ANTI-ROLL DEVICE, AND VESSEL

An anti-roll device (10) comprises: a base (20) fixed to an object (1) to be reduced in rolling; a gimbal (40) which is supported so as to be rotatable about a first shaft (RA); a damper mechanism (30) which dampens the relative rotative movement of the gimbal (40) with respect to the base (20); and...

Beschreibung
Zusammenfassung:	An anti-roll device (10) comprises: a base (20) fixed to an object (1) to be reduced in rolling; a gimbal (40) which is supported so as to be rotatable about a first shaft (RA); a damper mechanism (30) which dampens the relative rotative movement of the gimbal (40) with respect to the base (20); and a flywheel (50) which is rotatable about a second shaft (RB) perpendicular to the first shaft (RA). The damper mechanism (30) is a passive damper mechanism. A first value (D1) of a damping coefficient (D) of the damper mechanism (30) when the angular velocity of the gimbal (40) is a first angular velocity is greater than a second value (D2) of the damping coefficient (D) of the damper mechanism (30) when the angular velocity of the gimbal (40) is a second angular velocity lower than the first angular velocity.
