汽车球笼式等速万向节设计摘要速度驱动轴对于轿车来说是一个非常关键的部位。它直接关系到汽车的稳定性及力的传动性能。等速驱动轴的结构强度直接影响到它的性能与寿命，为实现综合的最佳标准化效果，需进行系列化设计。首先确定了汽车球笼式等速万向节的结构主参数及其上、下限，列出了若干基本参数，然后选择符合汽车要求的球笼式等速万向节进行设计，进而对产品的基本参数进行系列化设计，并阐述了产品系列化设计的作用。其主要研究工作如下：本文以国内的某种汽车作为研究对象，为这种型号的轿车选取前置的驱动球笼式等速万向节，选取的万向节在性能方面满足轿车的使用寿命要求，在结构上满足强度刚度性能。并对其基本参数加以设计和改进，再运用CATIA软件与ADAMS软件联合仿真分析对本文所设计的球笼式等速万向节传动轴运动学与动力学分析，检验了该球笼式等速万向节传动轴结构设计的正确性，并验证了结构设计的合理性，并有助于改进产品。关键词：球笼式等速万向节；参数化设计；动力学分析AbstractThespeeddriveshaftisakeypartofthecar.Itisdirectlyrelatedtothestabilityofthevehicleandforcetransmissionperformance.Constantspeedofthedriveshaftstructurestrengthdirectlyaffectitsperformanceandlife,andtheintensityoftheconstantspeeddriveshaftstructuredependsonthetransmissionpartsintheprocessoftheinternalcontactstressdistribution,size,howeverthetraditionaltestmethodcannotdeterminethecontactstressofcomplexstructure,sothatbyfiniteelementnumericalmethodtoaccuratelysimulatethetransmissionprocessisparticularlyimportant,alsoisthemainmethodofdesignanddevelopmentprocess.Inthispaper,onthebasisofrelatedliteratureathomeandabroadarereviewed.Theresearchofballcagepatternedconstantspeeduniversaljointastheresearchobject,toparametricdesignofproducts,iscurrentlywidelyusedtwokindsofracewaycrosssectionofuniversaljointkinematicsanddynamics,therespectsuchasthestaticcontactstresswasstudied,andtheraceofuniversaljointisoptimizedtoimprove.Theresearchworkisasfollows:Basedonadomesticmanufacturerbeforetheenginefrontdrivecarconstantspeeddriveshaftofballcagepatternedconstantspeeduniversaljointastheresearchobject,using3dreconstructiontechnology,usingthreecoordinatemeasuringmachinepartssizeprecisescannedintothecomputer,thenusingCATIAsoftwarecombiningADAMSsoftwareandthesimulationanalysisofthispaper,thedesignofballcagepatternedconstantspeeduniversaljointshaftkinematicsanddynamicsanalysis,validatethecorrectnessofballcagepatternedconstantspeeduniversaljointdriveshaftstructuredesign;Virtualprototypetechnologywasusedtoanalyzetheperformanceoftheconstantvelocityuniversaljointdriveshaft..Keywords：Ballcagetypeconstantvelocityuniversaljoint;Parametricdesign;Dynamicanalysis目录摘要........................................................................................................................2Abstract..................................................................................................................3第1章绪论.....................................................................................................61.1研究背景及课题来源..............................................................................61.2等速万向节简介......................................................................................81.3球笼式等速万向节简介........................................................................101.4国内外等速万向节的发展和研究概况................................................111.5论文研究的主要内容......................................................................
