The slip of a locomotive wheel is one of the sources of torsional vibration of the axle. Great efforts to prevent such vibration have been made by locomotive builders and railroads. But now they are trying to use this vibration in order to prevent slipping and to utilize adhesion. This paper describes the results of the experiments carried out on a test-rig which is a one-third scale model. An occurrence of vibration at the axle immediately before slipping is confirmed, and this vibration is common almost under all conditions. When the driving torque approaches the adhesion limit, the damping due characteristic near the adhesion limit decreases. Then axle-vibration can easily occur by the changing of the axle load and the traction coefficient. Experiments confirmed that this phenomenon can be used for adhesion control.
