In wheel–rail contact, the locomotive adhesion variable characterizes the capability of the locomotive to convert available friction into traction at the interface. Recently developed AC (Alternating Current) drive induces a higher adhesion level compared to DC (Direct Current) drive. This can significantly affect the wheel–rail contact conditions such as high contact temperature due to the frictional...
In wheel/rail contact, rolling phenomenon on the curved track can be much more complicated than that on the straight track, especially on a sharp curved track. Due to the influences of super-elevation (also called track cant), angle of attack (AOA) and rail cant, stress states on the high rail are significantly different from that on the low rail. Therefore, the appearances of damages on the low and...
