【摘要】：現(xiàn)今,國內(nèi)先進船廠開始推行造船精度管理，但它所提及的精度管理還都局限在船體領域，而在造船生產(chǎn)過程中，常常會出現(xiàn)舾裝件施工與船體建造之間的矛盾。造船精度管理應該是全方位和系統(tǒng)的，在考慮船體精度管理的同時也要兼顧舾裝精度的匹配，舾裝精度管理勢在必行。 根據(jù)現(xiàn)行船體精度管理體系，結合國外先進船廠舾裝精度管理模式，本文針對船舶舾裝中最重要的管舾裝進行精度控制研究。與船體建造類似，管舾裝生產(chǎn)流水線也從加工制作開始，以彎管回彈現(xiàn)象為研究背景，理論分析彎管回彈的原理，通過一定的試驗驗證，總結出回彈規(guī)律，對管子制作本身的精度進行彈性控制。從管子單件制作到單元組管線的安裝定位都需要精度控制標準，依托國外先進船廠的管理經(jīng)驗和控制基準及大量的實例驗證，歸納出適用于我國造船生產(chǎn)模式的管舾裝精度控制基準書，設計并優(yōu)化舾裝精度測量檢查表，構建一個較為完整的船廠精度管理體系。實施管舾裝精度控制的難點在于安裝過程，以一艘油輪的雙層底分段為研究實例，根據(jù)設計的舾裝精度測量檢查表實地對分段上的管線安裝位置進行定位監(jiān)控，分析研究管線與船體分段的匹配現(xiàn)狀。海工裝備在建造時對精度的要求比民用船舶更加嚴格，以一座自升式鉆井平臺的樁靴沖樁管開口進行的精度定位方法來說明精度控制的測量與應用。本文主要目的是通過對管舾裝精度控制研究來減少安裝時合攏管的使用、避免硬裝配帶來的安全隱患和達到管舾裝與船體精度管理的完美匹配，，然而在現(xiàn)階段合攏管的使用是必然的，管舾裝能否成功對接很大程度上取決于合攏管的制作精度，而“合攏管再現(xiàn)機系統(tǒng)”的成功應用使得合攏管制作精度大幅度提高，實現(xiàn)由人工制作向半自動、數(shù)字模擬制作轉換，減少耗材、勞動力和時間的消耗。 本文的創(chuàng)新點在于編制了管舾裝的制作和安裝精度基準，設計管舾裝的精度測量檢查表，結合船體精度測量表，形成一個較為全面的精度管理框架體系；應用MarineG2軟件模擬導出管線的實際制作安裝精度問題，對樁靴沖樁管開孔進行精度控制，指導現(xiàn)場一次性定位。
[Abstract]:Nowadays, advanced shipyards in China begin to carry out shipyard precision management, but the precision management mentioned by it is still limited to the hull field, and in the process of Shipbuilding production, there is often a contradiction between outfitting construction and hull construction. The accuracy management of Shipbuilding should be omni-directional and systematic. It is imperative to consider the matching of outfitting accuracy while considering hull precision management. According to the current hull accuracy management system and the foreign advanced shipyard outfitting accuracy management mode, this paper studies the accuracy control of the most important pipe outfitting in ship outfitting. Similar to the hull construction, the pipe outfitting production line also starts from the processing and manufacture. Taking the springback phenomenon of the curved pipe as the research background, the principle of the springback of the curved pipe is analyzed theoretically, and the springback law is summarized through certain experimental verification. Elastic control of the precision of pipe making itself. The precision control standard is needed from the manufacture of single pipe to the installation and positioning of unit group pipeline. Based on the management experience and control benchmark of foreign advanced shipyard and a large number of examples, The precision control datum of pipe outfitting suitable for shipyard production mode in China is summarized, the inspection table of outfitting accuracy measurement is designed and optimized, and a relatively complete shipyard accuracy management system is constructed. The difficulty of implementing pipe outfitting accuracy control lies in the installation process. Taking the double bottom section of an oil tanker as an example, the installation position of the pipeline on the segment is located and monitored according to the designed outfitting accuracy measurement and inspection table. The matching status of pipeline and hull segment is analyzed and studied. The precision requirement of marine equipment is more stringent than that of civil ships in the construction of marine equipment. The precision positioning method of pile shoe punching pile pipe opening of a Jack-up drilling platform is used to illustrate the measurement and application of precision control. The main purpose of this paper is to reduce the use of closed pipe during installation, avoid the hidden danger of safety caused by hard assembly and achieve the perfect matching between pipe outfitting and hull precision management by studying the precision control of pipe outfitting. However, at this stage, the use of closed pipe is inevitable. Whether the pipe outfitting can be successfully docked depends to a large extent on the making accuracy of closed pipe, and the successful application of "closed pipe reproducing machine system" greatly improves the precision of closed pipe making. Realize the conversion from manual production to semi-automatic, digital analog production, reduce the consumption of consumables, labor and time. The innovation of this paper is to compile the precision benchmark of pipe outfitting, to design the precision measurement and inspection table of pipe outfitting, and to form a more comprehensive precision management framework system combined with hull precision measurement scale. The accuracy of actual manufacture and installation of pipeline is simulated and derived by MarineG2 software, and the accuracy control of pile shoe punching pile pipe hole is carried out to guide the one-time positioning of the site.
