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.
