双铰底板闸室结构动力特性研究

ccording to Ansys program, this paper gives a modal analysis on sluice structure with double-hinged sole plate,in order to analyse the effects of hydrodynamic pressure and different stations of the double hinges to the dynamic characteristics of this structure.Meanwhile,it gives a study compared to the unitary sluice structure.The results of calculation show that the hydrodynamic pressure and different stations of the double hinges have a little influence to the frequencies of sluice structure with double-hinged sole plate,and the frequencies of unitary sluice structure is less.
