Finite Element Analysis and Topology Optimization Design of Seat Bracket for New Energy Bus

Abstract

This paper used NX8.0 to carry out the finite element analysis and topology optimization design of the electric bus seat bracket and the mechanical properties before and after optimization are compared. The results show that when the volume is reduced by 8.9%, the maximum deformation is reduced by 47.8%, the maximum stress is reduced by 66%, the average deformation is reduced by 50%, and the average stress is reduced by 54%. In this process, light weight is achieved, and the mechanical properties of the product are improved significantly. All processes are completed under the same software, which ensures the data consistency and editability. As the case involves new energy vehicles, parametric design, finite element analysis and topology optimization design, it is introduced into the CAE course as a project case under the background of "new engineering" and achieves good results.
