VIBRATION AND NOISE OF MODEL WHEEL DUE TO TREAD ROUGHNESS

As railway vehicles travel on the rail, the following kinds of wheel/rail interaction noise are generated. (1) Squeal noise when a wheel rolls on a curve, (2) impact noise by flats of the wheel tread, (3) rolling noise by the roughness on the contact surfaces of the wheel and the rail when the wheel rolls on the rail. Of these the noise of (3) is the most significant. Hitherto, many studies on the characteristics of wheel vibration, squeal noise, impact noise of flats have been carried out. But studies on the rolling noise generated by the surface roughness of the tread of the wheel and those of the rail-head were few. Therefore, the authors paid attention to the relationship between the roughness and the rolling noise, and aimed to investigate how the roughness contributes to the rolling noise. For that purpose, experiments using an experimental apparatus were carried out and the vibration characteristics of a model wheel were studied theoretically.
