摘　　要：测量了某越野汽车在定远汽车试验场和襄樊汽车试验场部分道路的道路载荷谱,根据统计学规律,应用LMS公司的TecWare软件进行数据处理。把时间序列转化为雨流矩阵,应用道路相关技术和雨流扩展技术得到两个试验场部分道路的当量关系,为在襄樊试验场复现定远试验场越野路提供依据。In this article, we have measured load spectrum of off-road vehicle in Xiangfan improved Proving Ground and Dingyuan improved Proving Ground. According as statistics principle, apply TecWare software of LMS Co. to analyse test data. First Convert Time series test data to rainflow matrix,then apply road CombiTrack and rainflow matrix Extrapolation to confirm correspond road correlation of two improved Proving Ground. Develop engineering test procedures in Xiangfan improved Proving Ground that can test vehicles to its durability design target that is defined based on Dingyuan improved Proving Ground off-road.
