Popis:	Authors analysed the rail dynamic models of rail vehicle and surveyed the features of the system “vehicle-track” modelling. Algorithms of creep forces calculation were examined. Four-axle freight wagon movement on the straight track and on curves corresponding to the given vertical and transversal track irregularities was modelled by software tool "Universal Mechanism". Authors examined the track stiffness influence on the vehicle moving stability/safety parameters at different speed, vehicle weight and track irregularities considering different wear rail profiles. Finally, basic conclusions and recommendations are given.
