Spatial Coupling Vibration of Vehicle-Track-Bridge System due to Different Track Irregularities

Abstract:

Article Preview

Track irregularity is one of the most important factors that induce vehicle-track-bridge coupling vibration. In this paper, spatial model of vehicle- track-bridge system is established. The track irregularity sample in time domain are established by power spectrum density and taken as the exciting source to analyze the spatial coupling vibration of vehicle-track-bridge system. By comparing the vibration responses of the model excited by vertical profile irregularity and the model excited by four different irregularities, the change of track irregularities have mostly influence on the vibration of the parts above the rail and nearly no influence on the parts under the rail and bridge.
