Abstract: The research status of rail corrugation and the existing theoretical model are reviewed. A rail corrugation model based on vehicle/non-ballast track is established, in the combination of the rigid-flexible coupled vehicle/track model, the modified non-Hertzian rolling contact theory of wheel/rail, material wear model and wear accumulation model. Some factors, such as the flexibility of rail and slab, the discrete support condition of rail pad, are considered in the rigid-flexible coupled vehicle/track model. The effect of rail corrugation on the wheel/rail contact is taken into account in the modified non-Hertzian rolling contact model. The contribution of spin to wear is considered in the wear model. The rail corrugation model can consider not only the effect of wheel/rail transient dynamic interaction on the formation and development of corrugation, but also the effect of the accumulated corrugation on the wheel/rail contact and coupling dynamics. And it can predict the rail corrugation caused by the 8 pair's wheel-rail interaction of the whole vehicle. The present model was used to reproduce the initial evolution of residual corrugation. A theoretical basis and technical support are provided for the mitigation of rail corrugation.
