Abstract
The computation of the stress and strain of a rolling wheel on the rail requires the thorough analysis of the contact condition including slip. From the physical point of view it is important to use an appropriate description of the surface roughness and to take account of the rolling condition because this differs significantly from static contact. As a first approach a two dimensional model of a wheel running with constant velocity over an infinite elastic strip is investigated. Because of the necessity to use a dense mesh in the contact area and in order to avoid a transient computation it is advantageous to use an arbitrary Lagrangian Eulerian description (ALE). This paper contains a description of the ALE approach for the problem of the elastic-elastic contact of a wheel rolling with constant velocity over a rail of infinite length. The roughness of the surface is used in the formulation of a physically motivated penalty formulation and is exploited for the normal contact condition. The approach for tangential contact of rough surfaces according to Willners model is stated for completeness. A concept of an error estimator on the basis of the surface traction error as a criteria for the refinement of the mesh in the contact area is presented. As a numerical example the solution for a roller is presented in order to demonstrate the practicability of the introduced approach.
