ACC (air cooled condenser) is widely used in coal-fired power plants. It has the advantages of water saving and energy saving, and the system is simple. The fan bridge is an important part of the ACC. At present, the vibration problem of the fan bridge is very much, and the experimental data of the bridge vibration is single, and the fundamental vibration source problem is not revealed. Therefore, it is important to study the vibration causes of the wind turbine bridge. This paper analyzes the possible causes of vibration of the fan bridge. Through the combination of field test and theoretical analysis, the main causes of bridge vibration are analyzed. Research shows that air disturbance is the main cause of bridge vibration. The research results provide basis for bridge design.
