Abstract:This paper is concerned with the numerical solution of the thermoelastic wheel-rail rolling contact problem including friction, frictional heat generation and transport across contact surface as well as wear. Three-layer model of rail material is assumed. Materials in upper and lower layers are characterized by distinct constant mechanical and thermal parameters. Middle layer material parameters are dependent on the depth of this layer according to the exponential law. The displacement and the temperature of the rail are governed by the coupled hyperbolic variational inequality of the second order and the parabolic equation, respectively. Using the special features of the rolling contact problem the original time dependent problem is transformed into the quasistatic elliptic problem and numerically solved. Distributions of stress and temperature fields in the contact zone are provided and discussed.
