Abstract
The analysis carried out proves the existence of a correlation between changes in the values of diagnostic characteristics of flange thickness and height and flange steepness as a function of kilometrage. The intensity of wheel rim wear changes depending on the conditions in which the vehicle is operated. It is reasonable to assign vehicles to different routes so that the wheel rims wear evenly, eliminating the subsequent accumulation of repairs and wheelset replacements before repair at the P4 level. The wheelset diagnostic characteristics are not fully predictable, which makes it difficult to forecast their future values. However, the usefulness of the determined regression curves in the decision-making process concerning the renewal of the outer contour of the running wheels cannot be ruled out. Passive collection of wheelset diagnostic data is associated with the occurrence of numerous measurement errors affecting their overall usefulness. It is justified to introduce a system identifying these irregularities using archival measurements. It is advisable to undertake work on the change of identification of basic individual primary characteristics of the wheel external contour into primary characteristics of collective nature, as a result of which the probability of occurrence of non-uniformity of values of diagnostic characteristics on the wheel circumference could be limited and the phenomenon of occurrence of measurement errors could be minimised.
