摘要： 对某电动汽车的电池箱进行轻量化设计。因上箱体主要作为密封件,故采用结构优化的轻量化方案,而下箱体主要作为承载件,因而采用碳纤维替换原始材料的轻量化方案。在碳纤维结构下箱体的轻量化设计中引入了多目标优化算法。仿真结果表明,所采用的轻量化方案在减轻质量的同时,还有效提高了电池箱的刚度和模态频率。

Abstract: The lightweight design of the battery box of an electric vehicle is conducted. Since the uppercase is mainly for sealing, structural optimization is taken as its lightweighting scheme; while the lowercase acts as a load-bearing component, thus its lightweighting scheme is using carbon fiber to replace original material. In the lightweight design of lowercase, multi-objective optimization algorithm is introduced. The results of simulation show that the lightweighting schemes adopted not only reduce the mass of battery box, but also effectively increase its stiffness and modal frequency
