摘　　要：本文针对圆柱形盛液容器受高频激振产生低频大幅重力波的现象,用有限元法对圆柱形弹性壳体及壳液耦合系统进行了模态分析,得到了壳液耦合系统的主要振型;用有限元法分析所得的模态结果与实验现象及实验模态分析结果有较好的吻合,进一步验证了实验结论的可靠性。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.
