Analysis of Vibration Mode of Hydraulic Gate Structure

Abstract:

It is generally existed that the vibration problem of hydraulic gate structure during water conservancy project, whose vibratory magnitude is closely related to inherent feature of gate structure and spectrum signature of hydrodynamic loads. In this project, through contrastive analysis of modal test procedure of multi-support excitation and single-point response as well as finite element computational analysis, test model and finite element model of some hydraulic sector gate had been built to indicate the results of modal test were basically close with that of finite element model, the changing frequency being the same. Both of them could truly reflect the dynamic characteristics of gate, which proved it effective that the methods for researching on vibration modes of hydraulic gate adopted and provided important basis for further dynamics research and design optimization.
