本科毕业设计论文题目车载雷达液压升降系统设计系别机电信息系专业机械设计制造及其自动化班级学生学号导师2013年05月I车载雷达液压升级系统设计摘要随着国际形势的动荡,局部战争的不断爆发,现代武器装备的不断更新,现代战争已进入了电子战,信息战时代,传统的机动型雷达已经不能满足现代战争的需要。各国为了提高自己的防卫,跟踪,识别和反击能力,高机动地面雷达应运而生。天线快速,可靠地机动架设和撤收是车载雷达的基本要求之一。按传动系统的不同,雷达天线升降机构可分为机电式和液压式。与机电式相比,在输出同样功率的条件下,液压式的体积和质量小,承载能力大,可以完成较大重量雷达天线的架设,还可大大简化机械结构,减少机械零部件的数目,也便于实现自动控制。随着科技的发展,液压式传动系统已逐渐在雷达天线升降机构中被采用。本设计采用一种翻转式液压举升机构及其液压系统,可实现对较大型天线的高架,并且在天线的举升过程中,天线的姿态不变,架撤收过程平稳,可靠,快速关键词液压升降系统汽车雷达IIThedesignofcarradarhydraulicupgradesystemAbtractTurmoilastheinternationalsituation,localwarsbreakingout,constantlyupdated,modernweaponsandequipmentofmodernwarfarehasenteredtheelectronicwarfare,informationwarfareera,thetraditionalmobileradarcannotmeettheneedsofmodernwarfare.Countriesinordertoimprovetheirdefense,tracking,identification,andfightbackability,highmotorizedgroundradarcameintobeing.Fast,reliablemotorizedantennaerectionanddismantlingisoneofthebasicrequirementsoftheautomotiveradar.Fordifferencesinthetransmissionsystem,theradarantennaliftingmechanismcanbedividedintoelectromechanicalandhydraulic.Withelectromechanicalcomparedtothesameoutputpowerconditions,thehydraulicvolumeandmassofsmallcarryingcapacity,thelargerweightoftheradarantennacanbecompletederection,butalsogreatlysimplifiesthemechanicalstructure,reducingthenumberofmechanicalparts,alsoeasytoachieveautomaticcontrol.Withthedevelopmentofscienceandtechnology,thehydraulicdrivesystemhasbeengraduallytheradarantennaliftingmechanismisused.Thisdesignusesafliphydraulicliftingmechanismanditshydraulicsystem,canbeelevatedtothelargerantenna,andintheprocessofliftingoftheantenna,theantennaofthesameattitude,erectingtheclosingprocessissmooth,reliable,fastKeywordshydraulicliftsystemcarsradarIII目录1绪论........................................................................................................................11.1课题研究背景.................................................................................................11.2雷达车的特点.................................................................................................11.3国内外机动雷达现状分析.............................................................................21.4设计的目的及任务.........................................................................................32举升系统总体方案设计.........................................................................................52.1天线升降装置对液压系统的要求..................................................................52.2总体技术方案..................................................................................................52.3系统主要技术参数的确定..............................................................................72.4举升机构液压系统及工作原理的设计..........................................................92.5设计特点分析................................................................................................113举升机构的液压系统设计计算...........................................................................123.1主液压缸的设计...........................................................................................123.1.1液压缸缸体厚度计算......................................................................133.2.2液压缸长度确定..............................................................................133.2.3缸体的材料......................................................................................143.3.4活塞杆直径的设计..........................................................................143.3.5活塞杆的材料..................................................................................153.2副液压缸的设计...........................................................................................173.2.1液压缸缸体厚度计算......................................................................173.3活塞的设计...................................................................................................183.3.1活塞的材料......................................................................................183.4导向套的设计与计算...................................................................................193.4.1最小导向确定长度H的.................................................................193.4.2导向套的结构..................................................................................203.4.3导向套的材料..................................................................................203.5端盖和缸低的设计与计算.........................................................................203.5.1缸盖的材料......................................................................................213.6缸体的长度确定.........................................................................................223.7缓冲装置的设计...........................................................................................223.8密封件的选用...............................................................................................223.9动密封部位密封圈的选用...........................................................................23IV3.10液压缸的安装连接结构.............................................................................233.11液压缸油口的设计.....................................................................................244液压泵
