With "Conceptual Structure Optimization for Crashworthiness" develop crash efficient vehicle structures, through evaluation and optimization of load paths and sections in the concept phase

What is it?

The core disciplines for structural performance are crashworthiness, NVH (noise, vibration and harshness) and durability. The architecture design in the concept phase is the most effective solution for optimal crashworthiness performance. However, the crashworthiness simulation takes a significantly longer time than the other two. Companies need a workflow that provides flexible modeling and faster performance, which are essential to support the frequently changing concept designs.

What is the value

Crashworthiness to be considered during the concept design phase
Faster product development
Optimization for higher performance at a lower cost

Why is this important?

To improve performance and safety of automobiles, automakers have studied vehicle body structures and crashworthiness over many decades. In fact, automakers have a vast database of test and analytical data that needs to be connected and considered in their development process. However, often that data is not able to be used for sensitivity studies or DOE related to crash analysis due to long computing time required for crash simulations

How do we deliver value?

Concept Structure Engineering embraces the best of both CATIA and SIMULIA for integrated modeling & simulation during concept design.

CATIA/SFE facilitates parametric conceptual design exploration maintaining all needed modeling, interconnection, and simulation attributes
SIMULIA technologies facilitate faster, iterative multi-disciplinary optimization including Safety, N&V, and Stiffness/Strength trade-off studies

With our experts @AI for CATIA and @YC for SIMULIA,
we have developed a set of assets to
