Abstract

In this paper, according to the design requirements of the battery cabin and the structure of the frame, the finite element model is established. The static analysis and constrained modal analysis are carried out for the battery cabin under two extreme conditions of bumpy sharp turn and bumpy emergency braking, and the first six modal frequencies and modes are obtained. The optimized battery cabin achieves the goal of 2% lightweight optimization design, and other performances are satisfied. After the topography optimization, the endurance and rigidity of the battery cabin are improved to varying degrees. The elastic limit of the material is much higher than the maximum stress. The weight of the battery cabin is reduced by 2.5% through topology design.
