Experimental modal analysis on hydraulic radial gate

NIU Hai?feng,SONG Yi?le,HE Wen?juan(Department of Civil Engineering, Wuhan University, Wuhan 430072,China)  
Application of experimental modal analysis techniques in hydraulic structures remedies the defect produced by finite element calculating method by which a series of hypotheses and boundary conditions cant accord with the realities and provides the strong measure for treating engineering. This paper briefly presents the principle and experimental method of experimental modal analysis techniques,and a modal analysis to a working radial gate was conducted. The analysis reveals that: modal parameters of radial gate are not only under control of material properties in itself,but also influenced by operating mode; middle degree vibration occurs when the radial gate is operated in disadvantageous opening; in addition,there is a complex modal factor to a certain extent in the process of vibration.
