W. Kubin, W. Daves, S. Scheriau, "A Wheel-Rail Contact Model with Rough Surfaces", in , (Editors), "Proceedings of the Ninth International Conference on Engineering Computational Technology", Civil-Comp Press, Stirlingshire, UK, Paper 21, 2014. doi:10.4203/ccp.105.21

Keywords: surface roughness, asperities, contact, rolling, sliding.

Summary

A two-dimensional finite element model for the rolling contact of a wheel on a rail is presented that accounts for the roughness of the contact surfaces. A fully elasticplastic material description enables the computation of the heavily deformed layer observed in metallographic investigations of rolling sliding contacts. It can be shown that this layer is produced as a result of the contact of asperities and superimposes the contact mechanical deformation arising from the rolling sliding contact of flat surfaces. The roughness model is compared to a flat model and the prediction of the surface deformation is compared to metallographic investigations.
