Abstract

The condition of the wheels of a train was evaluated using vibration analysis techniques. The bogies of the train were instrumented with accelerometers. Vibration was sampled on-board both in good and deteriorated condition. Analysis of acquired signals was then performed in order to correlate signal characteristics with wheel defects. The high frequency spectrum showed a significant increase of energy content in the deteriorated condition but could not be directly correlated with wheel flats. The low frequency spectrum of the demodulated acceleration signal was proved to be a suitable transformation that could directly relate wheel flats to signal characteristics producing a spectrum with a characteristic spike at 1 wheel revolution (1X) which is directly related with wheel flat impact on rail.
