Abstract
Under conditions of curve negotiating and hunting, lateral force is generated at the wheel/rail interface that can damage the wheel tread. The rolling contact tests were performed on a JD-1 wheel/rail simulation apparatus with different lateral forces between the rail and wheel rollers. The results indicate that plastic deformation and mild wear dominated at each side of the contact area, while fatigue damage dominated at the middle region. Drastic changes in stress and stress direction from the high stress region to the lower stress region can lead to plastic accumulation and the initiation of fatigue cracks. The formation and breaking of metal tongue make big contribution to material loss in this condition.
