| Abstract: | The paper is about the phenomenon of low-frequency and large-amplitude gravity waves of coupled liquid and elastic shell system, which are inspired with the exciting force. The modes of the liquid-elastic shell coupled system are analysed with FEM method; the results which draw from the analysis with FEM method are well constituent to the result of the experimentation. It verifies that the conclusion of the experimentation is reliable. |
