Characteristics of liquid sloshing in a partially filled rectangular tank supported by Pendulum

为了提高悬浮容器中液体运输的安全性和效率，有必要弄清容器和内部液体运动的基本特性。本文研究了摆支承的矩形贮箱在水平激励下与贮箱中液体的非线性耦合振动特性，解析地给出了摆支承的矩形贮箱中液体运动由二维液体运动过渡到三维液体运动的条件，并通过实验加以验证。此外，通过实验发现，根据条件发生几乎周期性的振动，并通过分析确认了这一点。

In order to enhance safety and efficiency of transportation of liquid in a suspended container, it is necessary to clarify basic characteristics of the movement of the container and the liquid inside. This research pays attention to the characteristics of nonlinear coupled oscillation of a rectangular tank supported by a pendulum subject to horizontal excitation and liquid contained in it. We analytically projected conditions under which liquid motion of a rectangular tank supported by pendulum transits from two-dimensional liquid motion to three-dimensional liquid motion and confirmed the conditions by experiments. Moreover, it was experimentally found that almost periodic vibration occurs depending on conditions and this was analytically confirmed.
