【摘要】：FPSO尾輸油過程中軟管絞車需要完成收放軟管的這一動(dòng)作過程,為了有效利用發(fā)動(dòng)機(jī)輸出功率及提高絞車工作性能,其液壓系統(tǒng)廣泛采用恒功率控制變量機(jī)構(gòu)。而變量機(jī)構(gòu)的控制特性是關(guān)系整個(gè)液壓系統(tǒng)品質(zhì)的重要標(biāo)準(zhǔn),為了對(duì)恒功率控制進(jìn)行優(yōu)化,就需要分析變量機(jī)構(gòu)的靜動(dòng)態(tài)特性及部件參數(shù)對(duì)其特性的影響。 通過分析軟管絞車的工作原理及工況特點(diǎn),建立合理的系統(tǒng)數(shù)學(xué)模型,并利用仿真軟件AMESim對(duì)其進(jìn)行動(dòng)態(tài)仿真,可以直觀地研究恒功率變量機(jī)構(gòu)的特性。該方法可以在液壓元件及系統(tǒng)的開發(fā)設(shè)計(jì)中對(duì)設(shè)計(jì)者具有一定的指導(dǎo)意義,縮短研發(fā)周期,并且能夠節(jié)省一定的人力、物力和財(cái)力。 本文以工程機(jī)械中軟管絞車的液壓系統(tǒng)為研究對(duì)象,側(cè)重分析系統(tǒng)中變量泵的恒功率控制機(jī)構(gòu)。第一部分,介紹了尾輸油系統(tǒng)的工作原理、分析了軟管絞車的工作原理以及恒功率控制方式的特性；第二部分,在對(duì)恒功率控制機(jī)構(gòu)進(jìn)行合理線性化之后,建立了系統(tǒng)的數(shù)學(xué)模型,重點(diǎn)分析和建立的是變量泵的恒功率控制機(jī)構(gòu)的數(shù)學(xué)模型；第三部分,也是本文的重點(diǎn)所在,利用仿真軟件AMESim搭建了系統(tǒng)的仿真框圖,設(shè)置好相應(yīng)的參數(shù)后,對(duì)其仿真結(jié)果進(jìn)行分析,得出系統(tǒng)的響應(yīng)特性,改變變量機(jī)構(gòu)的主要部件參數(shù),然后再進(jìn)行仿真計(jì)算,分析主要部件參數(shù)對(duì)動(dòng)態(tài)響應(yīng)特性的影響。最后提出優(yōu)化恒功率控制變量機(jī)構(gòu)的方案,改變彈簧參數(shù)及增加彈簧的數(shù)量至三根甚至四根,以期達(dá)到更加完美的恒功率控制。 本文通過以上幾個(gè)方面的分析,得出了恒功率控制變量機(jī)構(gòu)主要部件參數(shù)對(duì)恒功率特性的影響規(guī)律,研究了變量機(jī)構(gòu)設(shè)計(jì)的改進(jìn)理念,對(duì)液壓系統(tǒng)恒功率控制的開發(fā)和設(shè)計(jì)起到一定的參考作用。
[Abstract]:In order to effectively utilize the engine output power and improve the working performance of the winch, the hose winch needs to complete the process of retracting and releasing the hose in the process of FPSO tail oil transportation. The constant power control variable mechanism is widely used in its hydraulic system, and the control characteristics of the variable mechanism is an important standard related to the quality of the whole hydraulic system, in order to optimize the constant power control. It is necessary to analyze the static and dynamic characteristics of the variable mechanism and the influence of component parameters on its characteristics. By analyzing the working principle and working condition characteristics of the hose winch, a reasonable mathematical model of the system is established, and the dynamic simulation is carried out by using the simulation software AMESim. This method can be used in the development and design of hydraulic components and systems, which has a certain guiding significance for designers, shortens the research and development cycle, and can save a certain amount of manpower. Material and financial resources In this paper, the hydraulic system of the hose winch in construction machinery is taken as the research object, and the constant power control mechanism of the variable pump in the system is emphatically analyzed. The first part introduces the working principle of the tail oil transportation system. The principle of hose winch and the characteristics of constant power control mode are analyzed. In the second part, after the constant power control mechanism is linearized reasonably, the mathematical model of the system is established, and the mathematical model of the constant power control mechanism of the variable pump is analyzed and built. The third part is also the focus of this paper, using the simulation software AMESim to build the system simulation block diagram, after setting up the corresponding parameters, the simulation results are analyzed, and the response characteristics of the system are obtained. The main component parameters of the variable mechanism are changed and then simulated. The influence of the main component parameters on the dynamic response characteristics is analyzed. Finally, the scheme of optimizing the variable mechanism with constant power control is put forward. Change the spring parameters and increase the number of springs to three or even four in order to achieve a more perfect constant power control. Through the analysis of the above several aspects, the influence law of the main component parameters of the constant power control variable mechanism on the constant power characteristic is obtained, and the improved concept of the variable mechanism design is studied. It plays a certain reference role in the development and design of constant power control of hydraulic system.
