Abstract: Aiming at the problems of high energy consumption and limited load capacity caused by the heavy weight of traction battery frames, this paper proposes a lightweight design method. Through modal sensitivity analysis, this study achieves a 20% reduction in the frame's self-weight while maintaining its strength and performance, by adjusting the thickness of the main structural components. This lightweight method provides an efficient solution for the lightweight design of new energy commercial vehicles, and is of great significance for enhancing their economic efficiency and market competitiveness.
