摘　　要：文章探讨了车辆在上汽大众试车场与德国大众Ehra试车场进行道路试验时所承受的载荷关系。通过在测试车上安装六分力测量轮系统,分别采集两个试车场的道路载荷谱信号,依据疲劳损伤理论,对比了车辆在两个试车场中测得的载荷差异。同时分析了车辆在道路试验中所承受的载荷的影响因素,并提出了上汽大众试车场的交变耐久道路试验的优化方案。In this paper,the vehicle's road load relationship between SAIC Volkswagen's Proving Ground(PG)and Ehra's is analyzed.The road load spectrums signals of two PGs are collected by the wheel force transducers.According to fatigue damage accumulation theory,these two PGs'road load test results are compared.In addition,the influence factors of vehicle's road load are analyzed,and an optimum method of road test in SAIC Volkswagen PG is proposed.
