Problems solved by technology

[0003] At present, major shipyards generally have computer-aided hull construction systems. After completing the lofting of the theoretical hull shape and the generation of rib shape lines, the hull structure modeling is carried out, and the hull structure parts are expanded to enter the plate and profile database. The bilge keel is a complex hyperbolic plate. The unfolded parts cannot be directly used for nesting, cutting and installation construction. Therefore, manual lofting is required. The traditional manual lofting process is complicated, with large errors and low precision, and is prone to mistakes. put up

Embodiment Construction

[0020] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "top", "bottom" etc. Orientation or positional relationship is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention.

[0022] The bilge keel is a continuous profile installed on the ship's bilge (that is, the linear part connect...

Abstract

The invention relates to the technical field of hull construction, A method for unfolding a bilge keel is disclosed, the bilge keel is divided along the hull length according to the rib spacing by three-dimensional modeling method, converting the bilge keel between two adjacent ribs into a quadrilateral bilge keel area, The diagonal line connecting the quadrilateral turns the bilge keel area intotwo triangular areas, and measures the side length of the triangle on the model diagram, which can reflect the line shape of the bilge keel intuitively and clearly through the method of constructing the model diagram. At the same time, the development diagram obtained by directly measuring the real length on the model diagram is more accurate and efficient.

Description

technical field [0001] The invention relates to the technical field of hull construction, in particular to a method for deploying a single-board bilge keel. Background technique [0002] The bilge keel is generally used on ships with a small square coefficient to reduce roll and pitch and increase seakeeping and stability. The setting of the bilge keel is mainly to increase the damping of the ship’s roll and reduce the degree of roll. A fixed anti-rolling device. Generally arranged symmetrically on both sides of the ship, there are two types of single-plate bilge keel and triangular bilge keel. [0003] At present, major shipyards generally have computer-aided hull construction systems. After completing the lofting of the theoretical hull shape and the generation of rib shape lines, the hull structure modeling is carried out, and the hull structure parts are expanded to enter the plate and profile database. The bilge keel is a complex hyperbolic plate. The unfolded parts c...
