Finite Element Analysis and Optimization of Battery Pack Structure
A comprehensive simulation analysis was conducted on a power battery pack equipped with a liquid cooling system using finite element analysis software Hypermesh,ANSYS,and Star-CCM++.The modal characteristics,static strength,flow resistance,and flow field uniformity of the battery pack enclosure were analyzed.Based on the simulation results,the structure of the battery pack was optimized,including the topology of the module support frame,the optimization of the enclosure and the liquid cooling plate channels.The optimized model was subjected to static strength and extrusion simulation verification,and the results showed that the battery pack met the requirements in terms of safety and reliability,achieving a more reasonable and lightweight design.
