Time-Frequency Analysis Study on Picking-up Dynamic Response Characteristic on High Speed Train wheel-track Coupling System

摘要：

In this article, the vehicle track system vibration responses on different speeds are calculated based on incentive model of track irregularities and corrugations on different wave lengths. The vibration response data of high speed vehicle-track system was empirical mode decomposed with the improved EMD method and systems each dynamic character was picked up. Also wheel force and acceleration intrinsic modes were analyzed and compared. After all these studies, the result indicates that improved EMD method could decompose the vibration signals as incentive models adaptively and pick up the dynamic characteristic of the vehicle track system efficiently.
