A. Rovira, P. Salvador, J. Carballeira, F. Salas, "Wear created by the Wheel-Rail Contact in Different Rail Vehicles", in J. Pombo, (Editor), "Proceedings of the Second International Conference on Railway Technology: Research, Development and Maintenance", Civil-Comp Press, Stirlingshire, UK, Paper 180, 2014. doi:10.4203/ccp.104.180

Keywords: tribology of the wheel-rail contact, wear, profile evolution, levying of charges, variable coefficient of friction, railway maintenance costs.

Summary

Nowadays, new EU directives in the railway transport require that state owned companies manage independently the infrastructure, as network operators, and the rolling stock, as provision of transport services or train operating companies. Network operators should receive compensation in order to cover maintenance, operation, management and financial costs. In this paper it is calculated the wear produced by trains in the rail profiles, which is assumed to be proportional to the maintenance costs. Three different trains are studied: a high speed train, a commuter and a freight locomotive. The wheel-rail contact problem is solved using a variable coefficient of friction and friction laws identified from experimental measurements. Finally, the estimated values of the damage in the rail profiles are compared to the compensation costs projected by the regulation.
