The gate often vibrates during opening and closing when it is partially opened, or even when it is closed when the water and the vibration may cause vibration damage to the gate when the vibration is severe, resulting in major water conservancy project safety accidents. Therefore, it is of great significance to study the vibration characteristics of hydraulic gates. The main content of this paper is respectively in the absence of water and water conditions, the use of ANSYS on the gate of the self-vibration characteristics of the comparative analysis, and based on a single fluid-solid coupling principle, the joint Fluent and Modal module, to analyze the gate in different openings under the work of the intrinsic frequency and intrinsic vibration pattern of the rule of change. It is of great significance to the construction of water conservancy projects.
