【Abstract】 With the rapid development of railway freight train braking technology,new types of control valves are constantly emerging,together train formation is expanding,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,establishment of virtual simulation model of braking system,research and development of interface equipment and control system,development of test bench for physical train braking performance and verification situation of test system are introduced.更多还原
