Abstract:

Based on the mechanism of side pole impact, the influences of energy transmission and crashworthiness among minivan and sedan's center of gravity, structure and packaging was compared and analyzed herein. The improvement direction of minivan structure was put forward by the analyses. The simulation of minivan side pole impact and structural optimization was carried out. The results show that crashworthiness performance of minivan is improved significantly, which proves that the optimization methods of minivan side pole impact are feasible.

Key words: minivan, pole side impact, simulation analysis, structure optimization
