A trailer car dynamics model considering brake rigging of a high-speed train and its application

Abstract Brake systems are essential for the speed regulation or braking of a high-speed train. The vehicle dynamic performance under condition is complex and directly affects reliability running safety. To reveal behaviour in process, comprehensive trailer car dynamics model (TCDM) considering brake established this paper. interactions between system other connected components achieved using disc–pad frictions, suspension systems, wheel–rail interactions. force motion transmission from to interface performed by proposed TCDM excited track irregularity. In addition, validity verified experimental test results. On basis, coupled simulated discussed. findings indicate that significantly including forces, wheelset torsional vibration, etc. within also affected vibration due Besides, developed can be further employed assessment such mechanical different conditions.
