摘　　要：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,运用非线性振动有关理论,对已建立了壳液耦合系统的运动方程组用平均法得到了其解析解,并与数值解进行了比较,其结果吻合较好,更好地解释了实验现象。According to non-linear dynamics theory, in allusion to the phenomenon of large-amplitude and low-frequency gravity waves in the rectangular elastic fluid-shell coupled system that was stimulated, the analytical solution of the constructed equations was obtained by averaging methods. The analytical solution was compared with the numerical analysis results, it is shown that the analytical solution can interpret the phenomenon of the test well.
