The prediction of wheel and rail wear is a very important problem in the railway field. The change of the shape of the wheel profile has not only a great influence on the dynamic properties of the vehicle (like stability, safety by passing curved tracks, etc.), the ride comfort of passengers and environmental insults, but also in terms of economics costs (plaining of maintenance interventions). One of the ways to predict these undesired conditions are computer aided simulation analyzes. In this article are presented results of wheel profile wear by Archard wear law, when the vehicle was driving in track by constant velocity. The vehicle was traveling along the track with the theoretical rail profile defined by standard (UIC 60 profile) with cant of 1:40 and the measured profile S 91700_16 with the cant of 1:20. Simulations were realized by SIMPACK software.
