本文提出了一种精确而简便的计算方法，可用于计算对底板部分上抬的圆筒形储罐的摇摆运动有贡献的流体质量，即摇摆运动的有效流体质量、摇摆-胀形相互作用的有效流体质量、摇摆运动的有效流体惯性矩及其质心。由于月牙形隆起引起的罐底板的不对称变形被用来将质量的量化从严格的处理中分离出来。本研究将圆柱形储罐视为一组薄矩形储罐，即所谓的切片模型，并将它们垂直于储罐岩石运动的旋转轴。然后求解由罐底板的上提及其位置确定的各切片模型的边值问题，将引起圆筒形储罐摇摆的流体质量量化为各切片模型的流体质量之和。给出了在不同的罐底板隆起宽度与罐直径比值下，液体摇摆运动的有效质量、液体摇摆-膨胀相互作用的有效质量、液体摇摆运动的有效惯性矩及其质心随罐的几何形状的变化关系。
Accurate and easy calculation of the mass of fluid contributing to the rocking motion of cylindrical tanks with partial uplift of bottom plate, which is the effective mass of fluid for rocking motion, that for rocking-bulging interaction, effective moment inertia of fluid for rocking motion and their centroid, is proposed. Asymmetric deformation of the tank bottom plate due to crescent-like uplift is used to put quantification of the masses away from rigorous treatments. This study considers the cylindrical tank as a set of thin rectangular tanks, so-called a slice model, and puts them perpendicular to the rotational axis of the tank rock motion. Then solve a boundary-value problem of each slice model specified by uplift of the tank bottom plate and its location, the mass of fluid contributing to rocking of cylindrical tanks is quantified as the sum of that of each slice model. Values of the effective mass of fluid for rocking motion, that for rocking-bulging interaction, effective moment inertia of fluid for rocking motion and their centroid are tabulated and depicted as a function of the aspect of tanks for different values of the ratio of the uplift width of the tank bottom plate to the diameter of tank.
