Structural strength analysis of traction battery system

The structural strength of traction battery system is analyzed by using the finite element method. The stress or deformation distribution law of the traction battery system is obtained under various working conditions, including modal, vibration, impact, collision and extrusion. The purpose is to assess whether the structural strength of the traction battery system meets the standard requirements. The finite element model for the traction battery system is verified by the experimental results. The results show that the structural strength of the traction battery system meets the requirements, which verifies the rationality of the structural design of the traction battery system. Based on analysis results, the design optimization suggestions of the structure for the traction battery system are put forward.
