湖南科技大学毕业论文0车载机械自动调平机械系统设计与开发摘要本论文的题目是车载机械自动调平机械系统设计与开发。论文分为选题背景、方案论证、过程论述、结论总结四大部分。选题背景部分,我主要讲述了本设计课题的来源、目的、意义、应解决的问题及应该达到的技术要求和介绍系统其它结构。还简述了本课题在国内外的发展概况,为设计提供了指导思想。方案论证部分,我按照技术要求,对液压系统进行了分析,并设计了一套液压控制系统。过程论证析部分,我考虑了整个雷达受到本身重力和风力的影响,为了保证力学稳定性,使用了塔架杆来支撑主升油缸。我综合考虑了液压缸举升的高度和缸需要提供的动力,结合工作环境,从而选择了四级液压缸作为主升油缸。液压缸举升1.5吨的雷达和1.5吨的塔架,再加上受风力的影响,这对主升油缸的强度提出了要求,本部分通过计算可以确定满足强度要求的缸的内外径。塔架设计部分,设计了塔架三节每节的尺寸,以及塔架各节的连接。设计总结部分,我对本次设计过程进行了深刻的总结,为自己所学到了系统的分析问题而高兴,再次感受那些思考问题的过程与方法。关键词:四级液压缸;雷达;设计;自动调平系统。AbstractThetopicofmypaperisvehicle-mountedmachineautomaticallytransferredPingmechanicalsystemsdesignanddevelopment.Thispaperisdividedintofourparts:selectionofsubjectsbackground,programmeappraisal,processexpositions,conclusionssummarized湖南科技大学毕业论文1Selectionofsubjectsbackgroundpart,Idescribedthemainsourceofdesigntopics,objectives,significance,andshouldbeaddressedtothetechnicalrequirementsandotherstructuresonthesystem.Alsoonthetopicofdevelopmentprofileathomeandabroad,providingguidanceforthedesignideas.Becausethewholeradarantennawillbeaffectedbytheweightandwind,inordertomakesurethemechanicsstability,thenthesolutionisbyusingtowerframepoletosupportthemainpromotingcylinder.Thesecondpartisjusttheanalysesonthemechanicscapabilityofthetowerframepole.Programmeappraisalpartofthequestion,Ianalysedthehydraulicsysteminaccordancewiththetechnicalrequirements,andtodesignasetofhydrauliccontrolsystems.Analysisoftheprocessofverificationpart,Iconsidertheentireradarbyitselfgravityandwindeffects.Inordertoensurethestabilityofmechanics,Iusethetowertosupportthemainhydrauliccylinder.Onthepartofthemechanicstowerpoleperformanceanalysed.Iintegratedintothehydrauliccylinderup-downandhydrauliccylinderneedtoprovidethehighmomentumintheworkenvironment,thuschosenasamainor4hydrauliccylinder.1.5tonsofhydrauliccylinderup-downradarand1.5tonstowncoupledwiththeimpactofthewind,whichtheintensityofthefuelhydrauliccylinderorthedemandsofthissegmentbycalculatingtheintensitycanmeettherequirementsofmainhydrauliccylinder.Intheconclusion,Igiveathoroughsumming-upoftheprocessofmyproject.IfeelpleasedthatIhavelearnedtoanalyzeproblemgenerally,andhavereconsideredthemethodsandprocessofmyproject.Towerdesignpart,Iusethesecondpartofthecontents,designedtowersectionthreedimensions,andthetowersectionsconnected.Intheconclusion,Igiveathoroughsumming-upoftheprocessofmyproject.IfeelpleasedthatIhavelearnedtoanalyzeproblemgenerally,andhavereconsideredthemethodsandprocessofmyproject.Keyword:triple-levelhydrauliccylinder;design;Radar;automaticallylevelingsystem.湖南科技大学毕业论文2目录1选题背景.11.1雷达车的特点.41.2国内外高机动雷达发展状况.52方案论证.42.1主要技术指标.4湖南科技大学毕业论文32.2技术可行性.42.3升降天线车的液压系统说明.52.4测试系统的组成及功能.62.5主要技术难点分析.82.6与国内外同类产品技术对比分析.82.7推广应用价值.83过程论述.83.1雷达举升机构的力学分析.83.2缸的设计.123.3缸的连接及材料.163.4塔架的设计.233.5机动式车载雷达稳定性设计分析.244结论总结.315致谢.326参考文献.33
