Title: Vibration Analysis of a Bogie-Track System on Curved Tracks.
Abstract: Many researchers have studied the corrugation of railway track rails. It is thought that the corrugation is caused by the vibration and slippage of the rail or the wheelsets, but to date a detailed analysis of entire system has not been carried out. In this research, we divided the rails and sleepers into small elements and simulated a three dimensional vibration system. We compared results with those obtained from an actual curved track, and found that both sets of results were in agreement. Therefore we concluded that the vibration mode which cause corrugation in this case was the twisting and lateral bending vibration of the rail.
