ANTIMOTION DEVICE USING SWIRLING FLOW AND ANTIMOTION METHOD USING SWIRLING FLOW

摘要

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
