LATERAL CREEPAGE AND ITS EFFECT ON WEAR IN RAIL WHEEL INTERFACE

Reduction of high rail and wheel replacement costs due to wear requires a better understanding of the complex processes taking place at the wheel/rail interface. These processes were studied as a function of yaw angle on a 1:10 scale apparatus modelling a wheelset riding on a pair of rail discs. Eight tests simulating straight and curved track were carried out at four values of yaw angles of 0', 8', 20', and 32', under lubricated and unlubricated conditions. The tests revealed a marked difference in wear mechanism and material response between lubricated and unlubricated cases as well as between high (outer) and low (inner) rails in the unlubricated case.
