本科畢業(yè)設(shè)計(jì)(論文)題目：采用調(diào)速閥的速度換接回路實(shí)驗(yàn)裝置設(shè)計(jì)系別：機(jī)電信息系專(zhuān)業(yè)：機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)：學(xué)生：學(xué)號(hào)：指導(dǎo)教師：2013年5月I用調(diào)速閥的速度換接回路實(shí)驗(yàn)裝置設(shè)計(jì)摘要速度換接回路的功用是使液壓執(zhí)行機(jī)構(gòu)在一個(gè)工作循環(huán)中從一種運(yùn)動(dòng)速度換到另一種運(yùn)行速度，因而這個(gè)轉(zhuǎn)換不僅包括快速轉(zhuǎn)慢速的換接，而且還包括兩個(gè)慢速之間的換接。實(shí)現(xiàn)這些功能的回路應(yīng)該具有較高的速度換接平穩(wěn)性。本文闡述了采用調(diào)速閥的速度換接回路實(shí)驗(yàn)臺(tái)的設(shè)計(jì)，主要對(duì)工作原理、結(jié)構(gòu)組成、參數(shù)計(jì)算等發(fā)面做了詳細(xì)的分析與研究，得出一套較為合適的方法來(lái)設(shè)計(jì)實(shí)驗(yàn)臺(tái)。主要通過(guò)查閱相關(guān)資料，應(yīng)用相關(guān)公式，從而對(duì)油箱進(jìn)行設(shè)計(jì)，然后來(lái)選擇液壓站的動(dòng)力裝置，確定電機(jī)與泵的安裝方式，最后再根據(jù)原理圖以及各項(xiàng)參數(shù)來(lái)進(jìn)行管路與管接頭的選擇，從而完成整個(gè)設(shè)計(jì)。論文首先綜述了國(guó)內(nèi)外液壓技術(shù)的研究進(jìn)展及研究現(xiàn)狀、分析課題的研究背景、闡述課題研究的意義和內(nèi)容。然后重點(diǎn)從原理設(shè)計(jì)、各回路的功能分析與選擇入手，從而選擇液壓元件，計(jì)算其性能是否符合指標(biāo)，最后校核溫升。關(guān)鍵詞：液壓基本回路；速度換接回路；實(shí)驗(yàn)裝置IITheDesignofSwitchingCircuitExperimentDeviceAdoptingtheSpeedRegulatorValveAbstractSpeedexchangecircuitsareusedtomakethehydraulicactuatortochangefromonemotiontoanotherrunningspeedinaworkcycle,sotheconversionincludesnotonlythefastswitchingforslow,butalsoincludestheexchangebetweenthetwoslow.LoopshouldachievethesefunctionswithhighspeedandstabilityThispaperdescribesthedesignofcircuitexperimentplatformforthespeedregulatorvalve,mainlyontheworkingprinciple,structure,parametercalculationetctodoadetailedanalysisandresearch,todesigntheexperimentwhichobtainsasetofsuitablemethod.Throughaccesstorelevantinformation,relatedformulasareused,thusthechoiceoftank,powerplantandthentoselectthehydraulicstation,theinstallationmodeofmotorandpump,finallytopipelineaccordingtotheschematicandthevariousparametersandselectionofpipejoints,soastocompletethewholedesign.Thepaperfirstsummarizestheanalysisofthestatusquo,andresearchprogressofstudyonthehydraulictechnologyathomeandabroadandthesignificanceofresearchbackground,describestheresearchtopics.Thenfocusfromtheprincipleofdesign,functionanalysisandselectionofcircuits,andchoosinghydrauliccomponents,itsperformanceisinlinewiththeindexcalculation,finallythechecktemperaturerise.KeyWords:Hydraulicbasiccircuit；Speedchangeovercircuit；ExperimentalinstallationIII主要符號(hào)表qp液壓泵得最大流量pp液壓泵最大工作壓力p1執(zhí)行元件最大工作壓力Δpλ沿程壓力損失KL系統(tǒng)的泄漏系數(shù)?運(yùn)動(dòng)粘度CT油箱散熱系數(shù)Re管道流動(dòng)雷諾數(shù)IV目錄1緒論....................................................................................................................11.1前言.................................................................................................................11.2題目背景及研究意義.....................................................................................21.3課題主要內(nèi)容.................................................................................................32液壓傳動(dòng)綜述.................................................................................................42.1液壓傳動(dòng)系統(tǒng)的組成.....................................................................................32.2液壓傳動(dòng)的優(yōu)缺點(diǎn).........................................................................................42.3液壓技術(shù)的應(yīng)用和發(fā)展?fàn)顩r.........................................................................52.4液壓系統(tǒng)設(shè)計(jì)要求及流程.............................................................................63速度換接回路液壓系統(tǒng)的設(shè)計(jì)................................................................73.1液壓系統(tǒng)的工況分析.....................................................................................73.2原理圖的擬定.................................................................................................73.2.1確定液壓泵類(lèi)型........................................................................................73.2.2原理圖設(shè)計(jì)................................................................................................73.3液壓系統(tǒng)參數(shù)的計(jì)算及液壓元件的選擇....................................................113.3.1液壓缸主要尺寸的確定...........................................................................113.3.2選擇液壓泵規(guī)格......................................................................................133.3.3液壓元件的選擇......................................................................................143.3.4確定管路尺寸..........................................................................................154液壓油路板的結(jié)構(gòu)與設(shè)計(jì).......................................................................164.1液壓油路板的結(jié)構(gòu).......................................................................................164.2液壓油路板的設(shè)計(jì).......................................................................................164.2.1分析液壓系統(tǒng)，確定液壓油路板結(jié)構(gòu)..................................................164.2.2液壓元件的布局及油孔的位置..............................................................164.2.3繪制液壓油路板零件圖..........................................................................175液壓站的設(shè)計(jì)................
