摘　　要：轮毂电机因其具有传动结构简单,传动效率高等特点广泛应用于新能源汽车中。针对轮毂电机簧下质量增加的难题,开展了对轮毂电机壳体轻量化设计的研究。本文通过对传统轮毂电机与转向节进行受力分析,以一种新的壳体集成方式去解决在有限的轮内空间内增加轮毂电机的尺寸,并在此基础上通过Hypermesh仿真软件对模型进行轻量化设计,优化了壳体的应力分布、消除了部分结构的应力集中现象、整体质量减轻49.29%,优化效果明显。Hub motors have independent drive characteristics and high transmission efficiency,and have been widely used in new energy vehicles.Aiming at the problem of increasing the unsprang mass of hub motors,the lightweight design of hub motor shells was studied.In this paper,the force analysis of traditional hub motor and steering knuckle is carried out,and a new shell integration method is used to solve the problem of increasing the size of the hub motor in the limited space of the wheel.And on this basis,the model is designed lightly by Hypermesh simulation software,the stress distribution of the shell is optimized,the stress concentration phenomenon of some structures is eliminated,and the overall mass is reduced by 49.29%,and the optimization effect is obvious.
