Title:
ANTIMOTION DEVICE AND SHIP
Document Type and Number:
Japanese Patent JP2017019315
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antimotion device comprising a passive type damper which can preferably attenuate vibration even when vibration angular speed of a vibration attenuation object is small.SOLUTION: An antimotion device comprises: a base 20 which is fixed to a vibration attenuation object; a gimbal 40 which is supported rotatably around a first axis RA; a damper mechanism 30 which attenuates relative rotation motion of the gimbal 40 to the base 20; and a fly wheel 50 which can rotatable around a second axis RB vertical to the first axis RA. The damper mechanism 30 is a passive type damper mechanism. A first value of a damping coefficient of the damper mechanism 30 when angular speed of the gimbal 40 is first angular speed is larger than a second value of a damping coefficient of the damper mechanism 30 when the angular speed of the gimbal 40 is second angular speed which is smaller than the first angular speed.SELECTED DRAWING: Figure 3
