摘　　要：纵向冲动是影响大秦线重载组合列车运行安全的关键因素。分别利用全真制动试验台和列车空气制动与纵向力学仿真系统,开展2万t重载组合列车充排风试验和初制调速列车纵向力仿真试验,根据试验结果分析充排风特性对列车纵向力的影响。Longitudinal impulse is the key factor affecting the operation safety of heavy-haul combined trains on Daqin Line.The full braking test bench and the train air braking and longitudinal mechanics simulation system were used to carry out the air charging and exhaust test of the 20,000-ton heavy load combined train and the longitudinal force simulation test of the initial speed regulating train,and the influence of air charging and exhaust characteristics on the longitudinal force of the train was analyzed according to the test results.
