| 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. |
