摘　　要：针对重载列车在平直道路上纵向力的作用情况及各个力的特征进行研究,提供了不同工况下列车纵向车钩力的计算方法,计算了紧急制动工况下的车辆车钩力。建立了由车钩连接的3节货车多自由度动力学计算模型,并将之前仿真计算所得车钩力加载至动力学计算模型,对列车曲线通过安全性做了研究分析,对目前重载长大列车在紧急制动状态下的曲线通过性能有一定的预测作用。The paper studies the case of longitudinal force on the heavy-haul train running on the straight track,provides the calculating method of train＇s coupling force under different cases,and also calculates the coupler forces under the emergency brake case.At the same time,a model which includes three wagons combined with developed coupler models is developed,and the previous result of simulation is picked up to the dynamic calculation model to have a study on the safety of curve pass,which can predict the train＇s curve negotiation performance under the emergency brake case.

关 键 词：纵向车钩力 缓冲器 曲线通过
