- 論文の詳細を見る
As an effective antisloshing device, a reversed U-tube was investigated as a dynamic damper and its suppression characteristics were studied for a cylindrical tank theoretically and experimentally. As a result, it is confirmed that the reverded U-tube works as a dynamic damper to suppress the resonant amplitude of sloshing to less than 1/1O of the undamped amplitudes, when the ratio of the natural frequency of sloshing to that of liquid columns in the U-tube is set nearly equal to unity. When two U-tubes are set symmetrically in a cylindrical tank in a cross configuration they can suppress resonant sloshing against the excitations in any direction. The frequency response of the surface elevation calculated by the Boundary Element Method shows a good agreement with those obtained by the experiments.
