摘　　要： 将动车的运行状态按其运行交路区分.选取其上某一载荷,计算载荷对某一假设的理想点造成的当量损伤及寿命,求解每一交路上能获得高置信度测试结果的最少测试次数,确定最能够代表该交路运行状态的典型测试数据,将各交路的典型数据处理并比较,最终获得能代表动车整个运行状态的最有效测试数据,处理最有效数据得到该载荷的最有效载荷谱. The EMU＇s running status was distinguished with its＇ routes in this paper.The minimum number of tests which high confidence results of every route can get was solved,and the typical test data which can represent the status of the route effectively were get.Then the typical data of every route were dealt and compared each other,and the best test data which can represent all status of the EMU were get.After these best data were dealt,the best load spectrum of the load on EMU were get in the end.

关 键 词： 动车组 载荷谱 高置信度 组合分布 交路
