SOLID-LIQUID COUPLING MODAL ANALYSIS OF CYLINDRICAL TANK

In this paper, the coupling dynamic property of a cylindrical tank is analyzed by use of finite element method. A modal experiment about dynamic properties of the cylindrical tank is conducted It is shown that the theoretical hypothesis and the physical approximate process taken in the liquid-solid coupling analysis are reasonable and reliable, The results indicate that the liquid has a great effect on the dyntamic property of the tank structure . The more liquid there is in the
