| Abstract: | Aiming at the problem of vehicle side crash, the full vehicle finite element model was established by software Altair Hy- perMesh, and the simulation that rigid wall was crashed into vehicle was analyzed by LS-DYNA. The energy curve and other related data in crash course were gotten. In order to strengthen vehicle＇ s crashworthiness, the structure and material of the front seat beam were optimized. So the requirements of side crash safe design are met. |
