| 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. |

| Keywords: | electric vehicle battery box lightweight design carbon fiber composite multi-objective optimization |
