摘　　要：新能源汽车的轻量化设计旨在减少汽车的整体重量,提高新能源汽车的能源利用效率,增加行驶里程,是实现其长期发展的重要途径。本文利用Solidworks建立新能源汽车轮毂模型,在分析其实际受力情况的基础上,运用Altair Inspire软件以最大化刚度为目标对其进行轻量化设计,得到三种不同设计方案的位移、安全系数和米塞斯等效应力值,对比分析优缺点后,选取最佳优化设计方案。优化分析结果显示,轮毂质量为7.409,较优化前减轻了10.2%,在满足轮毂强度要求和安全性的前提下,实现了轮毂的轻量化,为后续优化设计提供了参考。The lightweight design of new energy vehicles aims to reduce the overall weight of the vehicle,improve the energy utilization efficiency of new energy vehicles,and increase the driving range,which is an important way to achieve its long-term development.In this paper,Solidworks is used to establish a new energy vehicle hub model.Based on the analysis of its actual stress,the Altair inspire software was employed to perform lightweight design with maximum stiffness as the goal.The displacement,safety factor and Mises equivalent stress values of three different design schemes are obtained.After comparing and analyzing the advantages and disadvantages,the optimal design scheme is selected.The results of optimization analysis show that the hub mass is 7.409kg,which is reduced by 10.2%compared with before optimization.Under the premise of meeting the requirements of wheel hub strength and safety,the lightweight of wheel hub is realized,which provides a reference for the subsequent optimization design.
