Vehicle Vibration Measurement on High-speed Railways

Abstract

Vehicle vibration is an important measurement item in catenary inspection on high-speed railways. However, it is a difficult task for the accurate measurement of vehicle vibration, due to the complicated dynamic vibration of trains relative to tracks on different inspection conditions. In this paper, the dynamic vehicle vibration and measurement model are analyzed in detail, and a measurement system is proposed based on the analysis results. The expected measurement accuracy is finally verified in experimental test.
