摘　　要：新能源车减重100kg,续航里程将提升10%~11%,同时降低20%的电池成本和日常损耗成本,因此对于汽车的减重设计显得尤为重要。文章以新能源厢式货车货厢为研究对象,利用CATIA进行货厢模型设计,并将所建数模进行计算机辅助工程(CAE)分析,得出强度和模态等性能。从减少货厢顶盖骨加强筋和改变材料的角度来进行优化,通过ANSYS分析得出材料优化方案的减重比率为36%,结构优化方案的减重比率为11%,结构表明最优轻量化方案为材料轻量化方案。New energy vehicle weight loss of 100 kg,range will increase 10%~11%,while reducing 20%of the cost of battery and daily wear-and-tear costs,so it is particularly important for the vehicle weight loss design.This paper takes the new energy van compartment as the research object,it uses CATIA to design the cargo compartment model and conducts computer aidied engineering(CAE)analysis on the built digital model to obtain the strength and mode performance.The optimization is carried out from the angle of reducing the bone reinforcement of the cargo compartment roof and changing the material.Through ANSYS analysis,the weight loss ratio of material optimization scheme is 36%and the weight reduction ratio of the structure optimization scheme is 11%.Therefore,the optimal lightweight scheme is the material lightweight scheme.
