Abstract

The invention provides a variable-width bilge keel and a ship, and relates to the technical field of ship equipment. The variable-width bilge keel provided by the invention comprises a keel plate. Thekeel plate includes a first contour edge and a second contour edge, the first contour edge being for fitting with a side of the hull and extending along a length direction of the hull; The second contour edge is opposite to the first contour edge; The distance between the first contour edge and the second contour edge in the normal direction of the first contour edge gradually increases from themiddle to both ends of the first contour edge. The bilge keel provided by the invention is installed on the side of the ship, and the first contour edge is in contact with the side of the ship. The bilge keel with variable width provided by the invention alleviates the technical problem that the bilge keel existing in the prior art has the effect of reducing the ship sway and is not conducive to fully improving the sea keeping performance of the ship.

Description

technical field [0001] The invention relates to the technical field of ship equipment, in particular to a variable-width bilge keel and a ship. Background technique [0002] When a ship is sailing, waves will cause the ship to sway. The swaying movement of the ship during navigation will have adverse effects on the crew, hull structure and mechanical equipment. The swaying motion of a ship includes six forms: roll, pitch, yaw, surge, sway, and heave; among them, the roll has a greater impact on the seakeeping of the ship. The seakeeping research of ships is an important and complex subject in the shipbuilding industry. Seakeeping is one of the important performances of ships, the basic guarantee for safe navigation of ships, and one of the main contents of ship inspections. It is an important subject to improve the seakeeping of ships to study the measures and devices to slow down the rolling motion of ships. [0003] In the prior art, in order to slow down or reduce the ...
