摘要

摘要: 为了提高汽车的环保性、安全性，以某汽车顶板为设计原型，以轻量化为约束条件，设计泡沫铝夹芯结构汽车顶板。然后，利用Ansys软件对两种结构汽车顶板的静态性能和高空坠物、倾翻安全性做仿真分析。结果表明，泡沫铝夹芯结构汽车顶板与原型结构汽车顶板相比，其质量减轻了32.68%，静态载荷作用下的最大应力和最大位移均减少20%，高空坠物、倾翻试验中，最大应力分别减少5.92%和27.78%，最大位移分别减少35.91%和20.67%，表明泡沫铝夹芯结构汽车顶板不仅实现了汽车轻量化达到了节能减排的目的，而且提高了汽车的安全性。

Abstract: In order to protect the environment and enhance the car's safety, we take the car roof as the design prototype and design the car roof of aluminum foam sandwich structure, taking into account its lightweight condition. We use the Ansys to do safety analysis of two kinds of the car roof's static performance of falling objects and tipping. The analysis results show that the weight of the car roof of aluminum foam sandwich structure decreases by 32.68% compared with the car roof of prototype structure. In static loading, maximum stress and maximal displacement decreases by 20%. The experiments on falling objects and tipping show that the maximum stress decreases by 5.92% and 27.78% respectively and that the maximal displacement decreases by 35.91% and 20.67% respectively. The car roof of aluminum foam sandwich structure not only realizes the lightweight for energy conservation and emissions reduction but also enhances the car's safety.
