In this paper, we present a finite element multibody system model for the dynamics of vehicle-slab track application, and the preliminary validation is introduced of the track response. The model includes the multibody system model for vehicle, the finite element model for slab track, and the interaction part for the wheel-rail contact. Preliminary results on the track dynamic response from simulations and experiments are compared. The results show good agreement on the response of the track system, and the model can be applied for further co-simulation for vehicle track interaction investigations.
