【摘要】：船用起重機主要用于船舶吊運重物,備料等。但船用起重機的工作狀況較為復雜,為了使船用起重機工作更加平穩(wěn),起升重物更加準確穩(wěn)定,本文的主要工作在于為船用起重機吊盤式防搖系統(tǒng)設(shè)計液壓驅(qū)動系統(tǒng)。相較于之前的機械控制系統(tǒng),液壓系統(tǒng)具有布局靈活方便,系統(tǒng)結(jié)構(gòu)簡單,同等功率下質(zhì)量輕,工作平穩(wěn),便于操作等優(yōu)點。但目前,在船用起重機防搖裝置上使用液壓系統(tǒng)的情況不多,因此本文設(shè)計的恒張力液壓系統(tǒng)仍然具有較為重要的意義。本文依托實驗室項目,將航標船起重機作為主要研究對象,進行液壓系統(tǒng)的設(shè)計和仿真分析,本文的主要研究內(nèi)容如下:第一,調(diào)研、收集船用起重機以及恒張力液壓系統(tǒng)的相關(guān)設(shè)計信息,了解國內(nèi)外船起重起重機以及恒張力液壓系統(tǒng)的發(fā)展現(xiàn)狀,根據(jù)船用起重機的特點和防搖的具體要求提出整體設(shè)計方案;第二,根據(jù)吊盤式防搖系統(tǒng)的實際工況,對吊盤式防搖系統(tǒng)進行靜力學分析。設(shè)計恒張力液壓控制系統(tǒng)方案,根據(jù)要求選擇既滿足要求又合理的恒張力液壓控制系統(tǒng)。第三,根據(jù)系統(tǒng)所需提供的負載要求計算出液壓控制系統(tǒng)主要元件的技術(shù)參數(shù),從而對系統(tǒng)所需的液壓元件進行選型。第四,根據(jù)前面設(shè)計的液壓控制系統(tǒng),建立恒張力控制系統(tǒng)的數(shù)學模型,分析防搖系統(tǒng)的動態(tài)特性,從而得到影響張力的各個因素。第五,用AMESim軟件對吊盤式防搖液壓系統(tǒng)進行仿真分析,得到液壓系統(tǒng)控制吊盤式防搖的變化曲線圖,從而分析船用起重機吊盤式防搖液壓系統(tǒng)的操縱性。
[Abstract]:Marine crane is mainly used for lifting heavy goods, materials, etc. But the working condition of the marine crane is more complicated. In order to make the crane more stable and the lifting weight more accurate and stable, the main work of this paper is to design the hydraulic drive system for the anti-rocking system of the marine crane. Compared with the previous mechanical control system, the hydraulic system has the advantages of flexible layout, simple system structure, light weight under the same power, stable work, easy operation and so on. But at present, the use of hydraulic system on the anti-rocking device of marine crane is rare, so the constant tension hydraulic system designed in this paper is still of great significance. Based on the laboratory project, this paper takes the navigation ship crane as the main research object, carries on the hydraulic system design and the simulation analysis, the main research content of this paper is as follows: first, the investigation, Collect the relevant design information of marine crane and constant tension hydraulic system, understand the development status of ship crane and constant tension hydraulic system at home and abroad, and put forward the overall design scheme according to the characteristics of marine crane and the specific requirements of anti-rolling; Secondly, according to the actual working conditions of the anti-rolling system, the static analysis of the anti-rolling system is carried out. A constant tension hydraulic control system is designed. According to the requirement, a constant tension hydraulic control system is selected. Thirdly, the technical parameters of the main components of the hydraulic control system are calculated according to the load requirements of the system, and the hydraulic components required by the system are selected. Fourthly, according to the hydraulic control system designed before, the mathematical model of the constant tension control system is established, and the dynamic characteristics of the anti-rolling system are analyzed, and the factors influencing the tension are obtained. Fifthly, using AMESim software to simulate and analyze the anti-rolling hydraulic system of hoist type, get the change curve of anti-rolling of hoisting plate type of hydraulic system control, thus analyze the maneuverability of anti-rolling hydraulic system of hoisting plate type of marine crane.
