摘要
针对某一由普通轿车改装的氢燃料电池轿车,利用非线性有限元分析软件LS-DYNA,对其正面、侧面及后面碰撞进行仿真,分析了该燃料电池轿车相对于其原型车在碰撞安全性方面的变化,以及其部分高危零部件在碰撞中的表现,并做了相应的改进设计。最后总结出改装型燃料电池汽车在不同的工况下相对其原型车的碰撞安全性的变化趋势,为燃料电池轿车碰撞安全性设计以及相关法规的制定提供了依据。
Simulations on the frontal, side and rear crash of a hydrogen fuel cell car （HFCC） converted from an ordinary car are conducted, using nonlinear finite element analysis software LS-DYNA. The changes in crashworthiness of HFCC relative to original car and the behavior of its high-risk components during crash are analyzed, with relevant modification design done. Finally the change tendency in crashworthiness of HFCC relative to original car at different working conditions is summarized, providing a basis for crashworthiness design of HFCC and the formulation of relevant regulations.
