An investigation to the combination effect of contact mechanics and operational aspect on the wheel wear rate and patterns of rail vehicles

Railway wheels are subject to high contact pressure and tangential stresses resulting in plastic deformation and wear. A series of activities is commonly employed by the operators to decrease the wear rate, though not addressing the hazardous failure mechanism of rolling contact fatigue (RCF). The present study has been focused on the running-in period, and on a procedure of bogie direction reversal (BDR) to show the importance of two domains of moving a wheelset, which are contact mechanics and operational aspect. The authors present wheel wear results within both flange and tread regions obtained in experimental work, which are then analysed.
