Goals of VPD
• Use advanced tools and methodologies (modeling and simulation) in
order to have a complete representation of the new product (geometry
and functions) in order to:
• reduce decisional risks
• minimize time and costs
• reduce the number of physical prototypes
• Increase quality
The approach is
• Complete digital representation of the Poduct (Digital Mock-Up)
and the Plant (Virtual Manufacturing)
• From Field to bench (mission identification and testing)
• From the bench to the math (mission simulation)

Topology Optimization
• Optimized structural configuration based on specified loads.
• Applied in the early stages of product development
The combine rear frame was designed using topology optimization.
The loading capacity was increased by 40% without cost increase.

Conclusions
•
Virtual Product Development allows effective and quick “Design
Reviews”, including partners and suppliers also from remote
locations.
•
The communication process among all the actors involved in the
product development process becomes more effective
•
The product quality and project robustness are improved,
minimizing costs at the same time
Thank You!
