摘要：

To control the vibration of long-span cable-stayed bridge (LSCSB) caused by running train on metro line, vibration suppression effect of resilient wheel on the metro train-LSCSB coupled system is deeply investigated. Firstly, metro train-LSCSB system coupled dynamic model considering resilient wheels is formed. Then, the effects of resilient wheels on the dynamic characteristics of metro train-LSCSB system are investigated. Finally, the optimal stiffness ratiois determined, and the stiffness and damping of the resilient wheel are also optimized. Results show that: The resilient wheel reduces lateral vibration of LSCSB at 2-20 Hz. For the adopted metro train-LSCSB system, satisfactory vibration absorption effect can be obtained when stiffness ratio of the resilient wheel is 0.67-1. The optimal stiffness and damping of resilient wheel are recommended to be 30 MN/m and 300 kN.s/m.
