摘 要
近年來,中國造船業(yè)有很大的進步,但與日韓等造船強國相比,造船技術(shù)水平卻有著明顯的差距,主要體現(xiàn)在精度管理方面。精度管理水平的高低直接影響船舶的建造質(zhì)量以及船廠的經(jīng)濟效益。因此,中國要想成為造船強國,跟上時代發(fā)展的步伐,就必須在船舶建造中推行精度管理體系,以此來保證船舶的建造質(zhì)量,提高生產(chǎn)效率。
本文在廣泛調(diào)研的基礎(chǔ)上,根據(jù)一般管理體系的特點,建立了符合船體分道建造要求的精度管理體系;闡述了精度計劃的內(nèi)容;結(jié)合船體分道建造的特點,分析了不同制造級的精度控制程序,實現(xiàn)了全船的精度管理;采用數(shù)理統(tǒng)計的方法對精度控制階段的反饋數(shù)據(jù)進行分析,建立了精度控制反饋數(shù)據(jù)庫。主要研究內(nèi)容與成果包括:
(1) 根據(jù)船體分道建造的特點,在闡述了管理體系的概念和組成的基礎(chǔ)上,建立了符合船體分道建造要求的精度管理體系。
(2) 詳細闡述了精度計劃的內(nèi)容、作用及編制要求,介紹了尺寸鏈理論,并羅列了系統(tǒng)補償量的分配方式和理論計算公式;分析了加放補償量流程和尺寸精度補償?shù)脑瓌t;最后歸納了船體建造的精度標準和對船體建造精度管理水平進行評價的原則。這些都是整個精度管理體系的基礎(chǔ)。
(3) 結(jié)合船體分道建造的特點,從典型工藝流程、精度控制點、精度標準與檢驗三個方面出發(fā),詳細闡述了船體分道建造中零件加工和裝配、部件裝配、組件裝配、分段裝配、總段裝配和船臺(塢)合攏七個制造級的精度控制程序。
(4) 建立了船體分道建造反饋數(shù)據(jù)庫,分析了數(shù)據(jù)庫的基本結(jié)構(gòu)和數(shù)據(jù)庫主要的數(shù)據(jù)文件,對數(shù)據(jù)庫的建立進行了相應(yīng)的需求分析、概念設(shè)計分析,最后以一個分段為例,驗證了該反饋數(shù)據(jù)庫的可行性,為統(tǒng)計分析生產(chǎn)實際的加工數(shù)據(jù)指導(dǎo)后道工序提供了技術(shù)支持和保障。
論文的研究成果對國內(nèi)一些船廠精度管理體系的建立有一定的指導(dǎo)意義,對提高船體建造質(zhì)量,縮短建造周期有一定的積極意義。

Abstract
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, eva luated 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.

Keywords: hull process lane construction; compensatory value; accuracy management system; database
