and conventional train braking performance test equipment can no longer meet the development needs.Introducing computer virtual simulation technology to explore intelligent test methods and equipment for train braking performance is an inevitable approach towards improving test research capabilities.New idea of semi-physical simulation test of train braking performance based on the combination of virtual simulation technology and physical test bed is proposed.Semi-physical simulation test method and technical scheme， With the rapid development of railway freight train braking technology，together train formation is expanding，research and development of interface equipment and control system，介绍了半实物仿真试验方法及技术计划、制动系统虚拟仿真模型建设、接口办法及控制系统研发、实物列车制动性能试验台研制及试验系统试验验证状况，提出了基于虚拟仿真技术与实物试验台相联结的列车制动性能半实物仿真试验新思路， 摘要 随着铁路货车制动技术快捷开展，列车编组辆数一直增多，新型控制阀一直涌现，摸索列车制动性能智能化试验方法及配备，股权分配，establishment of virtual simulation model of braking system，new types of control valves are constantly emerging，是提升试验钻研才华的必由之路。

development of test bench for physical train braking performance and verification situation of test system are introduced. 。

传统的列车制动性能试验办法已经不能满意开展必要，引入计算机虚拟仿真技术，。
