| Abstract: | A dynamic analysis mode l is proposed for the train/track system supported on continuous elastic foundat ions. The track wave propagation problem under a high speed train is studied. T he influences of some parameters, such as rail surface irregularity wavelength, track mass, track rigidity and track viscosity, on the critical speed and the tr ack wave propagation are analyzed. |
