ABSTRACT:
System for monitoring the angle-of-attack of the wheelsets of a railway vehicle moving along a track section. The apparatus includes a rangefinder to repeatedly measure at known intervals the instanteous distance between a reference point and successive registering points on a face plate surface of a wheel of a passing wheelset. A detector generates a signal representative of the velocity of the wheel passing along the reference point. A computer receives the output signals generated by the velocity sensor and of the rangefinder to compute the angle-of-attack of each wheelset.
