摘要21世纪是汽车工业飞速发展的时代，汽车工业逐步成为许多国家的支柱产业。为了控制汽车产品质量，提高汽车品质，势必对其总成及零部件提出更高更严格的要求变速器是汽车传动系中一个重要总成。同步器是汽车变速器的重要部件，主要用于汽车行驶中平稳变速换档，操纵轻便灵活，消除冲击噪音和降低汽车油耗。同时，防止变速箱齿轮的损坏，直接影响变速器寿命。因此，研制先进的同步器试验系统，对提高汽车试验技术有着重要意义。同时，汽车是一个由许多种零部件组成的复杂的机械系统。对于产品开发所需的许多技术资料，目前尚不能通过理论计算得到，只能通过试验，因此有人说“汽车是试验出来的”。国外汽车工业由于发展时间较长，且对试验检测工作十分重视，在资金上给予了巨大的投入，一般都有较为齐全的试验装备。再加上严格管理和精良的加工设备，与国内形成了较大的差距。所以，我国汽车厂必须加大对试验检测设备的投入，才能大大缩短同国外同类厂家在试验手段上的差距，有利于我国汽车产品在国内外的竞争能力。关键词：同步器机械手控制系统实验AbstractInthe21stcenturyistheeraofrapiddevelopmentofautomobileindustry,carindustryhasbecomethepillarindustryinmanycountries.Inordertocontrolthequalityofautomobileproductsimprovethequalityofthecar,isboundtotheassemblyandpartsputforwardhigherandmorestringentrequirements.Transmissionisanimportantassemblyintheautomobiledrivetrain.Synchronizerisoneoftheimportantparts,autotransmissionismainlyusedforthecaringearshiftsmoothly,flexiblemanipulation,eliminatethenoiseimpactandlowerfuelconsumption.Atthesametime,preventtransmissiongearisdamaged,directlyaffectingtheservicelifeofthetransmission.,therefore,todevelopadvancedsynchronizertestsystem,toimprovetheautotesttechnologyhasimportantsignificance.Atthesametime,theautomobileisacomplicatedmechanicalsystemiscomposedofmanykindsofspareparts.Formanyofthetechnicalinformationneededforproductdevelopment,atpresentcannotbeobtainedbytheoreticalcalculation,canonlythroughthetest,sosomepeoplesaythat\"acaristest\".Foreignautomotiveindustrybecauseofthedevelopmentforalongtime,andtotestworkveryseriously,giventhehugeinvestmentinthecapital,usuallyhasrelativelycompletetestequipment.Coupledwiththestrictmanagementandexcellentprocessingequipment,withthedomesticformedalargergap.CarfactoryinChina,therefore,mustincreaseinvestmentintestequipment,andcangreatlyshortenthegapofsimilarforeignmanufactureronthetestmethod,isconducivetoChina'sautoproductsindomesticandinternationalcompetitionability.Keywords:SynchronizerManipulatorControlsystemExperiment目录1绪论........................................................................................................................21.1同步器...................................................................................................................21.2变速器.....................................................................................................................51.2.3自动变速器的分类.........................................................................................61.2.4自动变速器的发展状况.................................................................................71.2.5自动变速器未来的发展趋势.........................................................................91.2.6实现车辆自动变速的意义...........................................................................101.3车辆自动换挡规律简介.....................................................................................101.3.1单参数换挡规律.....................................
