Advanced Body in White Architecture Optimization

During the BIW concept developing phase, some key design variables, such as rails and pillars width and position, shell thickness, etc, and multi-attribute responses from safety, NVH, and durability are considered to explore the design space. Isight DOE design drive is used to assess the impact of the variables on the objectives, and this helps the engineer to better understand the design space and give design recommendation. Approximations component is used sequentially to create fast-running surrogate models to replace the real CAE simulations. Finally, the Optimization tool is used to perform a trade-off study, and this helps engineer to know what is the minimum cost for the design to meet all design targets, or when the BIW weight is fixed, what is the potential maximum design performance.
