Integrated Simplified Crash Modelling Approach Dedicated to Pre-Design Stage: Evaluation on a Front Car Part

Acess to a simplified methodology for simulation and crash optimization is needed by transportation field manufacturers during the pre-design stage for a structure's global behavior to be quickly ascertained. Multibody dynamics can be used due to large plastic deformations that the shock localizes. Non-linear spring elements represent these dynamics through axial compression and pure bending analytical model collapse responses. These non-linear spring numbers and localizations, however, directly influence the quality of results, modeling times, and the central processing unit. An automatic collapse mechanism non-linear response and localization method, based on simultaneous global beam finite element model and analytical results use, is proposed and implemented into an FE code PAM-CRASH beta version. The robustness of this new tool is evaluated by studying a commercial front car part under frontal crash conditions.
