Lightweight design and static strength analysis of battery box for electric vehicle
In this paper, the lightweight design and static strength analysis of electric vehicle battery box were replaced by composite materials instead of traditional metal materials. Firstly, the finite element model of the battery box was established by using ABAQUS. The battery box was geometrically cleaned, the composite material of the box structure and the foam material of the battery module were defined, and the grid was divided according to the process of finite element analysis. Then, based on the actual application, the boundary conditions were set and the load was applied to solve the problem. Finally, the stress and failure factor of the composite battery box under the sudden braking and sharp turn of the bumpy road were analyzed, and the strength of the battery box was checked. The results show that under the two combined conditions, the maximum stress of the battery box is less than the specified stress of the composite material, and the failure factor is much less than 1, meeting the strength requirements of the battery box.
