Abstract
Based on an elastic similarity model ( 1： 20 ) , the structural dynamic performance of hydraulic radial working gate is studied by the method of experimental modal analysis and ANSYS finite element method respectively. The study result shows that the modal frequency obtained from the calculation made by the ANSYS finite element method on the structure of the gate is well-coincided with the data got from the experimental modal analysis, and then the design of the gate structure is reasonable, and furthermore, the second order and third order modal frequencies of the structure have been basically separated from the range of the main frequency (0 ～ 3 Hz) of the flow-induced vibration, It is demonstrated that the ANSYS finite element method is an effective assistant tool for the conventional experiment method to calculate the dynamic performance of the structure of the radial gate.关键词
