Technical diagnostics of tram undercarriages design, development and control

Abstract

The tram undercarriage is one of the most valuable tramway parts. It consists of Cardan drive shaft, final gear and wheels. On some models of the undercarriage there is additional reduction gearbox too. The general reconstruction of whole undercarriage is one of the important phases of tramway lifecycle. We were design and developed testing device and method for no-load diagnostics of tramway undercarriage. The passive forces are measured in low and mid speeds and vibration diagnostics is made too. The measured data are stored in data repository.
