To provide an antimotion device using swirling flow capable of actively controlling an antimotion effect imparted to structures such as a vessel or a floating body and in addition capable of reducing swinging motion in a wide frequency range without being dependent on a specific frequency of the structure and an antimotion method using the swirling flow.SOLUTION: An antimotion device includes: liquid storage means 10 in an annular shape in a plan view mounted on a structure 2 for storing liquid 20 with space X remaining above the liquid 20; swirling flow generation means 30 for generating a swirling flow in the liquid 20; and swirling flow control means 40 for controlling the swirling flow generation means 30 and the swirling flow is controlled.SELECTED DRAWING: Figure 2
【課題】船舶や浮体等といった構造物に及ぼす減揺効果を能動的に制御可能とし、また、構造物の固有振動数に依存せず幅広い周波数域での減揺を可能とする、旋回流を利用した減揺装置、及び旋回流を利用した減揺方法を提供すること。【解決手段】構造物2に搭載されて液体20を液体20よりも上方に空間Xを残して収納する平面視した形状が円環状の液体収納手段10と、液体20に旋回流を発生させる旋回流発生手段30と、旋回流発生手段30を制御する旋回流制御手段40とを備え、旋回流を制御する。【選択図】図2
