Abstract

The concept of the rail damage function provides vital understanding of the operational performance of rail grades in terms of surface degradation. Previously, material specific damage functions have been derived from measurements in track combined with vehicle-track simulations. However, from the occurring wide range in track loading conditions it is difficult to achieve clear characterization results from track data only. To reach more controlled loading conditions, a rollingsliding two-disc laboratory set up could be applied. The validation of a two-disc test approach in order to define rail/wheel interface wear and RCF response is the topic of the here proposed study.
