ACCELEROMETER DEVICE FOR CONTINUOUS MEASUREMENT OF UNDULATING RAIL WEAR

MAREZZIMETRO: DISPOSITIVO ACCELEROMETRICO PER LA MISURA CONTINUA DELL'USURA ONDULATORIA DELLE ROTAIE

The Test and Technological Research Service of the Municipal Transport Undertaking of Milan has produced a simple device for the continuous meaurement of corrugation: it is based on the dynamic working of an accelerometer which follows the profile of the corrugation and records its depth graphically, with an error of a few hundredths of a millimeter. The device proceeds at a speed of 10 km/hr. To conciliate the requirements of the accelerometer and the related electronic instrument with the dynamic characteristics of the rail feeler, recourse had to be made to a modern piece of equipment for the reproduction of the vibrations in the laboratory. The device is, however, still in the experimental phase.
