The reduction of wheels and rails wear is a very important factor in improving running safety and reducing maintenance cost. We conducted an experiment to clarify the mechanism of wear development by using 1/5 scaled rolling stock test stand which composed of wheelset and roller rings. We carried out the experiment under, different curving and friction conditions. In this paper, the influences of changing track curvature and coefficient of friction on wheel wear quantity are discussed. For each boundary condition, it is clarified that wear coefficient does not depend on travel distance. Also it is pointed out that the wear parameter changes extremely at the critical curvature.
