WSP(wheel slide protection) system shall be verified through lots of test results of railway vehicle on field at various running environment because WSP system is essential component for vehicle safety. But a new component or new developed subsystem is not easy to be tested on the real field test of railway vehicle in the view of risk management and test cost, particularly for components for brake system. And therefore HILS(hardware-in-loop simulation) of WSP with vehicle dynamic is considered as the solution. A railway vehicle in HILS is to be realized as real-time simulation and the wheel rail contact model shall be included on vehicle model, which can generate creep force similar to actual force. To make accurate contact forces the contact model shall represent the effects of a size of contact patch, contamination of contact surface and running speed, as input parameters. On this study the contact model for HILS for WSP system is to be realized as real-time vehicle simulation, which can represent phenomena of sliding at braking on contaminated rail. Then predefined running scenario will be simulated and the results are to be reviewed for validation of contact model.
