摘 要裝載機(jī)屬于鏟土運(yùn)輸機(jī)械類，是一種通過(guò)安裝在前端一個(gè)完整的鏟斗支撐結(jié)構(gòu)和連桿，隨機(jī)器向前運(yùn)動(dòng)進(jìn)行裝載或挖掘，以及提升、運(yùn)輸和卸載的自行式機(jī)械。它廣泛用于公路、鐵路、建筑、水電、港口和礦山等工程建設(shè)。裝載機(jī)具有作業(yè)速度快、效率高、機(jī)動(dòng)性好、操作輕便等優(yōu)點(diǎn)，因此成為工程建設(shè)中土石方施工的主要機(jī)種之一，對(duì)于加快工程建設(shè)速度，減輕勞動(dòng)強(qiáng)度，提高工程質(zhì)量，降低工程成本都發(fā)揮著重要的作用，是現(xiàn)代機(jī)械化施工中不可缺少的裝備之一。這次設(shè)計(jì)采用先進(jìn)的現(xiàn)代設(shè)計(jì)方法，對(duì)這種輪式裝載機(jī)工作裝置進(jìn)行了總體設(shè)計(jì)到零部件設(shè)計(jì)。主要包括輪式裝載機(jī)工作裝置的關(guān)鍵零部件，如鏟斗、連桿機(jī)構(gòu)以及轉(zhuǎn)斗油缸、舉升油缸等，并對(duì)重要零件進(jìn)行了剛度、強(qiáng)度分析。應(yīng)用 CATIA 軟件對(duì)輪式裝載機(jī)工作裝置整體進(jìn)行設(shè)計(jì)，并用它對(duì)本次設(shè)計(jì)進(jìn)行立體展示表達(dá)。關(guān)鍵詞： 裝載機(jī)； 機(jī)械化； 工作裝置ABSTRACTLoader of soil belonging to the transport machinery，Through the installation of a front-end in a bucket full support structure and linkage, Random forward movement for loading or excavation, And the upgrading, transportation and unloading of self-propelled machinery. It widely used in highway, railway, construction, utilities, ports and mines, and other construction projects. Loader is operating speed, high efficiency, good mobility, the advantages of operating the Light, So as the construction of earth and stone in the construction of one of the main machine, speed up the construction speed and reduce labor intensity and improve quality, lower costs of the project has played an important role in the construction of a modern mechanized equipment indispensable one.The design of the modern use of advanced design methods, wheel loaders working on such a device design to design components. Wheel Loader work includes installation of critical components, such as the bucket, linkage and the fuel tank to the bucket, lifting the oil tanks, and carry out important parts of the stiffness, strength analysis. Application of CATIA software installed on the wheel loader work for the overall design and its use of this design three-dimensional display of expression.Keywords：Loader； Mechanization；Work-Equipment目 錄1 緒論 .11.1 輪式裝載機(jī)概述 11.1.1 裝載機(jī)簡(jiǎn)介 .11.1.2 裝載機(jī)的主要技術(shù)性能參數(shù) .11.1.3 裝載機(jī)的用途 .21.1.4 裝載機(jī)的分類 .31.2 輪式裝載機(jī)應(yīng)用技術(shù)發(fā)展 51.2.1 國(guó)外輪式裝載機(jī)發(fā)展現(xiàn)狀 .61.2.2 國(guó)外輪式裝載機(jī)發(fā)展趨勢(shì) .121.2.3 國(guó)內(nèi)輪式裝載機(jī)發(fā)展現(xiàn)狀 .131.2.4 國(guó)內(nèi)輪式裝載機(jī)發(fā)展趨勢(shì) .141.3 本章小結(jié) 152 裝載機(jī)工作裝置總體設(shè)計(jì) .162.1 工作裝置的總體結(jié)構(gòu)與布置 162.2 工作裝置連桿機(jī)構(gòu)的結(jié)構(gòu)形式與特點(diǎn) 182.3 工作裝置自由度的計(jì)算 242.4 工作裝置總體設(shè)計(jì) 263 ZL50 裝載機(jī)工作裝置設(shè)計(jì) 273.1 工作裝置的設(shè)計(jì)要求 273.1.1 工作裝置工作性能 .273.1.2 對(duì)工作裝置的要求 .273.2 鏟斗設(shè)計(jì) 273.2.1 鏟斗的結(jié)構(gòu)形式 .283.2.2 鏟斗的分類 .303.2.3 鏟斗斷面形狀和基本參數(shù)確定 .313.2.4 鏟斗容量的計(jì)算 .343.3 工作裝置連桿系統(tǒng)設(shè)計(jì) 353.3.1 機(jī)構(gòu)分析 .353.3.2 尺寸參數(shù)設(shè)計(jì) .373.3.3 連桿系統(tǒng)運(yùn)動(dòng)分析 .463.4 工作裝置靜力學(xué)分析及強(qiáng)度校核 503.4.1 靜力學(xué)分析 .503.4.2 強(qiáng)度校核 .553.5 液壓缸設(shè)計(jì) 583.5.1 液壓缸的類型和結(jié)構(gòu) .583.5.2 液壓缸基本參數(shù)設(shè)計(jì) .594 CATIA 軟件的應(yīng)用 .624.1 CATIA 軟件的介紹 624.2 CATIA 軟件的應(yīng)用 644.2.1 零件設(shè)計(jì) .644.2.2 產(chǎn)品設(shè)計(jì) .67結(jié)論 .69參考文獻(xiàn) .70附錄 .71翻譯部分 .72英文原文： .72中文譯文： .82致謝 .88
