汽车侧面碰撞B柱结构优化设计

The optimizational design of the vehicle B pillar in the lateral impacte

某轿车侧碰仿真试验过程中,发现B柱上端侵入量过大,针对B柱结构进行问题分析,提出结构优化方案。经仿真验证,优化后的结构满足碰撞要求和成型要求。

In the simulation test of the lateral impacte, the invasive displacement of the top of the B pillar is too long. So the structure of the B pillar should be analysised and a optimizational method should be supplied. After the simulation test, the optimizational structure can meet the requirements of lateral impact and forming
