Rail Corrugation Characteristics Deduced from a Wavelet Analysis of High-Speed Train Interior Noise and Vibration

A method to deduce the characteristics of rail corrugation was developed and presented in this paper.It has been found that noise and vibration in the train vehicle were primarily contributed by rail corrugation and wheel polygonalisation.As the characteristics of wheel sets of a particular train can be assumed to be unchanged during a trip, rail c
