In the process of developing ship building in China, part of links are digitalized, but the integrated flow of digitalized design and building is not opened. At present, the design data of two units of a general assembly plant and a final assembly plant cannot be directly transmitted and inherited, upstream three-dimensional CAD data cannot be fully utilized, inconsistency with product design data caused by process design conversion cannot be completely eliminated, and inheritance, normalization, standardization and optimization of process design are difficult to realize. In the traditional two-dimensional process design, a process designer abstracts a three-dimensional space and a welding sequence in the mind and finally expresses the three-dimensional space and the welding sequence in a plane (two-dimensional) mode, and three-dimensional and two-dimensional conversion between design and construction wastes time and labor and is low in efficiency. Because the traditional process design takes two-dimensional expression as a main mode, the process design change and optimization period is long, the change of a model and the quick processing of the design change are not facilitated, the quality of a scheme depends on personal experience, qualitative and quantitative analysis means are lacked, the process design level is caused to vary from person to person, and the construction period and the construction cost are increased. The two-dimensional process design environment does not have the three-dimensional process verification capability, so that a series of problems such as whether interference exists in assembly, whether the assembly sequence is reasonable, whether tooling equipment meets requirements, whether an operation space is open and the like can be exposed in the construction stage. Any problem in any link can affect the development progress and quality.
Therefore, the great innovation in the development mode, the improvement of the design quality, the improvement of the design mode and the realization of the technical progress are urgently required. The ship body is used as the basic part of the ship, the sections of the ship body are intermediate products for forming the ship body, the ship body is reasonably divided into a plurality of structural sections for forming independent assembly units according to the structural characteristics of the ship body, the production conditions of a shipyard and the requirements of a construction process, the structural sections are formed by a series of plates and frameworks, and compared with other welding structures, the ship body has the characteristics of more parts and complex structure.
Therefore, the application provides a process collaborative simulation method, which is applied to a hull segmentation process, and solves the problems that the design requirement of a collaborative process cannot be met, the process design efficiency is low, a scientific process design optimization means is lacked, and the three-dimensional process design verification cannot be carried out, so that the goal of collaborative simulation can be achieved, and the process efficiency is improved.
The ship body is an essential part of the ship and can be divided into a main body part and an upper building part. The main body part is generally the part below the upper deck, which is a hollow body with a specific shape enclosed by the hull (bottom and side) and the upper deck, and is the key part for ensuring the required buoyancy, navigation performance and hull strength of the ship. The hull is typically used for deploying power plants, loading cargo, storing fuel and fresh water, and deploying other various compartments.
The ship body segmentation process is that a ship body built in a shipyard is divided into a plurality of segments according to the structural characteristics of the ship body, the production conditions of the shipyard, the ship body building process and the like, the segments are manufactured respectively firstly, small segments are assembled into large segments or total segments, and finally the large segments or the total segments are folded into a complete ship body in sequence. According to the structural characteristics of the ship body, the production conditions of a shipyard and the requirements of a construction process, the ship body is reasonably divided into a plurality of ship body structural sections which form independent assembly units. The device can be divided into a plane section, a curved section, a three-dimensional section and the like according to the appearance; the device can be divided into a deck section, a side section, a bulkhead section, a bottom section, a head-tail section and the like according to parts. Because the plane segmentation is simpler, some factories establish a plane segmentation production line so as to improve the production efficiency. The curved surface segmentation is more complicated, usually build on the bed-jig, but can make most electric welding go on under the state of overhead welding through turning over in segmentation, improve assembly, welded quality and efficiency. In order to meet the requirements of the pre-outfitting process, after the structure of the section is finished, various devices, pipelines, cables, outfitting and the like in the section can be installed in advance to form a more complete assembly unit, and then the assembly unit is sent to be assembled on a shipway to shorten the shipbuilding period. In general, the division of the hull sections is greatly related to the production technical conditions and process options of the shipyard
