Flexible design method for segmented connection of surface ship

Abstract

The invention relates to a flexible design method for segmented connection of a surface ship, which comprises the following steps of: forming a block subsection division scheme in a technical design stage of overall design; in the construction design stage of the overall design, structural detailed design is conducted on segments according to a technical design block segment division scheme; according to the overall design, the dislocation principle knowledge of plates and aggregates is marked in a three-dimensional mode at the segmented connecting positions of the structural segmented three-dimensional model; according to the overall design, a segmental structure design scheme and general principle knowledge of segmental dislocation connection are transferred to the downstream along with the model at the same time; and after receiving the knowledge of the segmental structure design scheme and the segmental dislocation connection principle, the assembly factory arranges and designs segmental dislocation connection nodes according to the actual situation of the factory to form a segmented connection dislocation scheme of the production design structure. According to the method, the water surface ship is connected in sections and flexibly designed, the requirement of the overall design for the structural performance can be met, and the method can adapt to changes caused by actual construction factors of an assembly factory site.

Description

technical field [0001] The invention belongs to the technical field of structural design of surface warships, and in particular relates to a flexible design method for section connection of surface warships. Background technique [0002] In order to improve shipbuilding efficiency, regional construction and segmented shipbuilding have been gradually implemented in major domestic shipyards in my country. In the segmented shipbuilding mode, the general specification for ships GJB4000-2000 clearly requires that surface ships "at the segmental joints of the general segment, the longitudinal frame butt joints of the outer plate and deck and the butt joints of the plates should generally be staggered by 200mm" . The segmental connection design includes the location of the segmental joints and the length and direction of the staggered reinforcement, and the staggered direction of the reinforcement is closely related to the loading and closing sequence of the segments. For the pre...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the above-mentioned prior art, under the "one factory and multiple factories" subsection shipbuilding mode, the subsection construction sequence of surface warships is different due to different shipyard construction methods, material arrival sequence, outfitting sequence, etc. The reason is that the overall design institute cannot determine a unified and fixed segmental dislocation connection scheme, and provides a flexible design method for segmental connection of surface ships under the "one factory and multiple factories" segmental shipbuilding mode. This method can not only The requirements for segmental connection in the overall design can be guaranteed, and the requirements of different construction sequences of multiple assembly plants can be met, the workload of collaborative design is reduced, and the efficiency of ship development is improved. At the same time, the method combines the knowledge of segmental connection design constraints with the The 3D model is transmitted to the downstream at the same time, breaking the previous working mode of "modeling by the overall design, overturning by the assembly plant, and a large number of coordination and confirmation by the factory", and providing a solution for the new development mode of MBSE ships
