Research on the prediction method for the three-dimensional wear state of the polygon wheel

Polygonized wear of wheel is a three-dimensional wear state which includes circumferential periodic wear and lateral hollow wear. When polygonized wear of wheel occurs, wheel-rail dynamic characteristics will be affected and the subsequent wear distribution of the wheel will be influenced. To study this phenomenon, a prediction method for the three-dimensional wheel wear state is put forward and a united simulation model is established in this paper. Based on this model, wheelset vibration characteristics, wheel-rail contact characteristics, and wheel wear characteristics were analyzed. The results show that when considering three-dimensional wear state of wheel, the stress distribution in the wheel-rail contact patch is affected by the coupling of the lateral and vertical vibration caused by the polygonized wheel, which in turn affects longitudinal and lateral creep force and creepage distribution in the contact patch. Then, the distribution of circumferential and lateral wear on the wheel will be changed. Finally, the three-dimensional polygonized wear of wheel with different wear depths and widths at different wheel phase angles will be formed.
