Analysis of Tracked Vehicle Vibration Response Considering the Track Circuit Vibration

Abstract

To accurately describe the vehicle vibration, the vibration response of the vehicle operation system affected by the track was studied. Through the analysis of the topological structure of vehicle operation system, the flexible track model and the rigid track model was built up. The track circuit model was established by simplifying the rigid track, and its inherent vibration was calculated by eigenvalue analysis. Power spectrum method was used to compare the dynamic model of flexible track and the dynamic model of rigid track and verify the effect of track on the vibration of vehicle. The results show that the effect of track on the vibration of vehicle mainly include the inherent vibration of track circuit and the high frequency vibration related to track pitch; the computing result provides a reference basis for describing the effect of track quantitatively.
