Verification of Wavelength-Fixing Mechanism for Rail Corrugation Caused by Multiple-Wheel Interaction

This paper describes an investigation into rail corrugation wavelengths that can occur under various conditions. Corrugation is a periodic wear pattern that can develop on rail heads, causing significant problems to the wheel rail interface A theoretical model was used to predict corrugation growth by taking into account multiple wheel interaction and the Doppler effect of rail vibration resulting from wheel movement. Wheel-rail contact forces on the rail head were calculated, and the corrugation growth at an arbitrary wavelength was predicted. The study concluded that rail vibration interference excited by multiple wheels can result in different kinds of rail corrugation.
