摘要：
In order to prove the adaptability of the metro train-bridge（especially long-span bridge）system to resilient wheels from the perspective of dynamics，the influence of resilient wheels on the long-span cable-stayed bridge （LSCSB） on the vibration of the metro train-bridge system and its suppression characteristics was studied. Based on the vehicle-track coupling dynamics theory，a coupled dynamic model of metro train-LSCSB system considering resilient wheel was established. Adopting the model，the effect of resilient wheels on the vibration characteristics of metro train and LSCSB under the combined disturbance of long-short wave irregularities was studied，the damping effect of resilient wheel on metro train-LSCSB system is proved from time-frequency domain. The results show that when metro train running through，the resilient wheel can effectively reduce the wheel/rail force，vibration of the wheel and axle box. Compared with the traditional rigid wheel，the vibration of rim is the most intense，followed by the vibration of traditional rigid wheel，and the vibration of web is the smallest. Based on the propesd dynamic parameters of the resilient wheel，the excellent frequency of the resilient wheel vibration is concentrated in 10 Hz to 50 Hz，and there is a peak around 25 Hz. The main frequency of the bridge vertical and lateral vibration is about 1 Hz. The resilient wheels can effectively reduce the mid-low frequency vibrations of LSCSB. © 2023 Editorial Board of Jilin University. All rights reserved.
