Abstract: Rail corrugation, a common defect of rails, causes a high frequency self-oscillation effect in track slabs when there is an external load. In order to analyze the influence of multi-scales of rail corrugation on the dynamic ...

Abstract: Wheel faults are the main causes of safety issues in railway vehicles. The modeling and analysis of wheel faults is crucial for determining and studying the dynamic characteristics of railway vehicles under variable speed ...

Abstract: As railway maintenance increasingly requires strict inspection and accurate repair, it is urgent to establish a reasonable assessment method for identifying the risks in high-speed railways. Severe track irregularities can ...

Abstract: The real-time identification and early warning of the state of the track are significant to keep the high-speed railway (HSR) safe, stable, and comfortable. This paper proposes a new risk identification method based on the ...
