The aim of the research is for a reasonable choice of wear coefficients for severe and mild phases in Archard's abrasive wear theory and friction coefficients for wheel flange and tread that correspond to conditions of Russian track for wheel profile wear modelling using dynamic models of wagons. This paper considers the gondola wagon on bogies model 18-9855 that are of the three-piece Barber S-2-R design. The wagon running test results on Experimental Loop Track in Scherbinka, the results of hardness measurements of wheel flange/tread and of wheel profile wear modelling are presented in this paper. In conclusion, a comparison of wheels wear of two freight wagons’ bogies (with friction and elastic-friction links of wheel sets with side frames) on the basis of specified wear model was carried out.
