| Abstract |
| | At the present time the bearing assembly of railway carriages cannot be tested without dismantling and reassembling. In the described method a piezoelectric probe is attached to the assembly. The signal from the probe when the wheels are rotating is passed through a low frequency filter and oscillograms are generated. Defective bearings produce a series of uniformly spaced spikes the amplitude of which is related to the size of the defect and the loading. Defective rollers are also shown up on the frequency spectrum of the probe output. The relationship between amplitude of the spikes and velocity at constant load is also determined.
