Wheel/rail wear not only decreases running safety and stability, but also causes vibration and noise. However, measures against the wear require a great deal of cost and labor. In this study, numerical procedure using Multi-body Dynamics Software is proposed to predict the wear profile of rail in the curved section. In the curved section, the wheel passes with an attack angle, causing longitudinal and lateral slips at the wheel/rail contact patch. Longitudinal and lateral slips affect the wear development. Therefore, in this study, in order to research the influence for wear development when longitudinal and lateral slips occur simultaneously, we constructed numerical analysis model for wear prediction, and compared between the numerical and the experimental results.
