摘　　要：运用流体动力学及非线性振动有关理论,针对矩形弹性壳液耦合系统受激励所产生的低阶大幅重力波的实验现象,建立了壳液耦合系统的运动方程组,用数值计算方法得到了重力波的时间历程曲线及幅频曲线,数值计算结果能较好地解释实验现象,并为研究此类问题提供了有效的方法。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.
