Anti-vibration safety performance research of battery pack based on finite element method in electric vehicle

The battery pack anti-vibration safety was analysed by structural intensity Finite Element Analytical Method and the battery pack intensity, stiffness and anti-vibration FEA model were established. As a guide of FEA calculation results, optimization design about battery pack inside and outside structure and welding method were used. The battery pack intensity, stiffness and anti-vibration safety performance were improved greatly. The test and simulation were proved that optimized battery pack should pass GB test and have excellent anti-vibration safety.
