Dynamic Analysis ofTrack Wave Propagation Supported on Continuous Elastic Foundations

Publish Date: 25 Feb 2001

Abstract

Abstract

A dynamic analysis model is proposed for the train/track system supported on continuous elastic foundations. The track wave propagation problem under a high-speed train is studied. The influences of some parameters, such as rail surface irregularitywavelength, trackmass, track rigidity and track viscosity, on the critical speed and the track wave propagation are analyzed.
