基于CATIA的机械零件虚拟装配方法EE（EE指导教师：ee[摘要]：装配设计是产品设计过程的重要环节，随着虚拟现实技术的日益成熟，虚拟装配已成为其应用的重要研究方向，虚拟装配也为面向装配的设计提供了一种新的思路和方法。在传统的装配过程中,当一个零部件与另一个零部件装配失败后,只能返回装配结果,重新设计,重新生成样品,重新用真实装配来检验。这种装配关系的滞后检验,不但带来成本的巨大浪费,而且完全不符合快速反应市场的需要。随着计算机软件硬件技术的发展,在机械制造领域中,零部件如何装配加工、各零部件是否发生干涉等都能在虚拟装配环境中实现。借助虚拟装配技术,能在产品设计阶段就能了解设计结果的装配性。这种虚拟装配技术对小批量生产方式具有开发周期短、设计质量高,开发成本低等特点。本文分析了目前虚拟装配技术的发展状况，归纳总结了虚拟装配的关键技术和基本流程，介绍了装配的基本步骤及干涉检查的基本步骤。论文成功的实现了基于CATIA的装配及干涉检查，最后通过具体实例验证了方法的可行性和正确性。[关键词]:虚拟装配；CATIA；干涉检验；约束；检查碰撞VirtualassemblyofmechanicalpartsbasedonCATIAee（ee）Tutor:ee[Abstract]:Assemblydesignisanimportantpartofproductdesignprocess,benefitsmaturemouthofvirtualrealitytechnology,virtualassemblyhasbecomeanimportantresearchdirectionoftheapplication,thevirtualassemblydesignforassemblyandevaluationofanewwayofthinkingandapproach.Afterthefailureoftheassemblyofacomponentwithothercomponentsintheassemblyprocess,theonlyreturntotheassemblyresults,re-design,re-generatedsampletotest,re-usetherealassembly.Thisassemblybetweenthelagtest,notonlytobringthecostofenormouswaste,butdoesnotmeettherapidresponsetomarketneeds.Withthedevelopmentofcomputersoftwareandhardwaretechnologyinthefieldofmachinerymanufacturing,sparepartshowtoassembletheprocessing,thevariouspartsofinterventioncanbeimplementedinavirtualassemblyenvironment.Withthevirtualassemblytechnologyintheproductdesignstagetounderstandtheassemblyofthedesignresults.Thisvirtualassemblytechnologyforasmallbatchhasashortcycleofdevelopment,highqualityofdesign,lowcostofdevelopment.Thispaperanalyzesthecurrentstateofdevelopmentofthevirtualassemblytechnology,andsummarizesthekeytechnologiesandthebasicprocessofthevirtualassembly,thebasicstepsofthebasicstepsoftheassemblyandinterferencechecking.AsuccessfulrealizationofCATIA-basedassemblyandinterferencecheckinginthePaper,andfinally,throughconcreteexamplestoverifythefeasibilityandaccuracyofthemethod.[Keywords]:virtualassembly；CATIA；interferencetest；constraints；checkingthecollision目录第一章绪论…………………………………………………………………………………………………………………11.1引言.................................................................................................................11.2内外虚拟装配环境技术的发展与现状..........................................................11.2.1虚拟装配的发展现状.............................................................................11.2.2干涉检查的发展现状..........................................................................31.3研究背景及课题的提出.................................................................................41.4本章小结..............................................................................................................5第二章CATIA零件设计方法.....................................................................Error:Referencesourcenotfound2.1利用CATIAV5进行零件设计的方法………………………………………………………………Error:Ref...
