摘　　要：搭建了整车与行人头部撞击有限元模型,并选择了碰撞试验点。应用Hyper Mesh软件更改原车发动机舱盖的夹层材料为泡沫铝,应用LS-DYNA软件模拟更改材料之后的发动机舱盖与行人头部碰撞的过程,对比分析了更改材料前后各试验点的加速度曲线及头部损伤值HIC的变化情况。Built vehicle and pedestrian head impact finite element model, and select the crash test points. Hyper Meshapplication software changes the original car bonnet of aluminum foam sandwich material, the application of LS-DYNAsimulation software engine hatch with a pedestrian head impact of process changes material after the comparative analysis ofthe acceleration curve before and after each test material change and points head injury changes the value of HIC.
