Abstract
The paper shows the urgency of creating a new methodological support for solving one of the urgent problems of optimizing the hull structure at the stages of its design and creation, which provides for finding a vector of optimized variables at which the efficiency criterion reaches an extreme value. F (x) → min (max) and the requirements for the structures of ships are fulfilled, specified by the corresponding restrictions ѱ, and determining the requirements of the technical specifications for the structures being created and their manufacturing technology. To solve the problem of optimizing the structure, a 3D-model of the structure and a 3D-model of assembly and welding equipment have been created. Taking into account the requirements of the technology to improve the accuracy of manufacturing the hull structures of ships and improve the quality of welded structures, as well as the requirements to reduce the stress-strain state in the created structures, the article makes proposals for the modernization of the universal rack-mount assembly and welding equipment and analyzes the stresses and strains arising in the structures, which has made it possible to assess feasibility of such modernization in order to increase accuracy and manufacturability of making hull structures and reduce their stress-strain state. Sketch and design models of this equipment have been built. Conclusions have been made based on the calculations results.
