【摘要】：盾構(gòu)機是集機械、電氣、液壓、測量、控制等多學科于一體的,專門用于地下隧道工程的大型機械設(shè)備。刀盤作為盾構(gòu)機的核心部件,其結(jié)構(gòu)復(fù)雜,需結(jié)合具體施工地質(zhì)情況進行設(shè)計分析。本文對盾構(gòu)機刀盤驅(qū)動液壓系統(tǒng)進行設(shè)計,通過AMESim仿真軟件對盾構(gòu)機刀盤驅(qū)動液壓系統(tǒng)進行仿真分析。這將有利于提高我國盾構(gòu)機的設(shè)計制造技術(shù)水平,為以后的盾構(gòu)機設(shè)計制造工作奠定基礎(chǔ)。本文主要研究內(nèi)容如下:首先,綜述了盾構(gòu)機的施工原理及分類,介紹了盾構(gòu)機國內(nèi)外發(fā)展現(xiàn)狀和發(fā)展近況,并對幾種驅(qū)動方式做了比較,最后概述了本課題的研究內(nèi)容以及主要進行的研究工作。其次,針對刀盤驅(qū)動液壓系統(tǒng)的設(shè)計要求,采用變量泵—變量馬達的閉式容積調(diào)速回路進行系統(tǒng)設(shè)計,并分析其結(jié)構(gòu)組成和工作原理,根據(jù)系統(tǒng)主要技術(shù)參數(shù),進行參數(shù)計算、性能驗算以及液壓元件的選型,最后設(shè)計了集成閥塊和液壓泵站。再次,對主要液壓元件進行數(shù)學建模,并從變量泵—定量馬達系統(tǒng)和定量泵—變量馬達系統(tǒng)入手,建立變量泵—變量馬達系統(tǒng)的數(shù)學模型,并就影響刀盤驅(qū)動液壓系統(tǒng)的主要參數(shù)提出優(yōu)化方案。最后,采用AMESim軟件對系統(tǒng)各回路進行建模,設(shè)定工程參數(shù),搭建刀盤驅(qū)動液壓系統(tǒng)模型,并對系統(tǒng)在不同工況下進行仿真分析,得出刀盤轉(zhuǎn)速能隨調(diào)速信號變化而變化,系統(tǒng)具有良好跟隨性,采用AMESim和Simulink對刀盤驅(qū)動液壓系統(tǒng)進行聯(lián)合仿真,得出系統(tǒng)具有良好的穩(wěn)定性、適應(yīng)性,最后利用北方重工正在調(diào)試的設(shè)備進行實際驗證。
[Abstract]:The shield machine is a kind of large mechanical equipment which integrates mechanical, electrical, hydraulic, measurement and control disciplines and is specially used in underground tunnel engineering. As the core component of shield machine, the structure of the cutter head is complex. It is necessary to design and analyze the concrete geological conditions of construction. This paper designs the hydraulic system driven by the cutter head of shield machine. The hydraulic system driven by cutter head of shield machine is simulated and analyzed by AMESim software, which will help to improve the technical level of design and manufacture of shield machine in China. The main contents of this paper are as follows: firstly, the construction principle and classification of shield machine are summarized, and the present situation and development of shield machine at home and abroad are introduced. Finally, the research contents and main research work of this subject are summarized. Secondly, the design requirements of the hydraulic system driven by the cutter head are discussed. The system is designed by using the closed volumetric speed regulation loop of variable pump and variable motor, and its structure composition and working principle are analyzed. According to the main technical parameters of the system, parameter calculation, performance checking calculation and type selection of hydraulic components are carried out. Finally, the integrated valve block and hydraulic pump station are designed. Thirdly, the mathematical model of the variable pump-variable motor system and the quantitative pump-variable motor system are established. Finally, AMESim software is used to model each loop of the system, set up the engineering parameters, and set up the hydraulic system model of the cutter drive hydraulic system. The simulation analysis of the system under different working conditions shows that the speed of the cutter head can change with the speed control signal, and the system has good following performance. AMESim and Simulink are used to simulate the hydraulic system driven by the cutter head. It is concluded that the system has good stability and adaptability. Finally, the equipment being debugged by Northern heavy Industry is used for practical verification.
