Abstract
Field measurements have been carried out using a series of railway wheels with specially machined running surfaces. These were given a sinusoidal profile around their circumference. This allows accurate measurements of noise and vibration to be made for single frequency excitation. A series of wheels with different wavelengths has been used in combination with a range of running speeds to allow a wide frequency range to be scanned. Results are compared with predictions using a theoretical model in order to investigate a number of detailed aspects of the model. The predicted behaviour has been confirmed in terms of the magnitude of the response of the track and the wheel and the apparent damping of the wheel during rolling. An experimental estimate of the filtering introduced by the finite contact patch length is also possible.
