A time-domain model for high frequency wheel-rail interaction considering the effect of flexible wheel and track is developed, the wheel-rail contact coupling between normal and tangential dynamics. Firstly, the impulse response functions of the wheel-rail structure are solved by using modal superposition method, and the wheel/rail flexible vibration responses are calculated by using the convolution with the wheel-rail contact force and the impulse response function that are calculated in advance. Then high frequency wheel-rail normal and tangential interaction forces are calculated and shown in the time domain with revised non-Hertzian contact theory, in which the effects of wheel-rail stick–slip oscillation in contact patch are considered.
