摘要

摘要: 以某款车型前罩为研究对象，基于静态刚度与前罩外板弹性变形能力，通过材料替换与结构尺寸拓扑优化对前罩进行轻量化设计与分析，并通过与试验结果的对比，验证了前罩有限元仿真方法的准确性。轻量化设计的铝合金前罩满足了静态刚度以及外板弹性变形能力要求，减重效果达到47%。

Abstract: In order to meet the European pedestrian protection regulations for exportation and realize the vehicle lightweight design, the application of aluminum alloy hood is an effective approach to solve this problem. Taking the hood prototype of a sedan as an example, we conduct the lightweight design and analysis with light material substitution and structure dimension topology optimization. The test results show that the aluminum alloy hood with lightweight design satisfied the requirement of static stiffness and outer panel elastic deformation capacity, and the weight of the hood is reduced by 47%.
