Study on Dynamic Behaviour of Metro Train and Embedded Track System III：Dynamic Response Comparative Analysis of Embedded Track and Common Track

doi:10.3901/JME.2022.06.169

Abstract

Abstract: The application of embedded track in metro has the advantages of vibration and noise reduction and corrugation reduction. At present, there is a certain understanding of the dynamic behaviour of the embedded track, but the quantitative difference between the embedded track and the common track needs to be further explored. Based on the first embedded track test line used in metro of China, the dynamic vibration characteristics of the metro train-embedded track system and metro train-common track system were tested in same conditions. The difference of the track natural vibration characteristics, the operating stability and stationarity, and vibration characteristics of key parts of the track and the vehicle between embedded track and common track is compared. Based on the difference analysis, the practical application effect of embedded track in metro is evaluated. The research results provide a basis and reference for the practical application of embedded subway track.

Key words: embedded track, common track, metro train, dynamics behaviour
