Abstract/Summary:
In recent years, Chinese shipbuilding industry has made great progress. However, compared with the shipbuilding powers such as Japan and South Korea, the gap is narrowing, and this gap is mainly reflected in the accuracy management. The level of accuracy management directly affects the quality of the construction of the ship, as well as the economic benefits of the shipyard. As a result, if Chinese shipbuilding industry want to become the first shipbuilding power in the world and keep up with the pace of development of the times, it is necessary to implement the accuracy management in the shipbuilding to ensure the quality of the construction of the ship and promote productivity.Based on the analysis of the concept and composition of management system, this thesis established the accuracy management based on the hull process lane construction; elaborated the contents of accuracy plan in detail; combined with the features of hull process lane construction, elaborated the accuracy control processes in every stage of hull process lane construction ; established a database. The main contents and results of this thesis include:1. According to the characters of hull process lane construction, this article first explained concept and composition of management system, and then builded an accuracy management system based on this theory.2. Elaborated the contents, roles and demands of accuracy plan in detail first, this article introduced the theory of dimension chain, list the distribution of compensation, set up the theoretical formulas about compensatory value. Next this article analyzed the process of placing compensation and the principle of compensation for dimensional accuracy. At last, this article summarized accuracy standards for hull construction, evaluated the management of hull accuracy construction. All these are base of the accuracy management system.3. Combined with the features of hull process lane construction, this article elaborated the accuracy control processes in every stage of hull process lane construction such as parts machining and assembly, parts assembly, component assembly, subassembly, general assembly in paragraph and berth close from typical process, accuracy control points and accuracy standards and testing three respects.4. Established a database, analyzed the basic structure and the main data file of this database. Made demand analysis and concept design analysis for the establishment of this database. At last, this article showed the screens of information entry and processing, which provided technical support and security for the statistics and analyze of actual production data and instruct last procedure. The research results of this thesis have some guidance on the building of accuracy management system for some shipyards and have some positive significance on improving the quality of hull construction and shortening the construction cycle.
