快速回路实验台的设计说明书.doc

XXXX大学毕业设计说明书I摘要液压传动技术的发展旨在研究液压系统各类元件结构、作用、工作原理、应用方法,以及组成液压系统的特点。随着液压技术、控制理论、微型计算机、测量测试技术、数字信息处理、可靠性技术的发展,新的液压实验台已朝着高速、高效、智能化、多功能化、多样化的液压计算机辅助测试CAT方向发展。本文阐述了快速回路实验台的设计,主要对工作原理、结构组成、参数计算等发面做了详细的分析与研究,得出一套较为合适的方法来设计实验台。主要通过查阅相关资料,应用相关公式,从而对油箱进行设计,然后来选择液压站的动力装置,确定电机与泵的安装方式,最后在根据原理图以及各项参数来进行管路与管接头的选择,从而完成整个设计。论文首先综述了国内外液压技术的研究进展及研究现状、分析课题的研究背景、阐述课题研究的意义和内容。然后重点从原理设计、各回路的功能分析与选择入手,从而选择液压元件,计算其性能是否符合指标,最后在校核温升。关键词液压基本回路快速回路实验台XXXX大学毕业设计说明书IIAbstractDevelopmentofhydraulicdrivetechnologyistostudythehydraulicsystemofallkindsofelementstructure,function,workingprinciple,applicationmethod,andthecharacteristicsofhydraulicsystem.Withthedevelopmentofhydraulictechnology,controltheory,computer,measurementandtestingtechnology,digitalsignalprocessing,reliabilitytechnologydevelopment,hydrauliccomputeraidedtesthydraulicteststandnewtowardhighspeed,highefficiency,intelligent,multifunctional,diversifieddevelopmentCAT.Thispaperdescribesthedesignofthemaincircuit,theworkingprinciple,structure,parametercalculationetctodoadetailedanalysisandresearch,todesigntheexperimentobtainsasetofsuitablemethod.Throughaccesstorelevantinformation,relatedformulas,thuscarriesonthedesigntothefueltank,powerplantandthentoselectthehydraulicstation,theinstallationmodeofmotorandpump,finallytopipelineaccordingtotheschematicandthevariousparametersandselectionofpipejoints,soastocompletethewholedesign.Thepaperfirstsummarizestheanalysisofthestatusquo,andresearchprogressofstudyonthehydraulictechnologyathomeandabroadandthesignificanceofresearchbackground,describestheresearchtopics.Thenthefocusfromthedesignprinciple,thecircuitanalysisandselectionoffunction,thustheselectionofhydrauliccomponents,itsperformancemeetstheindexcalculation,thetemperatureriseincheck.KeywordsHydraulicbasiccircuitcircuitexperimentplatformXXXX大学毕业设计说明书III目录摘要........................................................................................................................................IAbstract.................................................................................................................................II第一章绪论.........................................................................................................................11.1课题背景及其意义..................................................................................................11.2液压实验台的国内外研究现状.............................................................................11.3实验台的组成..........................................................................................................11.4课题研究的主要内容.............................................................................................21.5本章小结.................................................................................................................2第二章设计任务的主要方案.............................................................................................32.1本课题将要完成的主要任务.................................................................................32.2本课题的关键问题及技术路线............................................................................32.2.1液压系统设计步骤.....................................................................................32.2.2液压执行器设计压力的选取.....................................................................32.2.3制定基本方案和绘制液压系统图.............................................................42.3本章小结.................................................................................................................5第三章液压系统执行元件的设计.....................................................................................63.1执行元件类型.........................................................................................................63.2系统压力的初步确定.............................................................................................63.3液压执行元件的主要参数.....................................................................................73.3.1液压缸内径与活塞杆外径.........................................................................73.3.3活塞杆的强度计算和稳定性校核..............................................................83.3.4液压缸壁厚,最小导向长度计算.............................................................93.4液压缸的结构设计...............................................................................................113.4.1缸筒与缸盖...............................................................................................113.4.2活塞与活塞杆...........................................................................................123.4.3缓冲装置...................................................................................................133.4.4排气装置...................................................................................................143.4.5密封装置...................................................................................................143.5本章小结...............................................................................................................14第四章液压系统的设计分析...........................................................................................164.1拟定液压系统原理图....
