摘　　要：针对某型新开发的电动汽车减速器箱体进进行了优化设计分析。首先,在对减速器各轴承、轴等零件的受力分析的基础上,确定了箱体的载荷分布,进而进行了有限元应力应变分析。根据有限元分析结果,对箱体局部区域以箱体材料体积为目标函数、在刚度和强度为约束条件的情况下进行了结构拓扑优化。根据优化结果,综合考虑箱体的实际工作情况和相应功能要求,修改箱体结构,得到减重后的箱体模型。结果证实,优化后的箱体结构刚度基本不变,而强度有所增加,重量减轻了大约6%。A finite element stress strain analysis is performed to the reducer box, according to the results of finite element analysis, local to the material volume as objective function, the stiffness and strength as constraint conditions for structural topology optimization. According to the optimization results, considering the actual situation and the corre- sponding box body functional requirements, modifying body structure, obtained the box model with lighter weight. The results show that, after the optimization of the structure of the box body stiffness basically unchanged, intensity in- creased, reducing the weight of the approximately 6%.
