船体分道建造的精度管理体系研究.docVIP

摘 要 近几年，中国造船业有了长足的进步，与日韩等造船强国相比，在年造船总量上的差距正在逐年缩小，并且有成为世界第一造船大国的趋势。但是在造船技术上却有着比较明显的差距，而这差距主要体现在精度管理方面。精度管理水平的高低，直接影响着船舶的建造质量以及船厂的经济效益。因此，中国造船要想成为世界第一造船强国，跟上时代发展的步伐，就必须在船舶建造中推行精度管理，保证船舶的建造质量，提高生产效率。 本文在分析了管理体系的概念和组成基础上，建立了基于船体分道建造的精度管理体系，然后详细分析了精度管理体系的各组成成分，并以浙江欧华造船有限公司1200TEU集装箱船的底部分段为基础验证了精度管理体系的可行性。主要研究内容与成果包括： 1.根据船体分道建造的特点，建立了相应的精度管理体系。 2.详细阐述了精度计划的内容、作用及编制要求，并罗列了相关补偿量的理论计算公式，这是整个精度管理体系的基础。 3.结合船体分道建造的特点，详细阐述了船体分道建造各阶段的精度控制程序，另外，精度控制的结果要满足船厂制定的精度标准，并列举了相关精度标准的例子作为参考。 4.设计了船体分道建造各阶段的精度控制反馈表的形式，这是精度管理体系不断完善的前提，是精度管理体系重要的组成。 5.以浙江欧华造船有限公司1200TEU集装箱船的底部分段为基础，验证了精度管理体系的可行性。 论文的研究成果对国内一些船厂精度管理体系的建立有一定的指导意义，对提高船体建造质量，缩短建造周期有一定的积极意义。 关键词：船体分道建造；补偿量；精度管理体系 Abstract In recent years, Chinese shipbuilding industry has made great progress, and the gap of years total shipbuilding output compared with the shipbuilding powers such as Japan and South Korea is narrowing, and will be the worlds largest shipbuilding country. But there is a more obvious gap in shipbuilding technology, 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 builded the accuracy management based on the hull process lane construction, and then detailedly analysed all components of the accuracy management system, and verified the feasibility of accuracy management system based on the bottom blocks of Zhejiang Ouhua Shipyard Co., Ltd.1200TEU container ships. The main contents and results of this thesis include: 1. According to the characters of hull process l
