高柔性膜与流体的相互作用问题在各个行业中都是非常重要的。在本文中，我们考虑了二维矩形储罐，其表面被橡胶膜覆盖，并研究了其行为，以估计相互作用行为。膜被假定为包含材料和几何非线性的Ogden类橡胶膜。流体是水，假定为势流。我们考虑了在水平正弦加速度作用下的时程响应，这对大多数实际应用是很重要的。采用任意拉格朗日-欧拉有限元方法考虑流体的运动边界，计算了固有频率附近的变形膜面、应力分布、流动方式等行为，并进行了讨论。在这些数值算例中，除了在界面附近观察到类似于液体晃动的行为外，尽管由于膜盖的存在而没有自由面，但是在界面附近观察到了类似于液体晃动的行为。因此，可以发现，

The interaction problem of highly flexible membrane and fluid are very important in various industries. In this paper we consider the two dimensional rectangular tank filled with a fluid of which surface is covered by a rubber membrane, and investigate its behavior in order to estimate the interaction behavior. The membrane is assumed to be the Ogden's rubberlike membrane which includes material and geometrical nonlinearities. The fluid is water and assumed to be potential flow. We consider the time historical response subjected to horizontal sinusoidal acceleration which is important to the most of practical usage. The arbitrary Lagrangian-Eulerian finite element method is employed to take account of the moving boundary of the fluid Behavior such as deformed membrane profile, stress distribution, manner of flow and so on are calculatedin the vicinity of natural frequency and discussed. In these numerical examples, the similar behavior to liquid sloshing is observed except for in the neighborhood of the interface, although there is no free surface because of the existence of the membrane cover. Thus it is found that the
