燃料电池轿车碰撞结构安全设计的研究

摘要

探讨某款燃料电池轿车碰撞结构安全设计的思路,阐述其具体设计,并借助有限元法对该车模型进行了碰撞模拟,根据模拟结果进行了改进设计,并验证改进设计的有效性.结果表明改进后的碰撞结构安全设计可行、有效.%The thinking of safety design for the crash structure of a fuel cell car is investigated with its design details expounded, and a crash simulation is conducted on the model for fuel cell car using finite element method. According to the results of simulation, the design is modified with its effectiveness validated. The results show that the modified safety design of crash structure is feasible and effective.
