【摘要】：造船精度控制管理在船舶建造过程中扮演着重要角色,直接影响船舶的安全性能及使用性能,这意味着我们在船体分段制作阶段、船体分段的总组阶段及合拢过程中都必须严格控制整体精度,以满足新时代船舶建造的精度要求。中、日、韩均属于当今世界的造船强国,然中国在造船精度控制上依然存在不少劣势。具体而言,除了在船体分段制作精度控制技术方面,在船体分段总组与合拢精度控制方法上也存在较大差距。本文的研究重点即是对船体建造中的总组与合拢过程进行精度控制与管理,使该过程中的精度管理水平得到改善,然后,将精度控制管理方法应用于实船建造中,对指标数据进行统计分析,结果验证了精度控制管理方法的有效性。本文以Ecosystem为工具,以提高船体建造精度管理水平为目标,以大连船舶重工集团有限公司为达飞所建造的C9200系列集装箱船为研究对象,在船体建造流程及工艺技术等相关理论的基础上,提出了船体分段总组与合拢精度问题的应对措施,建立了精度控制指标,指出以往用补偿量代替余量的方式进行精度管理控制的不足,然后再借助计算机技术,建立了基于Ecosystem的船体分段总组与合拢精度控制管理模型。之后针对C9200首制船船体分段在总组及合拢过程中出现的一次定位成功率较低,平台总组及船坞合拢切修率高等问题,应用建立的精度控制管理模型,在后续船上对船体建造精度进行改善,取得了很好的效果。总之,本文结合现代计算机技术对船体建造精度进行控制管理,为实现数字化造船,提高船体建造水平和效率提供了方法依据。基于Ecosystem的精度控制模型的成功建立及应用,不仅很好地解决了分段总组与合拢切修率高的精度问题,也有效提高了船体总组合拢效率,节省大量人力物力,缩短船舶建造周期,实现船厂的经济利益最大化,从而真正意义上达到日韩先进造船水平。
[Abstract]:The management of shipbuilding precision control plays an important role in the process of ship construction, which directly affects the safety performance and service performance of the ship, which means that we are in the stage of making the hull segment.In order to meet the requirements of ship construction in the new era, it is necessary to strictly control the overall accuracy in the general assembly stage and the closing process of the hull segment.China, Japan and South Korea all belong to the shipbuilding power in the world, but China still has many disadvantages in shipbuilding precision control.In particular, in addition to the control technology of hull segment manufacturing precision, there is also a big gap between the hull segment assembly and the closing precision control method.The research emphasis of this paper is to control and manage the accuracy of the total group and closing process in the hull construction, so as to improve the precision management level in the process, and then apply the precision control management method to the actual ship construction.The statistical analysis of the index data shows that the precision control management method is effective.In this paper, Ecosystem is used as a tool to improve the management level of hull construction precision, and the C9200 series container ship built for Dafe by Dalian Shipbuilding heavy Industry Group Co., Ltd is taken as the research object.On the basis of the theory of hull construction process and technology, the paper puts forward the measures to deal with the problem of the accuracy of hull segment assembly and closure, and establishes the precision control index.This paper points out the shortcomings of precision management and control by using compensation instead of margin in the past, and then, with the help of computer technology, establishes the control model of hull segment assembly and closure accuracy based on Ecosystem.After that, aiming at the problems of low success rate of primary positioning in the process of general assembly and closure of C9200 ship hull segment, and high rate of closure and repair of platform group and dock, the established precision control management model is applied.The accuracy of ship hull construction is improved and good results are obtained.In a word, this paper combines the modern computer technology to control and manage the hull construction precision, which provides the method basis for realizing digital shipbuilding and improving the level and efficiency of hull construction.The successful establishment and application of the precision control model based on Ecosystem not only solves the accuracy problem of high cutting and repairing rate of segment assembly and closure, but also effectively improves the efficiency of hull assembly, saves a lot of manpower and material resources, and shortens the construction period of ships.To maximize the economic benefits of shipyards, so as to reach the level of advanced shipbuilding in Japan and South Korea.
