摘　　要：瓦日线进行的C_(70E(H)-A)单元万吨重载列车试验,在紧急制动时纵向车钩力超限,文中对纵向力大值的产生原因进行了综合分析,从货车缓冲器性能、制动地点的线路情况以及车辆制动技术参数等方面进行了研究,分析了本次纵向力超限的关键因素,为后续试验提供参考。The C_(70E(H)-A) unit 10,000-ton heavy-haul train test carried out on on WaRi Railway line shows that the longitudinal coupler force exceeds the limit during emergency braking.This paper makes a comprehensive rootcause-analysis for the large longitudinal force,then studies the performance of freight car buffer,the line condition of braking place and the technical parameters of vehicle braking,and obtains the key factors of this large longitudinal force which provides references for the follow-up test.
