摘要
在对重载货物列车钩的纵向随机压缩载荷工况分析的基础上，提出按货物车辆作业过程进行车钩随机压缩载荷的变程－频次统计分析方法，拟合推断出其母体概率分布，并依此编制出车钩压缩程序载荷谱。结合此方法，编制了我国重载货物列车（５０００ｔ级）车钩压缩程序载荷谱。
At the foundation of working condition analysis of the random lengthway compress load of the heavy haul freight train coupler, a statisticeal analysis method of the coupler load change-frequency is introduced during the freight car's working process,which stimulates the matrix probability distribution and combined which,the coupler compress load spectrum of the heavy haul freight train (5000 t) of our country is drawn up.
