THE INFLUENCE OF OPERATING CONDITIONS ON SELECTED PROPERTIES OF THE SURFACE LAYER OF THE RAILS AND WHEELS OF TRAMS
Journal Title: Tribologia - Year 2015, Vol 263, Issue 5
Abstract
The paper presents the results of research on the hardness and surface geometric structure of selected surfaces of the wheels and rails of a tram system. Vehicles whose rims were examined belonged to the Municipal Transport Company in Poznan Ltd. The study showed the impact of the exploitation process on the strength of the surface layer of the rim and the tested rails and of running surface roughness changes with respect to the top of the rim during operation.
