Structural Analysis of Battery Pack Box for New Energy Vehicles Based on the Application of Basic Foam Aluminum Materials

Abstract The box structure of the power battery pack is an important issue to ensure the safe driving of new energy vehicles, which required relatively better vibration resistance, shock resistance, and durability. Its structural safety is closely related to the life safety and property safety of drivers and passengers, which is an important index to the structural safety of new energy vehicles. In this work, the structure of the new energy vehicle is optimized by a finite element model, and the side crashworthiness applied to the electric vehicle is analyzed by means of a rigid column. To this end, the key components of the box structure of the battery pack box were optimized base on the application of foam aluminum material, which can effectively reduce the vehicle mass and improve vehicle safety.
