摘　　要：为了提高汽车的节能性、安全性,文章以某汽车发动机罩板为设计原型,以轻量化和刚度满足要求为约束条件,设计了泡沫铝层合结构汽车发动机罩板;利用有限元仿真分析方法对2种结构汽车发动机罩板的静态性能及其与行人头部碰撞保护性进行了分析。结果表明,泡沫铝层合结构汽车发动机罩板不仅可以实现汽车轻量化,达到节能减排的目的,而且还可提高汽车发动机罩板的静态性能及与行人碰撞的安全性。In order to improve the energy saving and security of the automobile, and taking an automo- bile engine hood as prototype, the engine hood with aluminum foam is designed by ensuring light- weight and rigidity requirement. The static and pedestrian head impact protection performance of the two kinds of automobile engine hood is studied by FEM. The result shows that the automobile engine hood with aluminum foam not only can realize the lightweight so as to achieve energy conservation and emissions reduction, but also can improve the static performance and the pedestrian impact safety of the automobile engine hood significantly.
