The paper deals with the numerical solution of a class of rolling contact problems with the temperature fields as an additional component. The wheel-rail system serves as an example. We consider contact with Coulomb friction between the rigid wheel and an elastic rail fixed to a rigid fundation. We assume a frictional heat generation and heat transfer through the contact area. In the paper we propose a quasistatic approach to solve this contact problem. The system is described by an elliptic variational inequality and a parabolic equation. To solve this problem numerically we will decouple it into mechanical and thermal parts. Numerical examples showing the influence of the temperature field on the normal contact force distribution and the length of the contact zone are provided.
