and vehicle parts are
obvious applications. However, in recent
years, these vibroacoustic methods have
been applied to various different domestic
appliances, used for quality management
of tool blanks and fruits, simulation of
musical instruments and development of

A number of other research projects and
topics have been dealt with in recent
years. These include non-linear vibration
phenomena such as self-sustained vibrations of hand-held electric tools, i.e. mode
locking of a rotor, and stick-slip vibrations
of a brake system. Another, quite different
application is the dynamic behavior of a
metal forming tool which will be continued
in the direction of fatigue prediction. The
group is also active in the field of aeroand hydroacoustics and the problem of
sound propagation in moving media.

Properties and optimisation of materials facing high temperature plasmas
n The focus of the Plasma Material Interaction Group in 2015 was to
finalise the quality assessment of the actively cooled high heat flux components of the new stellarator Wendelstein 7-X, to study the morphology
and composition of dust particles in various fusion devices as well as the
production and testing of novel materials for plasma facing components.

Actively cooled plasma facing component during high heat flux test at neutral beam facility GLADIS (Photo: IPP)
A highlight was the successful completion of the quality assessment of the
actively cooled high heat flux components for Wendelstein 7-X, which is the
world’s largest stellarator built by the
Max-Planck-Institute for Plasma Physics
(IPP) in Greifswald, Germany. From 2005
to 2010 a total of 60 prototypes for the
actively cooled components were tested.
In this period of time a production technology fulfilling the requirements of long
pulse operation was developed in cooperation with Plansee SE. The prototypes
of the pre-series have confirmed the
robustness of the finally selected design
and technology. Prototypes specified
for long pulse operation at 10 MW/m²
were successfully loaded at 30 MW/m²
in the high heat flux test facility GLADIS
operated by the PMI group.
Owing to its two ion sources of 1 MW
power each, its 8 m³ vacuum chamber
and powerful water cooling, GLADIS
offers the possibility to investigate small
scale as well as full scale objects loaded
with extremely high heat fluxes. From
2011 to early 2015, 86 of the 970 delivered components were evaluated. For this
purpose all CFC (carbon fibre composite)
tiles were loaded with 100 cycles of 10
seconds duration at 10 MW/m² (see figure).
The surface temperature increase of the
CFC tiles during the cycling caused by the
thermo-mechanical load was evaluated
statistically. It was possible to show that
the probability of an undetected defective
CFC tile is negligibly low.
Besides withstanding severe thermal and
mechanical loads the armour materials
of plasma facing components must be
erosion resistant and the retention of
hydrogen isotopes must be low. In order
to understand and to test material properties, a variety of preparation methods
are used, as well as a comprehensive set
of techniques for physical, chemical and
mechanical characterisation is available
within the PMI group.

Investigations on Composition and Morphology
of Dust from Fusion Devices
Various erosion processes in fusion
devices can lead to the production of
dust. Accidental air or steam ingress in
future power plants could cause significant production of explosive hydrogen on
the reactive surfaces of the dust particles.
Furthermore, dust could negatively impact
operation when entering the confined
plasma. For both issues, its occurrence,
morphology and composition is important
in order to facilitate safety considerations
and to provide input for model calculations.
Whereas in devices with graphite based
plasma facing components the large
erosion through plasma particles leads to
thick deposited hydrocarbon layers which
eventually flake off, arcs and excessive
power loads can create droplets in
devices equipped with metals as plasma
facing material (PFM).
In order to investigate and document
the influence of the PFM, dust particles
were collected in the three fusion devices
ASDEX Upgrade (AUG, Germany), DIII-D
(USA) and LHD (Japan) [M. Balden et al.,
15. Conf. on Plasma Facing Materials and
Components, Aix en Provence 2015]. The
three devices involved utilise PFMs ranging from pure carbon (DIII-D), over carbon
and steel (LHD) to full tungsten (AUG).
For gathering and analysing the dust, the
strategy developed over the last years
at AUG was applied using Si collectors
mounted for one experimental campaign
inside the device at various locations.
The dust was analysed automatically by a
scanning electron microscope equipped
with energy dispersive X-ray spectroscopy
(EDX). For all collectors at least ~5000
dust particles were analysed, providing
robust statistics. More than 90% of
190
Electron microscopic images (left: surface, right:
cross section, produced by focused ion beam) of dust
particles extracted from the fusion device ASDEX
Upgrade
all particles from DIII-D collectors are
composed of C (with contributions of O,
B, and N), while in LHD this fraction is
below 50% with about 20% of all particles
containing more than 5 at% metal (Fe).
For the AUG collectors, the fraction of
tungsten containing particles is in the
range between 50% and 80%. Spherical
particles, which are significantly present in
AUG and indicate molten metal or strong
plasma contact (see figure), are almost
missing on the DIII-D collectors and are
sparsely present on the LHD collectors.
The particle size distribution, which could
be described for different classes of dusts
from AUG by a log-normal distribution, is
different for the dust originating from LHD
and DIII-D. Specifically, in the fully graphite covered device DIII-D the frequency
of very small and large dust particles is
larger compared to that in AUG and the
total amount is also larger by 1-2 orders
of magnitude hinting again at the different
production processes.
Mechanical Properties of
Tungsten-fibre-reinforced Tungsten
Crosssection of Wf/W composite
after a Charpy impact test: The
tungsten fibres show ductile
deformation and pull-out leading
to increased toughness of the
composite
Its combination of unique properties
makes tungsten a promising candidate
for plasma-facing components in a future
fusion power plant. However, its inherent
brittleness and corresponding lack of
damage tolerance considerably limit its
use.
A possible solution/improvement is to
incorporate fibres in the material producing a kind of toughness, viz. increased
resistance to failure. The embedded fibres
can bridge or deflect cracks, or plastically
deform.
During the past years W samples reinforced with coated long W fibres (Wf/W)
from drawn tungsten wires could be
produced on a laboratory scale (60 x 60 x
3 mm³, 2000 fibres). Charpy impact tests
on the ‘as produced’ samples (conducted
at Institute of Materials Science and
Mechanics of Materials, TUM) showed
increased fracture energy mainly due to
the ductile deformation of the tungsten
fibres (see figure). Three-point bending
tests with ‘as produced’ samples showed
stable crack propagation and rising
load-bearing capability still after crack
initiation. Interface debonding and crack
bridging could be directly observed. Even
after reaching the maximum strength no
catastrophic failure appeared, but only
a reduction of load, revealing the ideal
composite behavior.
In the view of fusion application this
ductility in the fibres might get lost due
to accidental thermal overload and the
embrittlement through neutron irradiation.
In such a fully embrittled case (reached by
heating the sample at 2000K for 30min)
still crack bridging by the fibres and a
rising load-bearing capacity was observed,
albeit only up to lower maximum load.
These experimental observations prove
that the toughening in Wf/W is still effective
after embrittlement. The results illustrate
that the use of Wf/W could broaden the
operation temperature window of tungsten
components significantly and mitigate
problems of deep cracking occurring
typically in cyclic high heat flux loading.

State-Space-Models for Combustion
Dynamics and Acoustics
Long-term efforts to develop state-space
formulations for generation, transmission
and scattering of sound in ducted configurations made very significant progress in
2015. A unified framework for integration
of a wide range of models in the in-house
acoustic toolbox taX was developed.
Generation, propagation and dissipation
of sound in combustion chambers,
ventilation ducts or exhaust systems may
now be modelled in a flexible and very
efficient manner. Powerful tools are now
available for the analysis of thermo- or
aero-acoustic instabilities.
State-space models also played a crucial
role in the development of robust, flexible time-domain impedance boundary
conditions for numerical simulation of
compressible flows. The new boundary
Phase portrait of velocity during
period-2 oscillation of unstable
premix flame with compressible
(blue) and incompressible (red)
flow model (from Jaensch et al,
2015)
conditions made possible for the first
time the investigation of nonlinear dynamics and bifurcation studies of unstable
premixed flames with CFD.

Identification of Noise and Uncertainty
Significant progress was achieved in the
concurrent identification of noise sources
and acoustic scattering in ducted flows.
Advanced tools from system identifcation
were combined with high performance
computation of compressible, turbulent
flow. Both the power spectral distribution
of noise generated from turbulent fluctuations as well as the coefficients of the
acoustic scattering matrix were determined in a wide range of frequencies from
a single large eddy simulation. Moreover,
the uncertainty resulting from the limited
amount of time series data could be
193
quantified in terms of confidence intervalls for model parameters, which were
deduced by residual analysis. Application
of this approach to turbulent flames is the
topic of an ongoing joint research project
with Ecole Centrale in Paris.
In collaboration with visiting scientist
Luca Magri, post-doctoral researcher
Camilo Silva quantified the uncertainties
of thermoacoustic stability analysis with a
high-order adjoint formulation for the nonlinear eigenvalue problem that results from
the combination of a time-lagged model
for the flame dynamics with a Helmholtz
solver for combustion chamber acoustics.
This approach promises to confidently
assess the thermoacoustic stability of
configurations of applied interest with high
accuracy and efficieny.

Specification of fault-tolerant systems, verification and validation of safety-critical systems
n The focus of the Assistant Professorship of Safe Embedded Systems
(SES) in 2015 was to further develop methods and approaches in the
fields of specification and validation of safety-critical distributed appli
cations.
Design-to-Test

Validation by testing is a mandatory
procedure for safety-critical controllers.
However, the validation of a logic controller is often only considered in the later
phases of its development. Thus, if specific non-functional requirements related to
testing are not initially considered in the
specification models, this could lead to
the impossibility of validating the behavior
of a controller by means of testing.
Design-to-test approaches aim at improving the testability of controllers and
reducing the additional human workload
required to trustfully test critical logic
controllers.
In 2015, SES developed and implemented
a design-to-test approach for discrete
event systems. A demonstration software
has been developed for MATLAB Stateflow specifications.

The control of automated systems is
increasingly achieved by distributed
controllers. However, for critical systems
the global implementation needs to be
fault-tolerant. In order to achieve a desired
level of fault-tolerance and ensure high
dependability, two approaches can be
used: redundancy and reconfiguration
of systems. When these approaches are
combined, the research questions to be
regarded are as follows: How many subsystems may fail simultaneously without
losing complete control of the global
system? and How long can a subsystem
stay in its fail state before a reconfiguration is needed?
In 2015, SES investigated the implementation of redundant reconfigurable distributed architecture for automated guided
vehicles. This approach is using a serviceoriented architecture and has been
implemented on a microcontroller-based
architecture.

distributed architecture using

Supervisory Control Theory
Supervisory Control Theory (SCT) is a
model-based approach that permits to
automatically generate correct-by-construction supervisory controllers. Thanks to
SCT approach, which is using mathematically proved algorithms, generated controllers do not need to be verified anymore.
The designers can then focus more on the
requirements definition and the specification modeling. A set of specifications
permits to specify independently each
requirement (functional and non-functional
requirements, safety and liveness requirements, optimization criteria…). Then,
synthesis algorithms are applied on the
set of specifications and plants models
to generate a supervisory controller. The
obtained supervisory controller is then
guaranteed to be deadlock-free and maximally permissive (all the specifications
are fulfilled and only these specifications
are fulfilled).
In 2015, SES investigated two obstacles
for a wide application of SCT in industry.
First, while many industrial applications
use signals and dataflow to represent and

exchange sensors and actuator values,
the fundaments and most of the works
related to SCT use event-based modeling.
Secondly, most of the tools that use SCT
algorithms are not easily connected to
industrial programming tools, thus limiting
their application in industry. To cope with
these obstacles, SES investigated a signalbased SCT approach, and developed
a demonstration software for MATLAB
Stateflow models. This approach has
been successfully applied to our didactic
production system platform.

Perspectives for production
n In 2015, the Chair for Industrial Management and Assembly Technology
with its two locations in Augsburg and Garching considered in particular
the possibilities of how humans can be integrated into the objectives of
Industry 4.0. In addition, the further development of electro-mobility at the
production site Germany was specifically targeted.

Use of smart devices for human beings in industry 4.0
Industry 4.0
As a result of demographic changes, the
average age in producing companies will
continue to increase in the future. With
‘Industry 4.0’ the iwb not only means
the interconnection of systems, but also
how humans are safe in the production
environment and how they can effectively
use their skills and know-how.
Locations Augsburg and Garching In
close cooperation with the project group
‘Resource Efficient Mechatronic Processing Machines’ at Fraunhofer IWU in
Augsburg and four additional partners,
major milestones were reached over the
last few years, for example, with the project ‘InnoCyFer – Integrated Design and
Fabrication of Customer Individualized
Products in Cyber Physical Manufacturing
Systems’ supported by the German
Federal Ministry of Economics and
Energy (BMW) as the lead sponsor in the
DLR-sponsored project. The scientists are
working together to achieve the goal to
enable the integrated design and production of customer-innovated products.
This will be achieved through the develop-
198
ment of an open-innovation platform,
which would enable the integration of
the creativity and innovation potential of
customers in the product development
process. One important research content is the planning and control of an
autonomous production that is based on
cyber-physical systems, where the customer-innovated products will be produced.
It is linked directly to the open-innovation
platform to ensure that the customer is
always well informed of the feasibility of
his design, and at the same time receives
a delivery schedule and cost estimate.
The expected results offer companies a
very innovative business model with the
opportunity to position themselves on the
market with customer-innovated products,
and to strengthen Germany’s position as
a business location in the long term. With
the iwb Application Center Augsburg,
the Bavarian-Swabian location has been
benefiting for 20 years from the ‘Production Experts’. That way, the technology
transfer in Augsburg and surrounding area
will be ensured with the scientists there.
Assembly Technology and Robotics
The area of Assembly Technology and
Robotics addresses the assembly as the
last step in the value-creation chain within
the production process. Here, the costs
and quality of products are influenced in
a major way. Efficient assembly processes, innovative system technology and
assembly systems, and also the targeted
use of industrial robots are the key to a
cost-efficient production. The researchers
in the Assembly Technology and Robotics
group are therefore working on new
solutions to specific problems in these
areas. Significantly are also the current
trends in production. A large part of the
work is therefore orientated towards the
future area of electromobility and decen
tralized energy storage. In this connection,
a research line was created at iwb for the
production of lithium-ion battery cells
which offers a unique platform to research
the relationships between production and
product quality. Other significant developments are the ever increasing demands on
adaptability of assembly lines and robot
systems, as well as the topics related to
Industry 4.0. Starting with a comprehensive analysis, a thorough understanding
assembly and handling processes is
developed. Building on this, process
chains are generated and integrated into
innovative system concepts. Along with
that, economic and quality examinations
validate the applicability of the solutions.
Particular attention is being paid to the
industrial robot as a universal tool for the
automation of processes in production.

Production Management and Logistics
The research group Production Management and Logistics is working on projects
aimed at enhancing effectiveness and
efficiency of production. The research
scope covers three main fields of interest.
The first field comprises the design of an
effective change management in production, the management of production
technologies and facility planning. The
second field conducts research on the
efficient integration of human resources
in an increasingly digital and networked
production environment.
These fields are complemented by
research on optimization methods for
industrial application and on approaches
for efficient exploration of required data.
The group’s wide-ranging expertise in all
areas of production management and logistics stems from its fields of current and
199
former comprehensive research. Furthermore, the research group is equipped with
a real production environment through
the Model Factory for Lean Production
(LSP) and the Learning Lab for Humans
in Production. This environment supports
research, teaching and training in the
context of lean management and human
resources in production.

Development, simulation and experimental investigation of complex dynamical and mechatronical systems
n The Institute of Applied Mechanics is a leading research center in the
dynamics of mechanical and robotic systems. The core of its activities
focus on the development of novel simulation and experimental techniques
for efficient analysis of complex structural dynamics, and on the design,
construction and control of advanced robotic machines.
The research is organized in three focus
areas: Robotics and Mechatronics, Dynamic
Simulation and Numerical Techniques, and
Experimental Dynamics. Each research

group bundles specific expertise, monitors
international advances and actively
discusses the future research directions.
Robotics and Mechatronics
Mechatronics is the combination of
mechanical, electrical and informatics
systems. A focus of this field lies on the
actuation of multibody dynamical systems
and vibrating structures in order to achieve
specific functions. One example of such
systems are robots which are investigated
at our institute.
Our institute has a long tradition in
designing, constructing and controlling
robots for novel applications. Based on
our experience in autonomous legged
robots, our institute has developed a high
performance humanoid robot (LOLA) in
recent years.
Working in an interdisciplinary team, we
combine techniques from informatics,
electronics and mechanics to advance the
overall system performance on real world
walking scenarios. Our focus lies on the
development of model-based methods
for biped walking which are not restricted
to one specific robot or scenario. Current
research projects include environment recognition and modeling, trajectory planning
and walking control.
The institute’s expertise in robotics has also
been applied to other fields: In September
2014 the EU-project CROPS was successfully finished by developing in collaboration
with an international consortium the world’s
first autonomous harvesting robot for
sweet pepper in greenhouses. Its core
component was created at our institute; the
multipurpose, modular redundant manipulator arm. With up to 9 degrees of freedom,
it is specifically designed for harvesting
sweet peppers, apples or the precise
spraying of grapes. In addition to the opti-
LOLA, the humanoid robot
mization of the kinematics and mechatronic
design, our research also included motion
planning based on tactile feedback for
operations in cluttered environments such
as greenhouses.
Another area, in which our institute collaborates with the Department of Orthopedics
and Sports Orthopedics, is the investigative
manipulation of biologic joints. An experimental test rig has been developed, which
combines adaptive trajectory planning and
compliant motion control schemes at high
frequencies (4000 Hz) to actuate biologic
joints utilizing a robotic arm and thereby
analyze their spatial biomechanical behavior.
This technique aims at improving the design
of joint replacements (endoprosthesis).
Furthermore, the robotics group has proven
its worth at the European Robotics Challenge; our institute won the first stage by
developing a powerful software framework
for the autonomous operation of a mobile
robot platform in an industrial scenario.

Dynamic Simulation and Numerical Techniques
Designing and optimizing high-tech
systems necessitates accurate and efficient
modeling. The expertise and research focus
of the institute is mainly in model reduction
aspects, parallel computing strategies
and numerical techniques simulating
the dynamic of contact between bodies,
including lubrication through films.
To obtain accurate dynamical system
models multiphysical effects need to
be included for instance to account for
lubrication films (elasto-hydrodynamics), for
vibro-acoustic interaction or for electromagnetical coupling.
Models used to analyze the dynamics of
structures often contain several millions of
degrees of freedom. We develop methods
to characterize the dynamics of linear and
non-linear structural models with only a
reduced set of unknowns so that models
can be used for optimization, design validation or as flexible components in multibody
dynamic simulations.
In order to use the power of modern
multiprocessor computers, we develop
solution algorithms based on the paradigm
of domain decomposition; if the problem
is partitioned in different domains (regions
of a structural model), the solution is found
by iterating on the interface solution while
STÄUBLI RX90B manipulator
for investigative manipulation of
biologic joints
the behavior in the domains are computed
independently by different processors.
We improve those methods to make them
robust for real-life problems that include for
instance high heterogeneities or complex
dynamics.

Experimental Dynamics
Dynamic testing is regularly performed
in our labs in order to validate models
and test constructions. In addition
experimental dynamic techniques are
part of our research where we improve
identification methods. Within the project
KonRAT (Rocket Engine Components
for Aerospace Transport Systems) liquid
oxygen turbo pumps are analyzed. Techniques to characterize the rotor dynamics
as well as the dynamic behavior of seals
and bearings are developed; combining
reduced component models, validated
on several test rigs, the influences such
as seal instabilities and bearing effects
on the turbo pump rotor system can be
determined. Another important research
topic is experimental substructuring;
based on the measured dynamics of
components, a full model is built numerically by specific assembly techniques.
Obtaining an accurate assembled
numerical model from measured components requires special measurement
techniques and signal processing steps.
With these techniques we enable novel
methodologies to investigate for instance
noise and vibration propagation in cars.
In our lab we test substructuring strategies on a small wind turbine as part of an
206

international benchmarking activity for
substructuring.
Sustructuring ideas are also used in
so-called real-time hybrid testing. This
special hardware-in-the-loop technique
numerically simulates structural components for which models are available,
and exchanges in real-time forces and
displacements on the interfaces with a real
hardware component in the lab. In such
an approach components can be tested in
real conditions, where the dynamic interactions with the full system is accounted
for. We develop special computational
and control strategies based for instance
on adaptive feedforward compensation

Technology-driven thermo-fluid dynamics research
n Our research guide line is the proposition that scientific research in an
engineering school should be focused on problems with high technological relevance. A key to realizing our mission is the close cooperation
with industry in general and in particular with partners who – developing
their top-class global products at the leading edge of technology – have
encountered barriers that might be overcome by fundamental research.

Our partner industries are optimizing their
technologies towards a lower carbon footprint, integration with renewable power
sources and environmental compatibility.
Their research needs are reflected in our
four research groups. The increase of fuel
efficiency and operational flexibility at low
pollutant emissions pursued in the power
industry requires fundamental research in
the areas of combustion fundamentals,
emissions and reliability and combustion
instabilities. Pollutant reduction and fuel
flexibility development in large reciprocat-
ing engines require basic understanding
of multi-phase phenomena. Alternative
thermal comfort systems are explored to
improve the efficiency of mobility applications.
The appreciation of this approach in the
technical community is reflected by the
six Best Technical Paper Awards our
research group has received from the
ASME International Gas Turbine Institute
Combustion and Fuels Committee during
the past fifteen years.
Combustion Fundamentals
Investigation of the correlation
between heat release and OH*
radiation
Turbulence-chemistry interaction is the
common research topic of this work group
with applications from scramjets to reheat
combustors as well as flame acceleration
and deflagration-detonation transition in
confinements and reciprocating engines.
The group shares common numerical and
experimental approaches to describe the
processes of unsteady combustion.

Combustion Emissions and Reliability
Alternative fuels are a challenge for
gas turbine combustors with respect
to combustion emissions, stability,
autoignition and flashback safety. This
work group investigates the fundamental
processes and develops rules applicable
to new combustor designs with respect to
low-emission fuel-flexible operation.

Combustion Instabilities and Noise
The strong coupling of acoustics and
heat release in confined flames leads to a
feedback loop which can result in violent
combustion instabilities. These are a
threat for gas turbines, rocket motors and
other combustion devices because they
result in substantial pressure oscillations,
structural vibrations and increased heat
transfer. Combustion instabilities reduce
the lifetime, limit the operation range or
even lead to severe damage of combustion systems. This research group uses
numerical and experimental techniques on
a wide range of topics from combustion
instability like flame-to-flame interaction,
prediction of combustion instability, active
instability control and flame noise.

R&D in sports technology combining engineering, sports science and computational methods
n Our main ambition in 2014-15 was to submit two major research proposals for funding; one on mechatronic ski bindings at the German Research
Council (DFG) and the other (in collaboration with our TUM Institutes of
Automotive Technology and Metal Forming and Casting) on innovative
production technologies to receive financing by the Bavarian Research
Foundation.

From our 2015 research activities four
highlights are worth mentioning:
n ispo Brand New Award for our start-up
‘tripstix’ in the category Hardware
Summer.
n Successful launch of heart rate control
for electric bicycles.
Towards Better Performance with
Optimized Sport Equipment
Improving the performance in both
top level and leisure time sports is one
motivation for our work. The focus is on
optimizing the energy transfer between
athlete and equipment and on reducing
the inherent energy loss. On the equipment level we try to achieve this by
n improved fitting to the individual
(i.e. golf shaft),
n better weight to stiffness ratio
(i.e. bicycle frame),
n using energy storage & return effects,
n optimized heat- and moisture management of sports garments (i.e. new infills
for down jackets).
One example of our work in this field
in 2015 is the patented Tripstix design
for highly functional, inflatable stand-up
paddle boards. It uses a new dual chamber system technology called ‘VacuuAir’.
A vacuum chamber filled with granule
encloses a high-pressure chamber,
offering additional stability. This allows
a board to be designed with the exact
shape of a regular surfboard – including
thin rails, a delicate nose, and a stable tail.

With its dual chamber system, the board
is extremely stable and safe. It will keep
afloat even when punctured.
Another optimization related to sports
materials has been done on a racing
bicycle frame. Its tubes are made of
bamboo connected with carbon fiber
composites. An extended test program
was performed to improve its strength,
stiffness and its fatigue behavior with the
result of an optimized lay-up design.
Understanding the Interaction between Athlete,
Equipment and Environment
Instrumented skier with dynamometers, goniometer,
differential GPS and inertia sensors
This important research field in sports
engineering has also been part of our work
in 2015. We continued a research project
on behalf of endoGAP clinics which is
motivated by the increasing number of
total hip replacements in OECD countries.
The majority of these patients regain full
mobility and formerly active people like to
go back into sports.
The aim of the project was a qualified
estimation of hip joint loads in alpine
skiing, confirmed by reliable field trial
measurement data. The questions to be
answered: Should their skiing continue to
be allowed without reservation and which
recommendations for limiting the acceptable skiing manoeuvres should be given?
Attaching and wiring the inertia full
body motion capture system
More Safety with Improved Protection Gear
Related 2015 Project
In alpine skiing knee injuries remain the
major challenge for improved protection
equipment. Systematic analysis of injury
situations and human anatomy suggest
that mechatronic ski bindings may provide
the solution. Although patents for mechatronic ski binding concepts were submitted
in the early eighties, no commercial
product has appeared on the market.
The main reason is that the algorithm that
controls such mechatronic bindings needs
a comprehensive understanding of the
complex interaction between the external
loads and those of the different structures
of the knee. An artificial lower leg including
an instrumented knee has been realized
and combined with a load simulation
device. This allows systematic investigation of any combination of external forces
and moments and measuring the resulting
tension in the critical knee ligaments.

Less Effort and More Fun Through Technical Support
tive Technology (Professor Lienkamp) we
have successfully implemented a control
circuit that uses the rider’s heart rate to
manipulate the electric power support of
this new type of lightweight vehicle, called
‘QuadRad’.
Prototype ‘QuadRad’, a new category of electric driven lightweight
vehicle, on the test bench
Electric bicycles are becoming more
important as a mean of transportation. One
of the biggest issues regarding electric
bicycles is their inaccurate prediction of
the residual range. For better prediction
it is essential to gain detailed knowledge
of the cyclists’ fitness, the type of electric
bicycle and the environmental resistances.

Our research can be divided into four
areas: Power Plant Technology, Renewable
Energy, Modeling and Simulation, as well
as Measurement Technology. We cooperate with research institutions and industrial
companies on a number of national and
international research projects. The
expertise of the institute is also reflected
in the large number of operated testing
facilities, and in the utilized measurement
technologies. The mechanical workshop,
the electronics laboratory, and the chemical
laboratory are also essential parts of the
experimental operation at our institute.
Key competences regarding modeling and
simulation are CFD simulations of combustion and gasification processes, entire
process simulations, burner design, form
optimization of blade and seal geometry,
as well as the simulation of deposition and
slagging tendencies.
Furthermore, a Siemens GuD Simulator
(SPPA-T3000) can be found at the Institute
for Energy Systems, which makes it
possible to simulate various power plant
processes, and to test the control system
of power plants.
Power Plant Technology
Pressurized entrained flow reactor
With a stronger presence of renewable
energy sources in the power grid,
combined cycles and coal-fired thermal power plants are subject to more
frequent and larger load changes. The
evaporator as a component in thermal
power plants and its dynamic behavior is
of great interest for flexible power plants.
To investigate the evaporation process
under dynamic conditions, an evaporator
test rig is being installed at the institute.
Further test rigs include an oxyfuel
combustion chamber and entrained flow
reactors. The oxyfuel combustion of coal
is one of the three main research routes
for the development of coal-fired power
220
plants with CO2 capture and storage
(CCS) systems. The aim is to develop and
demonstrate combustion and boiling systems on a commercial scale. Coal power
plants on the basis of IGCC technology
(integrated gasification combined cycle)
mainly use entrained flow gasifiers and
offer the advantage of high efficiency
and the opportunity for effective CCS.
The primary objective of the work at the
institute is to lay the necessary foundations for the long-term development of
future, highly efficient high-temperature
gasification processes with integrated
hot gas purification and optional CCS for
IGCC power plants and processes for the
development of synthetic fuels. Further
projects investigate the development
of a corrosion reduction concept and
the potential of the SNCR process, in
order to reduce the emissions of waste
combustion facilities. The SNCR research
focuses on ammonia injection in substoichiometric zones.

Renewable Energy
The use of biomass for electricity and
heat production has moved increasingly
into focus. In the biomass work group
the goal is to investigate and to solve
problems and limitations that arise in the
thermal use of biomass. Key aspects are
the reduction of emissions and unburned
materials, trace elements like sulfur and
chlorine compounds, as well as alkalis
and particles. Together with Suncoal
Industries GmbH, focusing on the process
of hydrothermal carbonization (HTC), the
conversion of biochar in an entrained
flow gasifier is investigated. A procedure
for the treatment and methanation of the
product gas from a biomass gasifier is
developed as well. The processed gas
has to meet the criteria for integration into
the natural gas grid. Furthermore, within
the framework of the SOFCOM project,
the ability to use solid oxide fuel cells
(SOFCs) as an efficient means of biomass
generation in combined cooling, heat, and
power facilities is investigated. The focus
lies on decentralized facilities for the use
of locally produced biomass.
Projects
n FLUHKE – Entrained flow gasification
with biochar
n FNR – Thermal use of biomass in
high-temperature processes
n SOFCOM – Solid oxide fuel cells
n SNG – Decentralized production of
synthetic natural gas from biomass
SNG test rig
Modeling and Simulation
Modeling and simulation of solid fuel conversion play an important role in several
projects mentioned above, e.g. HotVeGas,
RELCOM and NOx reduction. Computational fluid dynamic (CFD) simulations are
applied in order to gain a more detailed
understanding of several combustion and
gasification processes. Furthermore, entire
process simulations aim at evaluating
the complete power plant system and
possible synergies. As the flexibility of
power plants gets into the focus of the
operators – in addition to efficiency and
economy – the interaction of power plant
processes during dynamic operation
is investigated by means of dynamic
simulations of power plants. An improved
process understanding helps to develop
better operating strategies and optimized
power plant configurations. Two different
power plant types are investigated: combined cycle power plants and coal-fired
power plants. Also the economic use of
waste heat is a focus of research. The use
of waste heat at low temperatures with
organic Rankine cycles (ORC) is examined
at the Institute by means of process
simulations.

The Institute of Machine Elements, also
known as ‘Gear Research Centre’ (FZG),
is an established internationally renowned
research centre for gears and transmissions. The development of methods and
tools for reliable determination of fatigue
life, efficiency and vibration characteristics
of gears and transmission elements is
the primary focus of research activities at
FZG. FZG has state-of-the-art facilities for
the examination and testing of different
machine elements – such as gears, synchronizers, clutches and rolling element
bearings.
The research projects of FZG range
from theory-oriented basic research to
application-related work. The projects
are financed and supported by different
organisations. A large number of these
projects are initiated, financed and
supervised by the Forschungsvereinigung
Antriebstechnik e.V. (FVA), usually together
with the Arbeitsgemeinschaft industrieller
Forschungsvereinigungen (AiF). Other
important research partners include the
Deutsche Forschungsgemeinschaft (DFG),
the Bayerische Forschungsstiftung, the
Deutsche Wissenschaftliche Gesellschaft
für Erdöl, Erdgas und Kohle e.V. (DGMK),
the FVV or the Stahlforschung. In addition,
many application-oriented projects are
requested and commissioned directly by
industry.
Our education lecture series and exercises
in machine elements represent the basic
training of mechanical engineering. In
the lecture, the students learn to select
machines and machine elements properly, to design them and to calculate
their properties. This knowledge is then
practically applied to design and calculation examples within the lecture-related
exercises. A very important aspect of this
is that the students learn to communicate
in the ‘engineer’s language’ – with sketches and drawings. Practical relevance
and topicality are also an important criteria
for lectures with special subjects. Last but
not least, this is ensured with lectures by
executives from industry.
Research Components
The focus of research activities is the experimental and theoretical examination of
gear components and drive systems.
Cylindrical Gears
Back-to-back gear test rig
(a=91.5mm)
224
Cylindrical gears are the most common
transmission types. The fatigue life of cylindrical gears is limited by pitting, micro-pitting, scuffing, wear, tooth root breakage
or tooth flank breakage. The basis for the
experimental examination of such gear
damage is the standard FZG back-to-back
gear test rig, which was developed by FZG
and is used all over the world.
The described types of damages, as well
as material, lubricant and efficiency examinations for external and internal gearings,
can thereby be carried out very efficiently.
In addition to sufficient load-carrying
capacity and good noise characteristics,
research is increasingly focusing on the
efficiency performance of gears.

Bevel and Hypoid Gears
Bevel gears are used for power and torque
transmission between non-parallel axes.
The main application field of bevel gears
is the automotive industry. However, bevel
gears are also used in large numbers in
train and ship propulsion, as well as in
industrial gearboxes.
The FZG hypoid gear test rig was
developed for life tests on bevel and
hypoid gears. Like the FZG back-to-back
gear test rig, this rig operates on the
principle of the mechanical power circuit.
These test rigs are used for the examination of tooth root and tooth flank loadcarrying capacity, as well as for hypoid
gear oil tests.

gears causes higher power losses with
increasing transmission ratio. With torque
measurement shafts, efficiency tests for
every operating condition can be performed with these test rigs. The tooth root
load-carrying capacity of worm gears can
be determined within pulsator tests.
Left: worm gear test rig
Above: worm gear
Worm Gears
Worm gears offer the possibility of
realising high transmission ratios in only
one stage. Thus a considerably high
axial sliding occurs, leading to reduced
efficiencies. Due to the large overlap,
worm gears have low noise and vibration
levels. Self-locking and self-braking are
possible by appropriate choice of the gear
geometry. The application of worm gears
as power gearboxes is mainly limited by
wear, pitting or limited efficiency. Other
material combinations than the conventional combination of steel and bronze are
more endangered by scuffing.
Both electrically and hydrostatically loaded
test rigs are available for the determination
of sliding wear, pitting and scuffing of common worm gear bronzes, as well as brass,
grey cast iron and spheroidal cast iron.
The results are represented as specific
wear or scuffing damage in correlation
to the drive torque or as pitting growth
over the number of load cycles. The

Synchronizers
Above: synchronizer
Right: ZF/FZG SSP-180 test rig
In vehicle manual and DCT transmissions,
gears are changed by the actuation of
tooth clutches. Synchronizers are used
to realise equal rotational speed in the
tooth clutch, which is necessary for
convenient gear shifting. The requirements
for synchronizers are application-specific
and cover a wide spectrum. Besides a
high torque transfer capability and related
high energy and power density for the
friction material and the lubricant, low
wear and high long-term stability of the
friction behaviour, as well as convenient
gear shifting are important development
objectives.
Examinations of friction, wear and service
life behaviour of synchronizers are carried
out with the FZG standard synchronizer
test rig ZF/FZG SSP-180.

Multidisc Clutches
Above: multidisc clutches
Right: KLP-260 disc clutch test rig
Oil-lubricated multidisc clutches and brakes
are used for example in automatic transmissions for gear shifting and for frictionally
engaged power transmission. Multidisc
clutches are characterised by a high power
density in a compact design. They can
be actuated under load and difference in
rotational speed because the torque is
transmitted by friction. Functional and service-life behaviour depend to a large extent
on the load and the friction system. The
mechanical and thermal load of the clutch
which occurs during the shift operations
are not constant in practical application but
vary due to different shifting conditions.
The friction, wear, drag loss and service-life
behaviour of oil-lubricated multidisc clutches are examined with the FZG multidisc
clutch test rigs. Accordingly, an evaluation
of the influences of friction material, groove
pattern, volume of oil flow, lubricant and load
on friction, wear and drag loss behavior is
possible.

Rolling Element Bearings
Rolling element bearings are used for the
guidance of axles and shafts, whereby
they absorb radial and/or axial forces and
226
simultaneously allow the rotation of the
shaft or of the mounted components. Thus
the friction and power loss should be kept
to a minimum. With the bearing power
loss test rig of the FZG, the bearing losses
under load or no-load can be measured
for various bearing arrangements. These
results then can be used for the validation
of the common calculation methods for
the determination of the bearing losses.
Taking bearing losses in the test rig into
account, the resulting gearing losses can
be determined.
Wear and frictional behaviour of bearings
depend on the lubricant used. Evaluation
of lubricant samples is possible on the
roller bearing lubricant test rig FE-8,
according to DIN 51819, for the determination of anti-wear capacity.

Research Topics
In addition to the investigation of transmission components, the FZG also focuses
on basic and comprehensive research topics of transmissions and machine
elements in general.
EHL-Tribological Contact
For gear drives, the ratio of sliding to
rolling along the path of contact is variable. Basic investigations on rolling and
sliding contacts are performed on twindisc machines, which make it possible
to adjust any slide-roll ratios at different
rotational speeds. Local measurements of
pressure, temperature and film thickness
can be performed by means of thinfilm
sensors. Theoretical consideration and
calculations (EHL theory) supplement the
experiments.
In classical hydrodynamics, the contact
surfaces are assumed to be rigid. The
lubricant wedge formation only depends
on the lubricant and the speed ratios of
both contact partners. This simplification
is not possible for high pressures. The
flexible deformation of the contact area,
as well as the viscosity change in the
contact zone on the basis of differences in
temperature and the high local pressure,
can no longer be neglected. These effects
are recorded on computed distributions
of pressure, temperature and lubricant
EHL film thickness distribution
film thickness in the contact by applying
the EHL theory. Complex simulations can
be used to calculate them numerically.
Consequently main shear and octahedron
stresses below the surface of the two
contact partners can be determined.

Load-Carrying Capacity
Scuffings on a spur gear
A large part of the research topics deals
with the load-carrying capacity of the
components cylindrical, bevel, hypoid and
worm gears, as well as multidisc clutches, synchronizers and rolling element
bearings. For gears, fatigue lifetime is
often limited by pitting, micropitting, wear,
scuffing, tooth root breakage and tooth
flank fracture.
The results of many research projects
at FZG are gained from theoretical and
experimental investigations. In order to
develop a method, simulation models
are usually developed and validated by
extensive experimental studies.
Exemplary project
n FVA project ‘Gleitgelagerte WellenLager-Systeme’
Dynamics/NVH
Internal additional dynamic forces, which
change tooth stress and affect noise
behaviour of the transmission, occur in
running transmissions. The NVH behaviour
of gears is becoming more and more
important due to increased customer
expectations regarding noise. The additional dynamic forces must be considered
during development of high-performance
transmissions. Experimental and theoretical investigations are used to determine
these additional dynamic forces and to
develop and improve analytical calculation
models for the simulation of excitation and
vibration behaviour.
Efficiency
In addition to sufficient load-carrying
capacity and good noise characteristics,
research is increasingly focusing on the
efficiency performance of gears. Efficiency
investigations on oil- or grease-lubricated
cylindrical gears are carried out with the
FZG efficiency test rigs under different
operating conditions.
In parallel, oil distribution and no-load
losses are determined by means of CFD
simulations and validated with results of
experiments.
Efficiency test rig
Fatigue Life Analysis
In the context of fatigue life analysis, the
fatigue life of gears can be determined
under time-varying operating conditions,
e.g. for vehicles and industrial applications. Load, temperature and speed
spectra, which are determined from
real operating conditions and modified
228
for operation in the test rig, are used to
investigate this fatigue life. In pulsators or
back-to-back gear test rigs with hydraulic
load application the load can be varied
during the operation according to these
load spectra. Thus fatigue life investigations are possible.
Alternative Materials, Composites and Coatings
Plastic gears can be advantageous in
specific transmission applications. The
high material damping has a positive effect
on the noise behaviour, the low mass and
mass inertia can be distinguished in transmissions, which are subject to high accelerations. The main advantage of plastic
gears is their dry run capability. This makes
them ideal for applications e.g. in the field
of medical technology, food processing
or the printing industry, where lubrication
is not possible for functional or hygienic
reasons. High friction losses in the dry run
capability of plastic gears limit the transmittable power from a thermal viewpoint.
Loss-optimised gears exhibit significantly
lower friction losses by concentrating the
meshing around the pitch point.
A composite structure, in which the teeth
are made of steel and the wheel body is
made of plastic, combines the advantages
of steel and plastic gearings. Besides
increasing the lightweight design potential,
it is possible to manipulate the dynamic
system behavior favorably by using
composite gears. Moreover the tribological properties and the flank load-carrying
capacity of steel gearings can be optimised by using extremely hard coatings
e.g. amorphous carbon coatings. The
impact of such coatings on efficiency and
fatigue life is investigated at FZG.

Drive Systems/Electromechanical Drives
The demand for sustainable mobility
requires the development of innovative
drive systems with optimised energy
management. One opportunity of
realising this is represented by hybrid
drive systems, which are a combination
of several different power sources and
aggregates. The research into hybrid
drive systems at the FZG has been carried out since 1993. The main topics are
conception and simulation of hybrid drive
systems. For the development of alternative drive systems, special simulation
tools have been engineered to evaluate
the properties of drive concepts. The aim
of complete vehicle simulations is the
determination of fuel economy and driving dynamics for different driving cycles
and manoeuvres. A variety of configurations and parameters must be identified
for concept studies; especially high
requirements are necessary with respect
to the computational time of simulation
models. Nevertheless a high degree of
flexibility and expandability must be given
in order to detail the vehicle models for
further analysis.
A special highlight in this field is the
‘Active Differential’. The lightweight,
compact and efficient system with torque
vectoring function in the drive train of
Visio.M (TUM electric vehicle) offers a high
potential for increasing driving dynamics
and recuperation performance.
The aim of the project Speed2E is the
development, optimization and construction of a high speed powertrain for
electrical automotive applications, which
allows a tripling of motor speed. During
the project aspects like efficiency, tooth
excitation and vibration transmissions are
considered.

Engineering and operation of intelligent, reconfigurable, distributed cyber-physical production systems
n In 2015, the Institute of Automation and Information Systems (AIS)
focused on analyzing, establishing and improving novel methods, approaches and tools to address the challenges that result from the increasing
demand to produce customer-specific, individual products in the machine
and plant manufacturing domain.
Therein, innovative approaches for
Industry 4.0-capable systems have been
and are being developed to improve
both the engineering and the operation
of cyber-physical production systems.
Among others, technologies and methods
applied at AIS are agent-based and
service-oriented approaches as well as
modeling approaches – both semi-formal
and formal – to provide novel concepts
for designing and operating intelligent,
reconfigurable, distributed cyber-physical
production systems. Especially methods
and technologies from the computer
science domain are used and adapted to
address the challenges in automation and
in the machine and plant manufacturing
domain. Moreover, taking the interaction
with humans and machines into account,
the methods and approaches developed
at AIS are analyzed and evaluated in realworld scenarios and together with experts
from industry.

Open research demonstrator „myJoghurt“
(Starterkit available from http://i40d.ais.mw.tum.de)
The ever-increasing complexity and
dimensions of automated production
systems in industrial automation require
a high degree of flexibility and intelligence
in and among system components.
Hence, one aspect being addressed by
AIS is to explore the advantages of such
intelligent, reconfigurable and distributed
systems contrary to their disadvantages,
e.g. the extended need for communication.
Therefore, at AIS, notations, methods
and tools are developed for the design of
agent-oriented automation software for
machines and production plants in both
the manufacturing and process automation domain. By that, the design, implementation and operation of distributed,
intelligent cyber-physical production systems can be simplified, comprehensibility
can be increased and, thus, acceptance
in industry can be enhanced. In 2015, two
233
novel research projects (namely aComA
and iSikon) were established that address
the need for flexibility and reconfigurability
in the logistics domain. Moreover, the joint
demonstrator ‘myJoghurt’ was extended
together with three further German institutes – thereby enlarging the demonstrator
towards eight participants. Furthermore,
since 2015, ‘myJoghurt’ is contained in
the ‘Landkarte Industrie 4.0’*, which has
been initiated by the ‘Plattform Industrie
4.0’ initiative. Besides others, together
with international robot companies, the
same architecture and platform was
applied for a collaborative production.
Using simple scenarios, the coupling of
locally distributed production systems in
an automatic and dynamic manner can be
demonstrated using ‘myJoghurt’.

Besides improving the operation of
Industrie 4.0-capable systems, one major
area of interest for AIS is the engineering
of automated production systems. Therein,
AIS investigates concepts and methods
towards the model-based development
of such systems – both in the (discrete)
manufacturing engineering domain and
in the (continuous) process engineering
domain. A special focus is put on the
interdisciplinary character of the design of
industrial automation systems as well as on
increasing the transparency and handling
the complexity throughout the workflow of
automation systems design and operation.

As one major success in 2015 – not only
for AIS as coordinator, but also for the
entire research team – the DFG approved
the extension of the Collaborative
Research Center (CRC) 768 for a third
funding period of four years. Moreover,
AIS was able to establish further research
projects within the second funding period
of the Priority Programme (PP) 1593. In
addition, concepts for the integration
of energy aspects with the modeling of
the operating performance (behavior)
of production systems and automotive
systems are explored (cf. research project
ProMES). Therefore, different modeling
languages are investigated and adapted
for these different classes of mechatronic
systems and corresponding editors and
tool environments have been developed.
For the coupling and synchronization of
heterogeneous models, model transformations as well as formal methods for
consistency checking have been investigated and successfully applied. Concern
ing the transfer of research results into
industrial applications, a major outcome
of this field of research is the successful
realization of approaches for model-based automation software development,
code generation, and model-based
debugging (e.g. within the completed
projects ZuMaTra and MoBaTest) as well
as software testing inside a development
environment for automation software that
is widely used in industry. As one core
aspect of industrial automation software,
a working group ‘Modularity, Variant
and Version Management in Industrial
Automation’ was established together
with companies in the packaging, wood
processing and automotive domain. Our
core demonstrator – the Pick and Place
Unit – was extended in 2015 to address
further, industry-relevant aspects such
as safety, modes of operation and novel
communication technologies.

Human-Machine Interaction as well as Data
Integration and Processing to Support Humans
This field of research addresses the
design and evaluation of human-machineinterfaces (HMI) for operators as well as
engineering support systems. The research field concerns supporting the operating personnel in training, commissioning,
process monitoring, process optimizing,
and diagnosis by means of appropriate
visualization methods of process and
message data during the operation phase
of technical plants. The current trend in
industry is to replace the classical 2D
visualization systems in control rooms
for process monitoring and operation by
new visualization technologies such as 3D
visualization as well as augmented reality
and their visualization on mobile devices.
Today’s challenges cover the extraction of
beneficial information from the rising flood
of process data to e.g. detect faults. This
information is collected by data aggregation and data analysis from many different
data sources. Fault characteristics are not
only characteristics indicating a fault, but
also symptoms that indicate causal impact
of a fault within a system. Based on this
analysis the system can provide recom-
mendations to the operator on how he has
to intervene in the process. AIS, therefore,
not only investigates scalable integration
concepts for aggregating and analyzing big
industrial data sets (cf. project SIDAP), but
also visualization and navigation concepts
(cf. SFB 768 D2) to support stakeholders in
the industrial automation domain.

Process and material qualification for metal forming, blanking and casting
n The Institute of Metal Forming and Casting focuses on the three production processes: casting, blanking and metal forming. In 2015 over
40 scientists worked at the institute on research projects which vary from
fundamental research to industrial application.

was the realization of a continuous Cu-Cu
composite casting process. During the
year an active exchange of cultural and
scientific ideas was held with our two

Casting
The research group ‘Casting’ focuses on:
n Molding materials
n Residual stress analysis and material
characterization
n Tooling technology for (high pressure)
die casting
n Continuous and composite casting
In the casting industry, especially in the
area of light metal casting, inorganic binder systems replace the existing organic
binders. This provides economic and
environmental advantages but requires
a rethinking of well-known processes. A
new core-blowing machine was installed
in 2015 what gives the possibility of im
proving the state-of-the-art manufacturing
technology for cores. In combination with
the 3D printer the whole production process from prototyping to series production
is represented and investigated at the
institute.
Another trend in the automotive industry
is the use of die cast structure parts
replacing sheet metal parts. Due to their
highly complex geometries extensive
research in the field of tool design is
required and was carried out in several
projects.
Core blowing machine Loramendi SLC2-25l
The research in the fields of continuous
casting and composite casting focuses on
the development of continuous compound
casting processes which saves production
steps, energy and material. Furthermore
basic studies on the formation of compounds of highly different metals, such as
copper and aluminum are done.
The neutron source FRMII situated near
the institute offers enormous possibilities
in materials science. For instance the
development of residual stresses during
the cooling process of a cast part or the
phase transformation kinetics in austempered ductile iron is investigated in situ
using neutron diffraction.

Blanking
The research group ‘Blanking’ focuses on:
n Enhanced understanding of blanking
processes
n Wear of blanking tools
n Optimization of materials and part
quality
n Processes with analogies to blanking
Cutting tool (top and bottom part)
240
In the sheet metal industry, blanking
is a widely used process in all kinds of
enterprises. To ensure the economic and
technological progress, fundamental and
industrial research in this field is necessary.
The application of electric drives in the
automotive industry is constantly rising.
To achieve a decreased energy consumption the whole production process chain
of electric sheet metal has to be investigated. The influence of different blanking
parameters like tool wear or cutting clear
ance on the electromagnetic properties
is widely unknown. Hence this research
project should point out optimized
process parameters for the production
of more sustainable electric drives. To
improve the prediction quality of embossing simulations, a new approach which
considers the influence of the embossing
line geometry on the material model is
investigated. In order to predict the slug
pulling the forces acting on the slug will
be investigated with a stamping tool
containing extensive sensors. The slug
sticks on the punch face or is pulled out
mainly due to the burr clasp, adhesion/
cohesion with lubricant and vacuum
during return stroke. Once the danger of
slug pulling can be estimated at a given
set of process parameter, the available
methods for preventing slug pulling
can be applied in the early stage of tool
development. Another project focuses
on how to diminish wear on the tools of
a stamping process by specific voltage
application. Under the influence of lateral
forces during the stamping process, the
die clearance is alters, which can give
rise to wear. Hence another project is
dealing with the issue of how to increase
the rigidity of the stamping tool to prevent alteration of the die clearance. Burrs
on blanked products are undesirable. For
this reason an innovative tool concept
is developed, which leads to burr-free
sheared edges. In the automotive industry highly-tensile steels are increasingly
used. For the improvement of the edgecrack sensitivity, especially for these
steels broad research efforts are made.
The blanking of organically coated metal
sheets is widely reviewed particularly
due to the influence of oxidative wear of
the tools and corrosion-resistance of the
sheared edges.
Projects
n Burr-free sheared edges (AiF)
n Development of a software-tool for the
robust design of the shearing process
of metallic multilayer materials without
additional lubricant (DFG)
n Dry punching of coated metal sheets
(AiF)
n Improvement of the formability of
sheared egdes of iron-manganese
metal sheets through optimized
punching parameters (FOSTA Stahl
anwendung e.V.)
n Influence of process-related altering
die clearance on tool wear (FOSTA
Stahlanwendung e.V.)
n Lubricant-free forming by affecting
thermoelectric currents (DFG)
n Cause and prediction of slug pulling

n Process enhancement for the application of high-tensile steels (AiF)
n Production of energy efficient electric
sheet metal parts (DFG – FOR1897)
n Geometry and feasability prediction
of sheet metal parts with embossings
made of high-strength and ultra-highstrength steels (FOSTA Stahlanwendung e.V.)
Metal Forming
The research group ‘Metal Forming’
focuses on:
n Qualification of materials
Quasi-static material properties
Strain rate sensitivity
Temperature sensitivity
n Qualification of processes, tools and
machinery
Planning processes
Forming tools
Forming machines
The understanding and optimization of
forming processes is the topic of this
research group. Besides wide-spread
processes such as deep drawing or
bending, also joining and driving processes are studied. Almost every project
includes finite element simulations to gain
deeper process insight and to improve the
processes itself. The understanding of the
material behavior and the use of adequate
material models is essential for the successful simulation of forming processes.
Therefore, the qualification of materials
is a key topic of the research group.
Depending on the process, also the strain
rate and temperature sensitivity have to be
included in the material model in addition
to the quasi-static material properties.
One exemplary project is the prediction
of formability after linear and non-linear
forming history in sheet metal process
Sheet metal testing machine BUP1000
simulation. The common criterion in
industrial applications is the Forming Limit
Diagram (FLD), which is standardized in
ISO 12004-2. It is only applicable for linear
strain paths. However, in most industrial
experimental and simulation cases nonlinear strain paths occur. To resolve this
problem, a phenomenological approach
was introduced, the so-called Generalized
Forming Limit Concept (GFLC). The GFLC
enables prediction of localized necking
on arbitrary non-linear strain paths. For
this concept a database, which consists
Draw bead tool
Biaxial testing machine
of different combinations of pre- and
post-forming is required. To address the
experimental effort the institute acquired
a universal sheet metal testing machine
BUP 1000, funded by the German
Research Group (DFG). Furthermore,
mapping multi-linear strain paths appears
highly complex in practice and involves a
range of testing equipment, e.g. different
specimens, testing machines and tools.
One possibility to overcome this extensive
effort is to use a modification of the biaxial
tensile test. This principle allows testing of
materials under multi-axial strain states.
For this purpose a special biaxial draw
bead tool was designed.

Engine design and simulation, combustion technologies, and experimental evaluation
n The focus of the Instiute of Internal Combustion Engines in 2015 was to
connect theoretical and experimental methods of thermodynamic research
on combustion processes. Optical
measurement techniques are a
powerful way of visualizing gas
flow, fuel injection and combustion
inside the cylinder of an engine.
High temperatures and pressures
are challenges for the construction
of optically accessible engines.
A highlight was the completion and first
operation of a new 5 l single cylinder re
search engine with full optical accessibility
through the piston bowl. The engine offers
insight to modern combustion systems for
gas and industrial engines. The results are
used to validate CFD calculations of gas
flow, injection, and combustion in order
to predict the in-cylinder processes. This
helps to save time and costs for future
developments.

Combustion Technologies – CFD Simulation
– Emission Reduction – Injection Technology
CFD calculation of prechamber engine
The reduction of engine emissions and
fuel consumption are drivers for the
improvement of combustion technology.
Engines for gasoline, diesel, and natural
gas are developed and built at the institute
and are available for industrial or public
funded research projects. A key competence for the realization of our engine
concepts is the application of professional
CFD simulation software, which is used
to predict and optimize the gas exchange
phase, in-cylinder swirl, tumble or turbulence, and the phases of fuel injection,
mixture formation, and combustion. Simu-
lation results are used to design improved
geometries of the combustion chamber
or injector nozzles and are then validated
on one of our 13 engine test benches.
Engine out emissions are measured by
means of up-to-date FTIR technology
and a modern particle counting system.
We use component test benches to
evaluate hydraulic behaviour and spray
parameters of fuel injectors. Simulative
and experimental tools allow fast and
effective optimization of both emission
behaviour and engine efficiency. Test runs
on the research engines are planned and
evaluated with statistical methods (design
of experiments, DOE) to reduce time and
costs for the testing procedure.

Injection Systems – Spray Measurement
– Optical Researches
Mie-light measurement
Nozzle flow simulation
In the past decades the injection pressure
of modern diesel engines rose from 1000
bar up to 3000 bar. Our research activities
includes all steps of injection system
development. Key competences are various simulations containing 1-D hydraulic,
3-D multiphase flow as well as spray
simulation. Furthermore, at several test
benches hydraulic and optical measurements of injectors with various fuels could
be carried out. One of the current projects
is focusing on the hydraulic behavior of
orifices in injection systems to validate
simulation results. Part of the project is
the development of a hydraulic test bench
including measurement techniques to
investigate the high dynamic fluid flow
properties in combination with cavitation
and thermal effects. The main target is
to analyse hydraulic elements by using
innovative measurement techniques and
gain information about physical effects to
optimize the design of future injection systems. Furthermore an open-loop control is
under development in collaboration with
the Institute of Applied Mechanics whose
aim is to maintain an optimal injection
rate throughout the entire lifetime of a
common-rail injector subjected to coking,
wear etc. For this purpose, different
injector signals are evaluated in order to
be able to determine the injection rate by
an indirect signal in engine operation.

Natural Gas Engines – Combustion
– Emissions – Simulation
Engine of combined heat and

Utilization of natural gas can be one
step to cope with future energy demand.
Surplus energy from renewable sources
can be stored as hydrogen or methane.
Further development is needed to
fulfill future emission legislation with
high efficiency combustion. Former
research at the institute has dealt with
phenomena modeling of the combustion for different ignition systems, like
open-chamber, scavenged prechamber
or diesel pilot-injection. Further research
projects have the focus on emissions of
unburned hydrocarbons like methane or
formaldehyde. The goal is to understand
the influence of engine parameters like
valve timing, ignition, equivalence ratio
and gas quality. Alternative combustion
processes are another focus to overcome
the trade-off between emissions and efficiency. Stratified or diesel-like combustion
processes are promising techniques and
could allow highest loads without restric-
tions from knocking while keeping lowest
emission levels and highest efficiency with
highly volatile gas qualities. To promote
the development, the research engine
with 5 l displacement has been modified
with an optical access to the combustion
chamber. Combined with CFD-Simulations
a deep insight in the combustion process
is now possible.

Alternative Fuels – Emission Measurement
– Energy Management
Fossil fuels are becoming more and
more scarce and European CO2 saving
policies have been introduced to fight
global warming. Combustion engines can
reduce their output of GHG emissions and
contribute to the transition towards alternative energy by enhancing the efficiency
of energy conversion and by exploiting
CO2 neutral primary energies. Sustainable
biofuels and synthetic fuels can replace
fossil fuels and offer the additional benefit
of clean combustion. A detailed screening
of various oxygen-containing synthetic
fuels was carried out at the institute and
oxymethylene ether (OME1) was found to
burn without particle emissions in a diesel
engine even under unfavourable operating
conditions. Modern methods for the measurement of ultra-low particle emissions
are needed for this and other advanced
engine concepts. Cooperating closely
with the industry, we help to improve such
measurement techniques. Another field of
our research is the utilisation of thermodynamic losses from coolant or exhaust.
The thermodynamic Rankine cycle for
instance allows to harvest enthalpy from
hot exhaust gas and to produce electric
power by means of a steam turbine.

Friction Measurement – Tribology – Engine Mechanics
Reducing piston assembly friction is a
central issue of improving the efficiency
of modern internal combustion engines.
Piston, piston rings, liner and lubricating
oil form a complex tribological system
operating in a field of constantly alternating velocities, pressures, and tempera
tures. Therefore a special research engine
containing a measurement device using
the floating liner method was developed
at the institute. It allows measurement of
the piston assembly friction with a highly
accurate resolution up to 2 N under fired
conditions. That enables the detection
of optimization potential by experimental
analysis. A second research engine was
built up, containing several sensors to
measure crank-angle resolved motions of
the piston and the piston rings. Furthermore the oil film thickness and oil transportation phenomena are measured during
fired engine operation. The measurement
results of both engines establish a deeper
understanding of the behavior and dependencies in the tribological system.

Computational Multiphysics
– Coupled and Multiscale Problems
The interaction of different physical
phenomena plays an essential role in most
engineering applications. The modeling
of such multiphysics problems is one
of our main areas of research. We have
developed robust and efficient modeling
approaches and computational methods
for various coupled problems. Those
problem classes comprise a.o. fluid-structure interaction, electro-chemical, thermo
mechanical, opto-acoustic, coupled
re-active transport, poro-fluid-transport
and thermo-fluid-structure-contact
interaction problems.
Fluid-structure interaction simulation

And also the interplay of effects on
different scales plays an important role in
many scientific and engineering applications. Therefore, there has been increasing
interest in modeling so-called multiscale
phenomena both mathematically and
computationally. We tackle multiscale problems both in CSD and CFD. While in the
first group one focus is on the modeling
of heterogeneous materials, in the second
group the focus is on turbulent flows and
complex fluids.

Computational Solid – Structural and Fluid Dynamics
Vortices (2) in a large eddy
simulation of a boundary layer
Computational structural and solid
dynamics (CSD) is one of the classical
core disciplines within the fast-growing
field of computational mechanics. Our
research activities in computational
structural and solid dynamics cover a
wide range of methods, from nonlinear
solid (hybrid FE meshes, isogeometric
analysis) and structural models (beams,
shells) and corresponding finite element
technology (EAS, ANS, F-Bar) to material
modeling (hyperelasticity, viscoelasticity,
elastoplasticity) at finite strains. Another
focus are complex material phenomena
such as anisotropy, fiber components,
damage, fracture and multiscale modeling
of heterogeneous materials.
Computational contact dynamics represent a particularly challenging class of
structural mechanics problems due to the
non-smooth character of the underlying
laws of physics (e.g. non-penetration)
and the strong nonlinearities introduced

252
by the corresponding geometrical con
straints. In addition, complex interface
phenomena (friction, adhesion, etc.) need
to be taken into account with sophisticated computational models. Here, our
research emphasizes the development of
robust and efficient contact formulations
and discretization methods in the context
of finite deformations and non-matching
meshes/non-conforming interfaces. Lately,
this main focus has been successfully
extended towards contact with wear,
coupled thermo-mechanical contact and
beam-to-beam contact. Furthermore,
strongly coupled fluid-structure interaction (FSI) with contact is another current
research field.
Computational fluid dynamics (CFD) is
the other core discipline in computational
mechanics. We are one of the very few
groups worldwide that do original research
in both CSD and CFD. Our focus in CFD is
on incompressible and weakly compressible flows. We develop novel discreti
zation methods for flow problems as well
as novel approaches for turbulent flows
based on large eddy simulation (LES) and
detached eddy simulation (DES). Another
focus is on multiphase flows and flows
coupled to other fields like in fluid-structure interaction, electro-chemistry or
reactive transport problems.

Computational Bioengineering and Biophysics
Our research in the biomedical engineer
ing area includes a variety of different
fields. In all of them we collaborate with
experts from medicine, biology or biophysics. Some activities are the development
of a comprehensive coupled multiscale
model of the respiratory system, of
a model for rupture risk prediction of
abdominal aortic aneurysms, comprehensive cardiac modeling, simulation of
surgical procedures or cellular modeling.
In recent years we have also successfully
entered the area of biophysics, where we

could develop a novel, theoretically sound
and highly efficient approach for the
Brownian dynamics of polymers. Based
on this unique approach we meanwhile
could study and answer a number of open
questions in the biophysics community.
Vascular Growth and Remodeling in Aneurysms
(Emmy-Noether Group headed by Dr. C. Cyron)
Aneurysms are focal dilatations of blood
vessels that often grow over years and
finally rupture. Rupturing aneurysms are
among the leading causes of mortality
and morbidity in industrialized countries.
While over the last decades our general
understanding of the biomechanics of
aneurysms has advanced substantially,
the factors governing their growth –
although key to develop future therapies
– remain poorly understood. In February
2015, Dr. Christian Cyron established the
Emmy-Noether group for vascular growth
and remodeling in aneurysms at the
Institute for Computational Mechanics. It
aims at exploring the biomechanical and
biochemical mechanisms governing the
growth of aneurysms, with the perspective
of exploiting these for the development
of future therapies and computer-aided
diagnosis. To this end, the Emmy-Noether
group will combine advanced methods
from computational mechanics with stateof-the-art medical imaging technology
and machine learning. The Emmy-Noether
program of the German Research Foundation (DFG) was established in 1999 to
support groundbreaking projects of young
researchers. Since then the DFG has been
supporting only eight Emmy-Noether
groups in the area of mechanics and
mechanical design.

The complexity and scientific broadness
of the majority of our research projects
make highest demands on both the
‘modus operandi’ and on the research
environment itself. This is why LNM
with its entire scientific staff develops
and maintains the parallel multiphysics
research code BACI (Bavarian Advanced
Computational Initiative) which is probably
unique even from a global perspective.
BACI is mainly based on finite element
methods FEM, but also features other
discretization techniques such as HDG,
particle and meshfree methods. All past
and present activities at LNM have been
– and all future projects will be – realized
within this HPC platform.

Real-time tele-robotics in space – space technologies – exploration & human spaceflight –
nano satellites – spaceflight systems engineering – hypervelocity-lab
n In 2014-15, like the years before, the Institute of Astronautics focused on
the development of satellite and space exploration technologies.
In particular:
n Real-time teleoperation for on-orbit
servicing
n Novel inter-satellite link communication
systems and architectures
n Exploration technologies, incl. lunar
dust processing and mitigation, and
analysis of life support systems of
habitats and space suits
n Spacecraft technologies and CubeSat
educational satellite program
n High velocity impact physics and
micrometeoroid and space debris
simulation and assessment
On-orbit servicing is a growing field of
space activities, where satellites or other
spacecraft in space are serviced (such
as refueling, maintenance, or upgrade) or
deorbited by a servicing satellite if defunct.
This service can be accomplished by an
operator on ground teleoperating a robot,
cameras, or else on the servicing satellite in
real-time. As a highlight in 2015, the large
simulation environment called RACOON
Lab, with the dimensions 6 m x 10 m x 5 m
went into utilization. In this laboratory the
proximity operations of the two satellites
can be simulated, while the operator is
located in the institute’s mission control
center or anywhere on earth. Realistic
tele-operation is performed by real-time
satellite links via a ground station on top
of the the institute’s building and a relay
satellite in geostationary orbit.
For the renewed interest of NASA and ESA
in human space exploration, an adapted
and highly reliable life support system (LSS)
is mandatory. In 2015 the Institute of Astronautics has improved the modeling tool
V-HAB for arbitrary LSS, and deployed it in
NASA and MIT projects. The modeling not
only includes the life support components,
but in particular a high-fidelity human
model for astronauts living and working in
this LSS.
In January 2015, LRT also started the
development of TU Munich’s second
pico-satellite MOVE II.

Satellite Technologies –
MOVE-II CubeSat Educational Program
The CubeSat program MOVE (Munich
Orbital Verification Experiment) was
initiated in 2006 at LRT. The primary
objective of the program, as in many
university-led CubeSat programs worldwide, is the hands-on education of
students. A secondary objective was
to create a platform for validating new
technologies in space. The first CubeSat
of the program, called First-MOVE, was
launched on November 21, 2013. The
programs’ second CubeSat, MOVE-II, is
currently under development, with launch
currently expected in late 2017. About
30 undergraduate and graduate students
are currently working on the satellite,
with one staff member of LRT as full-time
project manager. MOVE-II is a cooperation between the LRT and the student
LISAMS+ high-gain antenna during antenna pattern tests at the Hochschule München –
compensated compact antenna range facility
257
group Wissenschaftliche Arbeitsgemeinschaft für Raketentechnik und Raumfahrt
(WARR).
Project Details
MOVE-II will evolve the subsystems that
were developed in-house during the FirstMOVE program. With more demanding
on-board data processing and storage
needs for planned scientific payloads, the
evolved on-board data handling system
(OBDH) will be based on a commercial
off-the-shelf, multicore central processing unit. Combined with a robust mass
storage system and a failure tolerant file
system, the OBDH targets increased per
formance needed on CubeSat missions
as well as robustness against induced
errors and thus improving data integrity.
Furthermore, an advanced solar panel
deployment mechanism is currently under
development based on the experience
from First-MOVE. The use of shape
memory alloy technology will enable
repeated deployment tests with the flight
units, something that was not possible
with the previous, disposable design. The
mechanism was successfully verified on a
sounding rocket launch campaign in early
2015. The overall goal of MOVE-II is to
test and verify the so-called satellite bus,
meaning all parts of the satellite required
to run a payload. On MOVE-II, this
includes communications, on-board data
handling, the attitude control system, the
power supply system, the structure and
the thermal control system.

On-orbit servicing and space debris
removal missions with tele-operation, a
key research area of LRT, require transmission of multi-channel video signals and
spacecraft sensor and control information
which can exceed data rates of 20 Mbps.
These communication scenarios require,
among other technologies, high-gain
antenna systems and novel communication architectures supporting real-time
operations. Projects in this research area
include the development of novel direct
radiating array antenna systems (LISA),
a new project in hybrid manufacturing
technologies for waveguides using galvanic processes in conjunction with lost
core 3D printing technologies (CFRM-HF)
and the new project CopKa, targeting the

Project Details
The Light-weight Intersatellite (Link)
Satellite Antenna (LISA) R&D projects
(TUM-LRT and LLB) develop and demonstrate novel manufacturing technologies
for Ka-band communication hardware
and use novel copper-galvanically
manufactured horn antennas with a
low-loss waveguide distribution network.
Copper-galvanic allows the design of high
performance, low loss and high frequency
waveguide structures, using a lost core
galvanic manufacturing process. As a
technology demonstrator, two types of
high gain Ka-band antennas were built
as 40 x 40 cm reference models. A fast
precision 2-axes mechanical steering
mechanism is required to accurately
point these high-gain pencil antennas,
together with a novel two-channel, lowloss Ka-band waveguide rotary joint with
research partners from industry and the
University of Applied Sciences Munich. As
an alternative to mechanical steering, an
option for a mechanism-free electric steering solution was developed with partners
from industry and the Technical University
Darmstadt. Using liquid-crystal phase shifters in the waveguide distribution network
of the direct radiating antenna array uses
superposition of phase-shifted signals
from each horn in the array to provide an
apparent beam steering.
CopKa is a new project partnership (201518) between TUM-LRT and the IMST
GmbH company in Kamp-Lintfort, and it
targets the technology development and
demonstration of a multi-sensor-based
emergency services mission using a UAV
helicopter and Ka-band satellite links.
The project will develop and test novel
communication architectures as well as
supporting antenna control and manufac-
turing technologies, and demonstrate the
integrated system in various test scenarios
in cooperation with the TUM firefighting
services.
CFRM-HF (carbon fibre reinforced metals
for HF structures) also is a new project for
TUM-LRT and LLB (2015-17), investigating innovative manufacturing methods
for microwave components in aerospace
applications-technology evaluations and
demonstrations using hybrid materials and
manufacturing technologies for microwave
feed systems.

RACOON – Real-time On-Orbit Teleoperation
The RACOON Lab features a satellite
proximity operations simulation environment. The lab consists of a hardwarein-the-loop simulator that represents
position and attitude of two spacecraft in
close proximity (e.g. for rendezvous and
docking maneuvers). The lab provides
realistic lighting conditions and hardware
sensors to simulate realistic sensor data
for the development of new spacecraft
technologies (e.g. control algorithms). The
real-time capabilities allow the inclusion of
a human operator into the control loop for
research in the area of human spacecraft
interaction. This includes user studies for
optimal human machine interface design
or operator workload evaluation.

Exploration Projects
LUISE-2
The scope of project LUISE-2 (Lunar
In-Situ Resource Experiments) is to
determine the thermal and mechanical
properties of lunar regolith that are impor
tant for the transport of lunar samples
and the thermal extraction of volatile
content. LUISE-2 is funded by the German
Aerospace Agency (DLR) with LRT being
the prime contractor since 2012. Within
this project alternative methods for volatile
extraction are investigated under lunar
environmental conditions, which are also
interesting for future in-situ resource
utilization (ISRU) applications. LUISE-2
investigates lunar regolith handling and
analysis processes such as sampling,
preparation (transport, measuring, filling),
thermal gas evolution, and gas analysis.
For the relevant gas extraction processes
the thermal properties of lunar regolith
simulant were determined experimentally.
New concepts for heaters and instruments
that can be used in a lunar application,
more specifically on a mobile lunar
surface craft, have been developed and
tested. Test beds for the ‘stamp heater’
instrument concept were established
to evaluate the heat transfer into lunar
regolith simulant with a single electrically
powered heating rod. This concept was
further refined and supporting studies
for the design of a demonstrator were
conducted. Additionally the research in
LUISE-2 focused on the gas permeability
of lunar regolith to evaluate the process of
volatile transport through a sample.
The outcome of project LUISE-2 contributes to a better understanding of sampling
and thermal extraction processes on the
moon and provides useful data for the
conception of a scientific in-situ sampling
and analysis instrument. Furthermore
the results are relevant for broader ISRU
applications on the moon.

PROSPECT
The instrument package PROSPECT
that is developed under contract to the
European Space Agency (ESA) for the
upcoming Luna-27 mission to the lunar
South Pole makes use of the ProsPA
(Lunar Polar Prospecting – Processing
and Analysis) gas analysis instrument.
LRT was involved in the Phase A study
of this instrument and responsible for the
development of sample ovens that contain
the lunar regolith samples for thermal gas
extraction and subsequent gas analysis.
Trade studies supported by computer
simulations and thermal-vacuum testing
of oven specimen were performed to
evaluate the problem of heat transfer into
the samples, temperature distribution
within the sample, and to assess the
feasibility of the required heating modes.
Robotic Exploration in Extreme
Environments – Helmholtz-Project
Robex
The LRT participates in the Helmholtz
financed project Robotic Exploration
in Extreme Environments (ROBEX).
ROBEX covers topics of robotic deep
sea exploration as well as robotic space
exploration where both research fields
benefit from synergies. LRT research
within ROBEX focuses on two topics: on
one hand the effect of accelerated lunar
dust particles on standard space materials
is investigated and on the other hand LRT
studies various thermal aspects on robotic
planetary operation.
V-HAB – Modeling and Simulation of
Life Support Systems
To fully assess the long-term operation
and stability of life support systems (LSS)
for exploration missions, static analysis
methods are insufficient. Establishing
mass balances and selecting technologies
based on average performance values is
a fast and proven method for feasibility
studies but, once the system design
becomes more detailed, certain aspects of
the system behavior cannot be captured.
To provide this additional information, the
Institute of Astronautics has developed
the Virtual Habitat or V-HAB. V-HAB is
a MATLAB®-based simulation software
which enables the dynamic simulation
of life support systems, the humans
occupying the simulated habitat and the
mission that is being performed. The first
development step was completed in early
2013 when the simulation system was
validated by comparing data from a virtual
model of the International Space Station
LSS with actual flight data. This coincided
with the completion of a dissertation on
the rationale and development of V-HAB
by Dr. Markus Czupalla. Four other
dissertations where derived from this initial
work, each adding to V-HAB’s already
broad spectrum of capabilities. One of
these dissertations was completed in late
2013 by Dr. Phillip Hager who contributed
a dynamic thermal simulation tool to
capture the thermal dynamics of moving
objects (e.g. astronauts, rovers) on the
lunar surface. The three other disserta-
tions, which are still in progress, cover
the simulation of portable life support
systems for space suits, the addition
of dynamic crew scheduling algorithms
to the human model and dynamic,
thermal path optimization for rovers
and astronauts on planetary surfaces.
In addition to the previously mentioned
dissertations, the group published its work
at the annual International Conference
on Environmental Systems (ICES), the
preeminent conference for the life support
system community. The peer-reviewed
papers were well received and the already
strong ties to LSS experts from NASA and
industry could be expanded. In total the
group published three papers at the ICES
2015 conference. In addition to these
conference papers, the group also published three journal papers and continued
the extensive involvement of students in
the current research, producing a total of
14 Bachelor’s theses, 6 Master’s theses
and 5 term papers in 2015.

Experimental and theoretical characterization of metallic materials
n The focus of the Institute of Materials Science and Mechanics of Materials
(WKM) in 2015 was to develop further the field of processing microstructure
properties relationships of load bearing materials concentrating on metallic
materials such as high strength steels, titanium, nickel, aluminum and
tungsten alloys. Research is performed employing theoretical, numerical
and experimental techniques with equal importance. The associated State
Material Testing Laboratory serves as an important interface to industry with
respect to research oriented (offroutine) testing of materials.
Research activities concentrate on plasticity and failure of high strength dual-phase
steels, strain localization of multiaxially
deformed high strength steel sheets and
residual stress analysis and quantification
of the time dependence of residual stress
states via experimental and theoretical
approaches.
Significant advances were made in the
modeling of microstructure evolution
of the titanium alloy Ti-6Al-4V during
selective laser melting, the integration of
precipitation hardening into the process of
densification of cast aluminum alloys by
hot isostatic pressing and the solution of
several inverse problems associated with
the design of working cathodes as used in
electrochemical machining.
Work has begun on several new topics
such as accumulative roll bonding of steel
sheets or high entropy high temperature

the successful completion of the habilitation of Dr. C. Krempaszky for mechanics

Plasticity and Failure of High-Strength Sheet Materials
for Automotive Applications
The desire to produce steel sheet material
with high strength, excellent formability
and a rather low content of alloying
elements has led to the development of a
multitude of microstructure-strengthened
steels. Among these are the ferriticmartensitic dual-phase (DP) steel grades,
which are produced in a multi-step heat
treatment. Their microstructure consists
of a matrix of ferrite (soft), reinforced with
isolated particles of martensite (hard).
Research activities at WKM related to
DP steels focus on heat treatmentinduced microstructural stresses and
strains, their unusual plastic deformation behavior, and their microstructure
governed failure behavior.
Phase averaged von Mises stresses in two different microstructures (bottom left and right)
as a function of macroscopic strain in tension and compression. The martensite of the left
microstructure exhibits an ‘unloading’ from heat treatment-induced stresses (i.e. the initial stress
in the graph) up to roughly 0.5% of macroscopic strain. This effect causes higher macroscopic
flow stress in compression than in tension. (Source: WKM)
265
For a systematic study of the influence of
microstructure features on plastic flow and
failure of DP steels, a simulation model
based on micro-continuum mechanics
and tessellated microstructures was
developed at WKM. Systematic simulations conducted with computer generated
microstructures subjected to the same
heat treatment and subsequent deformation routes as real DP steels served to
explain several phenomena typical to this
steel class.
For the first time it became possible
to clearify the importance of heat treatment-induced micro-strains for the
initial plastic flow behavior and that of
heat treatment-induced local deviatoric
stresses for the experimentally observed
load type-dependent macroscopic flow
stress (see figure).
The macroscopic strain for microstructural
failure initiation in DP steels can be correlated with their microstructural heteroge-
neity. The higher the heterogeneity caused
by a high contrast of phase strength or a
large martensite phase fraction, the lower
is the macroscopic strain for local failure
initiation.
Investigations are also conducted on
the process of accumulated roll bonding
(ARB) of dual-phase steels to evaluate the
feasibility of this special production route
for high strength steels. ARB currently is
only applied to low strength steel grades
and soft aluminum alloys, there revealing
its potential to increase strength markedly
by grain refinement induced be severe
plastic deformation.

Strain Localization Analysis of Multiaxially
Deformed High Strength Sheet Steel
Strain localization is limiting the formability of sheets and occurs on different
length-scales. Particularly in case of
multiphase materials exhibiting a high
contrast in phase-specific strength, it
appears necessary to take into account
the microscale.
In the course of the research activities at
WKM, the forming limits of dual-phase
steels are investigated using a decoupled
sequential multi-scale modeling approach.
This approach adopts a shear band
analysis employing the concept of the
acoustic tensor and combines a mechanical analysis of unit cells representing the
microstructure on the grain level and the
evolution of macroscopic mechanical field
quantities in Nakajima test specimens.
It could be shown that the morphology of
the microstructure influences the position
and orientation of the global shear band
within the microstructure while the phase
strength contrast triggers shear band
formation.

Residual Stress Relaxation and Residual Stress Analysis
Experimental method for monitoring the evolution of
thin-walled bent profile distortions. (Photo: WKM)
The redistribution of macroscopic residual stresses may lead to component
distortions, which, in the worst case, do
not conform to the required dimensional
accuracy of the component. Residual
stress redistribution may result either from
the removal of portions of the workpiece
during machining or from stress relaxation
of the material due to microscopic diffusion processes. For metallic materials, the
latter play a substantial role only in case of
elevated temperatures. However, in case
of very thin/slender components, even
slight stress redistributions due to stress
relaxation at ambient temperature can
result in undesirable distortions increasing
with time.
In this context, research activities focus on
the investigation of stress redistributions
in thin-walled bent profiles and the identification of the underlying microscopic
mechanisms. This includes the development and application of experimental
methods for residual stress analysis and
for monitoring the evolution of component
distortions as well as the theoretical
estimation of the evolution of the residual
stress state using adequate semianalytical
and numerical modeling approaches.

Microstructure Evolution of Ti-6Al-4V
During Selective Laser Melting
Selective Laser Melting (SLM) is an
additive manufacturing process used
to produce near net shape parts with
complex geometries from 3D CAD data
directly, thus being economical for small
batch series and individual items. In SLM,
components are produced layerwise from
metal powder, which is locally fully melted
by a laser and then solidifies by self-quenching, free convection of shielding gas
and thermal radiation from the free surface. This thermomechanical treatment of
the material results in microstructures that
differ significantly from those processed
conventionally by forging or casting.
WKM puts much effort into the development of multiphysics process models
aiming at the prediction of SLM-generated
microstructures. Main ingredients of these
models are – besides heat input and heat
extraction modules – the consideration
of kinetic aspects of liquid-solid and
solid-solid phase transformations which
control the evolution of microstructures.
Detailed microstructure investigations

alloy Ti-6Al-4V which after solidification
undergoes a solid-solid transformation
from the high-temperature -phase
to the ’-phase upon cooling to room
temperature. Since there exists a distinct
orientation relationship between these
two phases, the crystallographic features
of the -phase can be reconstructed
from crystallographic data collected for
the ’-phase. It could be shown that the
-phase solidifies as elongated grains
oriented parallel to the build-direction of
the part exhibiting a fibre texture.
Based on these findings a simulation
tool was developed at WKM capturing
interfacial motion, grain orientation and
driving forces responsible for microstructure evolution.

Electrochemical Machining
Electrochemical machining of a

a torus shaped cathode (not

the current density on the workpiece surface (left); experimental

Anodic metal dissolution at high current
densities (such as in electrochemical
machining (ECM) and/or precise electrochemical machining (PECM)) is increasingly used when conventional machining
reaches its economical and/or procedural
limits, as e.g. for temperature sensitive,
brittle or high strength metallic materials.
In ECM the workpiece represents the
anode of an electrolytic cell, whereas the
tool is defined by the opposing cathodic-
ally polarised electrode of a specific
geometrical shape. To ensure that the
desired workpiece geometry evolves
in a controlled machining process, the
pre-determination of the necessary
shape of the cathode is imperative. This
determination poses a major challenge in
ECM.
Therefore a procedure – based on the
C++ library OpenFOAM – was developed
at WKM to calculate cathode shapes for
the manufacturing of complex 2- and
3-dimensional workpiece surfaces. Due
to its improved accuracy compared to
existing shape-calculating methods, this
approach reduces the number of expensive iterations in tool manufacturing. In
addition, insights from simulation results
(both the simulation of the dissolution
process and the solution of the inverse
problem to identify desired cathode
shapes) are now used to identify processand material-related effects that can be
evaluated separately in an experimental
test setup.
Current experimental research efforts are
directed towards the influence of variations in mechanical material properties
– such as residual stresses and dislocation densities, both of which can result
from forming or heat treatment – on the
macroscopic dissolution rate of selected
materials.

Failure in Integrated Circuits
Growing demands on performance and
durability of integrated circuits require
an understanding of possible failure
mechanisms like crack initiation within
the interlayer dielectric and surface
roughening of the metallization plate. One
of the main causes for such failure arises
268
from the mismatch in thermal expansion
between the materials involved (conductor
paths are made of aluminum and the
surrounding interlayer dielectric of silicon
oxide) leading to thermo-mechanical
loads and, consequently, to various
types of damage. Throughout their life,
electronic components undergo millions of
thermo-mechanical load cycles, so that an
experimental life cycle analysis during the
development process is costly and may
not be feasible at all.
Via simulation the influence of the aluminum microstructure on typical failure
mechanisms was investigated utilizing a
crystal plasticity material model taking
into account the microstructure, the grain
orientation, the grain size and the temperature dependency of relevant material
properties. A number of experimental
observations could be confirmed by these
calculations like the stabilizing effect of
a passivation layer on the surface roughening and the significant life extension by
reducing the grain size of the conductor
path grains. Grain size and orientation
both influence the magnitude of surface
roughening (see figure). Compared to
grain size the influence of grain orientation

seems to play a less important role. Parameter studies are currently undertaken in
order to find an optimum microstructure
for aluminum leading to a minimum failure
probability.
Failure in Tungsten under High Heat Flux Loads
Currently the International Thermonuclear
Experimental Reactor (ITER) is being
built at Cadarache, France. Engineers are
facing challenging material selection problems especially when designing components which are in contact with the fusion
plasma to extract thermal power from the
plasma. Power densities of more the 10
MW/m² are predicted to be withstood by
these materials. The thermo-cyclic loads
imposed on plasma facing materials
(PFMs) e.g. in the divertor of a fusion
reactor show great similarities to the
loadings of accelerator targets and X-ray
anodes. For all these applications tungsten or tungsten alloys are the preferred
materials to withstand short-duration high
heat-flux loadings. While tungsten exhibits
favorable short-term high temperature
properties, it is brittle at temperatures
below the ductile to brittle-transition and
shows undesired grain growth during
long-term exposure. In collaboration with
Siemens AG and the Max-Planck-Institute
for Plasma Physics, WKM successfully
studied fracture behavior and microstructure evolution of relevant tungsten grades
both experimentally and via micromechanical modeling. Finally, a new processing
route was developed for the production of
isotropic and fine grained tungsten grades
via tape casting.

Biocatalysis
High demands are set upon the optical
purity of building-blocks for the production of pharmaceuticals. Due to the
high natural selectivity of biocatalysts,
biocatalysis appears as favorable method
for the purpose of chiral syntheses. Major
research interests are the development of
new reaction engineering methods and
devices to intensify whole cell biotransformations of hydrophobic, unstable and/or
toxic substrates up to the technical scale.

Production of enzymes with combined
immobilization in one process step
reduces the costs for biocatalyst preparation. Therefore, enzymes were first
anchored to the inner membrane of E.
coli. The cells were subsequently opened
by expression of a lytic phage protein to
obtain cellular envelopes with membrane
anchored enzymes.

Fermentation
Making use of microorganisms for the
production of chemicals from renewable
resources is the core of industrial biotechnology. Reaction engineering analyses of
metabolically optimized producer strains
and metabolic analyses of microorganisms
in production processes are necessary for
efficient bio-production on an industrial
scale.

Gas Fermentation
Special microorganisms are able to
produce chemicals with carbon dioxide
as sole carbon source. Energy may be
supplied from sunlight or hydrogen gas.
Bioprocess engineering is the key to
make use of these energy sources for the
microbial production of chemicals from
carbon dioxide on an industrial scale.

Bioprocess Integration
In many cases, downstream processing
is by far the most cost-intensive step
of a bioprocess. Often, multiple-step
bioseparations are required yielding rather
low product yields. Therefore, existing bioseparation processes should be improved
and combined to reduce the number of
process steps. The focus is on bioprocess
integration of fermentation/biocatalysis
and downstream processing.

Medical and polymer engineering, process & manufacturing method development,
sterile production, vascular and cardiac engineering
n The Institute of Medical and Polymer Technology inaugurated the
Central Institute for Medical Engineering in 2000 and established in the
same year the Masters Curriculum of Medical Engineering, the first one
of its kind on university level in Germany, and it offers a comprehensive
curriculum in medical engineering and in polymer engineering. Today
more than 400 students follow the institute’s courses and seminars every
semester. Teaching is focused primarily on industrial and clinical needs.
The Institute represents two main and
interacting focus areas:
A)Medical engineering with a strong
impact on biocompatible materials
engineering, mainly process engineer
ing of materials and designing of tools,
molds and parts, specified for medical
implants made from non-metallic organic
materials. It develops new surfaces and
structures of material-cell-interfaces,
i.e. porosities, in order to optimize
biocompatibility behaviour following
implantation in patients. It provides
respective testing, including biotoxicity
testing and the development of tissue
engineering systems.
B)Polymer engineering and tooling is intensively represented with an outstanding polymer technology infrastructure.
All industrially relevant processes are
presented in teaching, micro-injection
molding is a key research area. This
includes the entire designing and
manufacturing process of tools,
devices and machines, i.e. the most
compact injection molding machine
worldwide has been designed and
manufactured by us.

stability and their wide range of mechanical properties. The objective of the
project is to verify the suitability of medical
grade silicones as long-term implantation
material with in-vitro tests. The biological
properties of the silicone surface are
optimized with specific material modifications improving blood compatibility and
interactions with subcutaneous tissue.
Those modified silicone elastomers are

medical applications are small in dimensions with a reduced adhesion interface.
In this research work the adhesion of
different elastomers (thermoplastic elastomers and self-adhesive silicone rubber) on
thermoplastic substrates is investigated
using miniaturized test geometries. The
mechanical bond strength is evaluated
via peel tests and surface modifications
are applied to increase adhesion.
Moreover, the stability of the composites
against fluids in a medical environment
or sterilization processes is studied. This
investigation builds a profound basis
for a selection of suitable polymers for
hard-soft composites in different medical
applications.

Perspectives for production
n In 2015, the focus of the Chair for Machine Tools and Production
Engineering was on the machining of materials and the processing thereof
into composite materials. With emphasis being placed on lightweight
design, new production processes were researched and further optimized
using suitable simulation models.
With regard to light-weight structures that
are optimally adapted to the respective
loads, bionic approaches such as the
adaptation of natural honeycomb and grid
structures have proven to be particularly
suitable for achieving the desired goals in
the area of additive production processes.
With the objective to use the suitable
material in any location, the research
is focusing in the area of joining and
separating technology on producing joints
of different metals or metal to plastics that
so far could not be produced. Thermal
simulations for joining processes have
proven their particular potential, which
allow innovative production processes
with respect to the production of lithium
ion cells.
For the last 21 years, the Application
Center Augsburg has transferred the new
production technologies to industrial
production, from which mainly small and
medium-sized companies in the BavarianSwabian region benefit.

Machine Tools
In the context of the Machine Tools
working group, we analyze and optimize
cutting production systems. The studies
focus on the examination of the dynamic
machine behavior, the cutting process
and the influencing thermal factors.
Thanks to the consideration of aspects
of instrumentation and control, the
study horizon is expanded beyond
purely mechanical structures to complex
mechatronic systems. Modern simulation
methods, such as the finite elements and
multiple-body simulation, are used for
these examinations in order to reflect the
machine features in detail. By coupling
these with developed cutting-force
models, interactions between structure
and process can be demonstrated.
Furthermore, energy-related aspects
which interact with the machine properties
are in the focus of the investigations.
The energy efficiency of machine tools is
becoming more and more a competitive
factor.

The iwb Application Center Augsburg (AzA)
is the technology transfer center of the
Institute for Machine Tools and Industrial
Management at the Technical University
Munich. As part of this activity, the AzA
supports particularly the medium-sized
industry in Bavaria with the know-how of
the university in the area of production
engineering in the long term. The following
four research fields are offered at the iwb
Application Center Augsburg together with
the scientists in Garching:
Projects

Joining and Cutting Technology
On its way from a semi-finished to a
finished product, technical products
generally go through several joining and
separating steps that are particularly
relevant for the high quality and economic success of the production. The group
Joining and Cutting Technology deals
with this focal point and is working on
innovative production processes. The aim
282
of the research and development activities is the optimization of quality- and
productivity-optimized and scientifically
sound production processes. To this
end, machinery with modern laser beam
sources, friction welding equipment and
a wide range of measuring and analysis
instruments is at the disposal of the
group. The competences of the working
range from process analysis, system
technology, and technology consulting to
simulation.
