Comparing dynamic performance between new sleeper-damping and floating-slab track system
Highlights A new sleeper-damping track with elastic side-supporting pad (SDTESSP) was proposed. Comparing dynamic performance between new sleeper-damping and floating-slab track. The damping capacity of the SDTESSP can be close to that of the FST.
Abstract Vibration induced by urban rail transit has become a global public concern. To reduce the vibration, a new Sleeper Damping Track with Elastic Side-Supporting Pads (SDTESSP) was proposed. To evaluate the dynamic performance of the SDTESSP, a spatial model of train-SDTESSP coupled dynamic and a finite element model of the track-tunnel-soil system were developed. Field tests were conducted to validate the models, and there is good agreement in both the time and frequency domains. Furthermore, the vibrationtransmissibility of the SDTESSP, train-SDTESSP coupled interaction, and train-induced environmental vibration were investigated by comparing it with the Floating-Slab Track (FST). The results indicate that the damping capacity of the SDTESSP can be close to that of the FST by adjusting the material parameters of the elastic side-supporting pads.
