【摘要】：隨著全世界的經(jīng)濟(jì)的不斷發(fā)展，對能源的需求量也與日俱增，，人們對于能源的需求逐漸從陸地轉(zhuǎn)到海洋，以此來解決自身的能源危機(jī)。海上石油鉆井平臺、海上大型發(fā)電設(shè)備等各種海工設(shè)備越來越受到重視。在海上大型圓筒的對位安裝過程中，由于圓筒重量重、所需的空間大、自身結(jié)構(gòu)復(fù)雜以及海浪顛簸起伏等一系列條件，使得大型圓筒的安裝遇到一定的難題。因此有必要設(shè)計一套合適的海上大型圓筒對位安裝液壓與電氣控制系統(tǒng)。本文基于機(jī)械設(shè)計、液壓系統(tǒng)及計算機(jī)工業(yè)控制理論，借鑒國內(nèi)外相關(guān)工程經(jīng)驗(yàn)，對自動對位安裝系統(tǒng)進(jìn)行了相關(guān)探討。 本文針對海上大型圓筒安裝自動對位系統(tǒng)，主要做了以下研究： (1)對多缸同步液壓系統(tǒng)進(jìn)行分析并進(jìn)行適當(dāng)?shù)暮喕�，利用AMESim軟件搭建了六缸同步液壓系統(tǒng)模型，并對其進(jìn)行了仿真分析，得到了六缸位移同步曲線及液壓系統(tǒng)中的壓力波動等特性曲線。 (2)設(shè)計自動對中機(jī)械方案、液壓系統(tǒng)及電氣監(jiān)控系統(tǒng)。利用Visual Basic6.0軟件搭建了自動對中的開發(fā)平臺，根據(jù)精定位階段的控制算法，編寫相關(guān)的程序。本課題綜合已有技術(shù)和經(jīng)驗(yàn)，借鑒國外相關(guān)項目資料，提出精定位自動對中系統(tǒng)的激光檢測方案及控制算法，使對接的法蘭螺栓孔對中。 （3）分析整體控制系統(tǒng)的總體控制需求，建立以PLC為控制核心，觸摸屏及工控機(jī)作為監(jiān)控單元的管控一體化的海上大型圓筒對位安裝的監(jiān)控系統(tǒng)。 通過以上內(nèi)容的研究，得出了一些重要結(jié)論，為以后大型圓筒法蘭對中提供一種新的方法和思路。最后，對進(jìn)一步工作的方向進(jìn)行了簡要的討論。
[Abstract]:With the continuous development of the world economy, the demand for energy is also increasing. The demand for energy is gradually transferred from land to sea, in order to solve their own energy crisis. Offshore oil drilling platforms, offshore large-scale power generation equipment and other marine equipment has been paid more and more attention. During the installation of large cylinders on the sea, due to their heavy weight, large space, complicated structure and ups and downs of waves, the installation of large cylinders has encountered some difficulties. Therefore, it is necessary to design a suitable hydraulic and electrical control system. Based on the theory of mechanical design, hydraulic system and computer industry control, and referring to the relevant engineering experience at home and abroad, this paper discusses the automatic alignment installation system. In this paper, the main research work is as follows: (1) the multi-cylinder synchronous hydraulic system is analyzed and simplified, and a six-cylinder synchronous hydraulic system model is built by using AMESim software. The characteristic curves of displacement synchronization of six cylinders and pressure fluctuation in hydraulic system are obtained. (2) automatic alignment mechanical scheme, hydraulic system and electrical monitoring system are designed. The development platform of automatic alignment is built by using Visual Basic6.0 software. According to the control algorithm of precise positioning stage, the relevant programs are written. This subject synthesizes the existing technology and the experience, draws lessons from the foreign related item data, proposes the precision localization automatic alignment system laser detection plan and the control algorithm, Make the butt flange bolt hole alignment. (3) analyze the overall control requirements of the overall control system, establish the PLC as the control core, Touch screen and industrial control computer as the monitoring unit of the integrated monitoring system for the installation of large-scale cylinders on the sea. Through the above research, some important conclusions are obtained, which provide a new method and train of thought for the large cylinder flange alignment in the future. Finally, the direction of further work is briefly discussed.
