FEM Analysis of Self-vibration Characteristics of Radial Gate with Box Structure

Sluice gate is wildly used in various water-retaining Structures,it is of great importance to the life and property safety of the people.when the gate is fully or partially opened,the vibration would occurs at the gate,even at the situation of closing the gate for water storage.Therefore,the dynamic characteristics and its corresponding response as well as the dynamic stability are significant problems which need urgent solution in hydraulic structure engineering.The self-vibration of one sluice gate in practical project is analyzed by using FEM software ANSYS.The results of vibration mode under two kinds of constraints are discussed.The data acquired from the FEM analysis is used to check whether the sluice gate is safe or not during its working period.
