摘　　要：根据空气流动理论和KZ1型控制阀原理,建立带有KZ1型控制阀的列车空气制动系统仿真模型,开发了对应软件系统。模拟了快速及普通位时单车制动、缓解和紧急制动,并与试验结果进行了对比,结果表明该模型能够较好地模拟单车制动性能。利用该程序预测装有该阀的快速货车制动性能,计算得出制动初速度为160 km/h,牵引总重不超过1 500 t的快速货车能满足制动距离的要求,运行安全。A freight car air brake system simulation model that is based on air flow dynamics and function principle of the KZ1 control valve is established. A series simulation result of single wagon, such as service brake application, release and emergency brake application, are given.The results show a good coherent with experiments data.Using this program, braking performance of rapid speed wagon train with KZ1 valve are predicted.It shows the rapid speed wagon will be able to satisfy the requests of the braking length with the trailing load of 1500 t at the initial braking speed of 160 km/h.
