Problems solved by technology

[0003] During ship construction, because the welding is carried out in sections one by one, if the structural deformation during the assembling process of the sections cannot be monitored in time, it will easily lead to large assembly errors in the hull structure and affect the construction accuracy of the ship; in addition, in the construction process , the greater the construction deformation of the ship, the greater the welding residual stress accumulated in the segmental welds, which will easily lead to damage to the hull structure after the ship is in operation

Abstract

The invention discloses a method for monitoring structural deformation in a ship construction process. A bottom section located at the bottom of a ship is provided, multiple monitoring devices for monitoring deformation are installed before the bottom section is assembled with other sections of the ship, and the monitoring devices are distributed at the bottom of the bottom section according to adesign line of the ship. By installing the monitoring devices before the bottom section of the ship is assembled with other sections of the ship, deformation conditions of the bottom section in the assembly process can be monitored in time so that measures can be taken in time to prevent continuously aggravated deformation, the construction accuracy of the ship is improved, welding residual stressis reduced, and the safety of the ship after operation is ensured.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for monitoring structural deformation during ship construction. Background technique [0002] As the size of the ship increases, it is generally chosen to build the ship in the dock. When building a ship in a dock, the pier is generally arranged first, and then the built sections are transported to the dock by a gantry crane for welding and assembly. When assembling sections, unless the hull structure is obviously deformed, the total station will be used to measure the deformed parts. In addition, generally only attention is paid to the deformation of the ship's length direction in the process of ship construction, and little attention is paid to the deformation of the ship's width direction. [0003] During ship construction, because the welding is carried out in sections one by one, if the structural deformation during the assembling process of the sections cannot be m...
