Modeling of wheel-track interaction with rail vibration damper and its application for suppressing short pitch rail corrugation

Abstract

Some kinds of short pitch rail corrugation are associated with the standing waves of rail vibration. These standing waves can be suppressed by rail vibration dampers, although they were originally developed to reduce the railway rolling noise via attenuation of the wave propagation in the rail. In this study the track models with rail dampers applied are introduced. Two kinds of wheel-track interaction, the single and multiple wheel-rail interaction, are studied to investigate the effects of the rail damper on the suppression of short pitch rail corrugation from the point of view of wheel-rail interaction force.
