ASEA USES AXLE VIBRATION TO MEASURE CREEP AND OPTIMISE ADHESION

Investigation of the way slip takes place in driving wheels revealed that one wheel on an axle generally breaks into slip first, and this results in the development of torsional oscillations in the axle. This fact has been used on ASEA locomotives for a creep speed detection system, using a magneto-elastic transducer placed on the link which connects the gearbox to the bogie frame. The signal generated can be used directly to regulate the power supplied to the motor, and thereby increase the adhesion coefficient from 0.27 to 0.30.
