A flywheel front cover and a flywheel rear cover are buckled to form a vacuum spherical shell, front-end electromagnetic poles are evenly distributed on the inner side of the flywheel front cover, rear-end electromagnetic poles are evenly distributed on the inner side of the flywheel rear cover, permanent magnet magnetic poles are evenly distributed on an outer hub of a flywheel, and permanent magnet magnetic poles are evenly distributed on an inner hub of the flywheel rear cover. When a ship jolts and shakes due to the influence of storm waves or ocean currents, the flywheel rotates at a high speed in the vacuum spherical shell in the left-right direction of the flywheel shaft, large rotational inertia is generated when the flywheel rotates at the high speed, and through energy transmission of the right side supporting damping cylinder, the left side supporting damping cylinder, the right side supporting damping cylinder rod and the left side supporting damping cylinder rod, the flywheel can rotate at the high speed. The energy for driving the vacuum spherical shell to swing left and right and horizontally is consumed, so that the rolling amplitude and frequency of the ship are greatly reduced, the course stability is improved, and the rolling amplitude and frequency of the ship can be reduced.
