Computer aided simulation analysis for wear investigation of railway wheel running surface

In railway applications wear prediction in the wheel-rail interface is a fundamental matter in order to study problems such as wheel lifespan and the evolution of vehicle dynamic characteristic with time. The change of the running surface of the railway wheels head has not only a great influence on the dynamic properties of the vehicle, but also a significant economical, safety and ecological impact in the process of the rail transport. One of the ways to predict these undesired situations are computer aided simulation analyzes. In this paper are presented results of wheel profile wear by Archard wear law, when the computational model of railway vehicle was driving in track by constant velocity. The vehicle was traveling along track where the rail profile was defined by standard (UIC 60 profile) with cant of 1:40, or the track profile really measured on the track, the profile S 91700_16 with the cant of 1:20. Simulations were realized by SIMPACK software.
