Multidisciplinary optimization (MDO) of a vehicle body structure for the three major performance attributes - NVH, Durability, and Crashworthiness - has been hindered by long crashworthiness simulation times. The Radial Basis Function (RBF) methodology along with an abstracted model can reduce lead time at the concept stage of optimizing crashworthiness of a vehicle body structure.
Download this guide to learn about:
- The lumped-mass spring model, a highly abstracted model that can be applied in early stages of concept design
- Why the lumped-mass spring model has not been widely used due to the detailed shape of individual components
- The trial and error method, including modifications to the design of components that are tested with physical tests or FE simulations, that the lumped mass spring model relies on
- How the RBF methodology, a parametric optimization method, uses approximation models to find the proper section for all components and reduces overall lead time at the concept stage
