摘　　要：针对汽车车轮冲击试验,通过动态响应有限元分析,确定车轮结构中的最大应力及危险位置,并通过实验应力分析,利用动态电阻应变仪等,测定并计算车轮结构中关键点的应力响应,利用MATLAB计算并绘制Von Mises应力响应曲线。通过对比有限元分析与实测结果,提出修正系数,对有限元分析模型进行修正,该结果可用于企业的车轮设计,提高产品结构设计的一次合格率。Aimed at the impact test of aluminum alloy automobile wheels , the maximum stress and dangerous area in the wheel structure are determined through dynamic response finite element analysis.And the stress response at the key point in the wheel structure is measured through experimental stress analysis by dynamic resistance strain gauges .Then using MATLAB the Von Mises stress is calculated and the stress response curve is drawn .Comparing the calculated Von Mises stress and the measured one a cor-rection factor is proposed to correct the finite element analysis model , and this result can be used in the wheel design in the enter-prise to improve the once qualified rate of product structure design .
