The paper is devoted to dynamical analysis of a railway vehicle motion along a direct waved railway. A mathematical model of this discrete multibody system that consists of vehicle case and two bogies with double suspension is created. The exact time change of a wheel-rail contact point position during vehicle motion, when a wheel carries out a general spatial motion, is included into the model. The variable creep force effects between wheels and rails are supposed to be nonlinear according to Kalker’s theory. The rails and vehicle wheels are interconnected through the contact creep elements. The whole vehicle is excited by rail irregularities. Numerical solution and graphical visualization of the vehicle motion with the constant forward velocity is performed.
