英文摘要：

Based on hydromechanical and non-linear dynamics theory,a set of equations were constructed according to the phenomenon of large-amplitude and low-frequency gravity waves in the rectangular elastic fluid-shell coupled system that was stimulated,the time history curves and frequency spectrum curves were obtained by numerical methods.The numerical analysis results interpreted the phenomenon of the test well,which offers a powerful evidence for researching gravity waves of fluid-shell coupled system.
