The complete model of locomotive and vehicle and the exact motion equations of wheel-set are established, in which, three-dimension wheel/rail contact geometry is taken into account and the Kalker's creep theory is employed to analyze the effects of the contact region of wheel/rail. An iterative procedure of solving wheel/rail creep force is proposed to improve the existed calculating method. Finally, the motion equations of vehicle with 23 DOFs are derived using the D'Alembert principle.
