Investigation on the Dynamic Characteristics of Track Slab with the Influence of Rail Corrugation
Publisher: ASCE
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 ...
Risk Assessment Method for High-Speed Railway Track Based on Dynamically Weighted Acceleration
Publisher: ASCE
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 ...
Risk Identification Method for High-Speed Railway Track Based on Track Quality Index and Time-Optimal Degree
Publisher: ASCE
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 ...
