【摘要】：抓斗式采礦船抓斗的動力提升系統(tǒng)載荷大、工況復(fù)雜，普通的傳動系統(tǒng)難于適應(yīng)其工作要求。為了實現(xiàn)對抓斗速度的有效控制，需借助液體粘性調(diào)速離合器的無級調(diào)速性能，組成能容可控的液力變矩器，以改善系統(tǒng)的經(jīng)濟性及動力性能。利用AMESim仿真平臺建立抓斗的動力提升系統(tǒng)模型，進行了抓斗的典型工況仿真，為抓斗船的液粘調(diào)速系統(tǒng)提供了一個很好的研究設(shè)計仿真平臺。論文主要包括： 首先，分析抓斗采礦船抓斗動力系統(tǒng)工作特性，，闡述液力變矩器應(yīng)用于抓斗提升系統(tǒng)的必要性。結(jié)合抓斗采礦船工作特點，分析液力變矩器與柴油機的共同工作的局限性。通過對液力變矩器的幾種調(diào)節(jié)方法的比較，確定在液力變矩器與柴油機之間串聯(lián)液體粘性調(diào)速離合器的解決方案。 其次，分析液粘調(diào)速離合器結(jié)構(gòu)組成及工作原理，利用AMESim仿真軟件，基于摩擦副、旋轉(zhuǎn)液壓缸、油膜承載的力學(xué)性能，建立了液粘調(diào)速離合器的閉環(huán)控制系統(tǒng)模型。 最后，分析液粘調(diào)速離合器對液力變矩器的調(diào)節(jié)原理，利用AMESim軟件建立液粘調(diào)速離合器控制液力變矩器的仿真模型，仿真驗證液粘調(diào)速離合器的調(diào)節(jié)效果。搭建采礦船抓斗提升系統(tǒng)的完整模型，通過仿真分析，驗證了液黏調(diào)速離合器的作用效果及模型的合理性。
[Abstract]:The dynamic lifting system of grab bucket mining ship has a large load and complex working conditions, so it is difficult for the ordinary transmission system to adapt to its working requirements.The dynamic lifting system model of grab is established by using AMESim simulation platform, and the typical working conditions of grab are simulated, which provides a good simulation platform for the research and design of liquid viscosity speed regulation system of grab ship.The thesis mainly includes:Firstly, the working characteristics of grab power system of grab mining ship are analyzed, and the necessity of applying hydraulic torque converter to grab lift system is expounded.Combined with the working characteristics of grab mining ship, the limitation of hydraulic torque converter and diesel engine working together is analyzed.Through the comparison of several regulating methods of hydraulic torque converter, the solution of series liquid viscous speed regulating clutch between hydraulic torque converter and diesel engine is determined.Secondly, the structure and working principle of liquid-viscosity speed regulating clutch are analyzed. Based on the mechanical properties of friction pair, rotary cylinder and oil film, the closed-loop control system model of liquid-viscosity speed regulating clutch is established by using AMESim simulation software.Finally, the principle of hydraulic torque converter is analyzed, and the simulation model of hydraulic torque converter is established by using AMESim software, and the effect of hydraulic torque converter is verified by simulation.The complete model of the grab hoisting system of mining ship is built. Through the simulation and analysis, the effect of the fluid viscosity speed regulating clutch and the rationality of the model are verified.
