Abstract: In the design and development process of a blade electric vehicle, in order to meet the safety requirements of NVH and the whole vehicle and improve the comfort and satisfaction of the vehicle, the finite element model of the white body with the installation point of the rear sub-frame is established by CAE software, and the stiffness analysis is carried out. Based on the analysis results of CAE, the optimization scheme is put forward, and then the stiffness score of the optimization scheme is made. Finally, find out the best scheme to effectively improve the stiffness of the installation point of the rear sub-frame, meet the performance requirements, save the cost of product development, shorten the product development cycle, and provide an important basis for the improvement and optimization design of the rear sub-frame structure. Keywords: Rear subframe; Stiffness analysis; Optimum design; CAE

前言
后副车架作为汽车底盘结构的关键零部件，可以支撑前后车桥、悬挂[1]，可以显著提升驾驶操作性、乘坐安全性及舒适性等整车性能要求[2]。而后副车架安装点刚度作为评价整车操稳性能的重要指标，为满足NVH及整车安全要求，提高乘车舒适性及满意度，需要对后副车架安装点进行刚度分析。
门牌制作本文首先利用Hypermesh前处理软件建立某款纯电动汽车含后副车架的白车身有限元模型，转换格式后导入Nastran 软件进行刚度分析，最后再根据HyperView软件考察在产品设计初期是否满足设计需求，针对CAE分析结果提出五种优化方案，最终出能有效提高后副车架安装点刚度的最佳方
