ug风扇建模仿真设计说明书

III摘要面对激烈的市场竞争，制造业必须加速产品开发进程，缩短设计开发周期。计算机技术和计算机图形学的不断发展，为人们提供了强有力的工具，三维CAD/CAM/CAE集成化软件被广泛应用于制造业。与传统的装配设计相比，虚拟装配技术能满足并行工程的要求，实现产品可装配的设计，及时发现产品设计中的问题，提高装配质量和装配效果。研究是在UG软件设计平台上完成风扇的三维造型设计。UG软件具有很强大的实体造型、曲面造型、虚拟产品装配仿真、工程图生成等功能。论文论述了风扇虚拟设计中的关键环节，即零部件建模、虚拟装配、动态仿真设计等。并对产品设计中的虚拟设计方法与传统设计方法的差异、优越性进行了比对。通过可视化显示装配、干涉分析然后以求达到准确运动仿真，使生产真正在高效、高质量、低成本的环境下完成。关键词：三维造型设计；虚拟装配；运动仿真IVAbstractFacingwiththecompetitivemarket,manufacturersneedtoaccelerateproductdevelopmentprocess,shortentheproductdesignanddevelopmentcycle.Thecontinuousdevelopmentofcomputertechnologyandcomputergraphicsprovidespowerfultoolsforpeople,three-dimensionalCAD/CAM/CAEintegrationsoftwareiswidelyusedinmanufacturing.Comparedwiththetraditionalassemblydesign,virtualassemblytechnologytomeettherequirementsofconcurrentengineering,thedesignoftheirproductscanbeequippedwithtimelydetectionofproblemsinproductdesign,improvetheassemblyqualityandassemblyefficiency.ThisthesisbasedonUGproductdesignplatformforthefancompletedthethree-dimensionaldesign.Theshapestructureofverticalelectricfanisverycomplex,ifusingthetraditionalCADdrawingsoftwaretodesignwillbeverydifficult,UGcaneasilysolvethisproblem,theUGsoftwarehaspowerfulfunctionsofsolidmodeling,surfacemodeling,virtualassemblysimulation,engineeringdrawingandothers.Thispaperdiscussedthekeylinkoffanthatusingreversaldesignprogressfromthephysicaltothemoldinvirtualdesign,asthepartmodeling,virtualassembly,dynamicsimulationandthefaninjectionmolddesign.Thepaperalsocomparedtheadvantagesanddifferencesbetweenvirtualforproductdesigninthedevelopmentoftraditionaldesignmethods.Throughthevisualdisplayassembly,interferenceanalysisthentoachieveaccuratesimulationcampaignthatproducerealinhighefficiency,highquality,shorttime,lowcostenvironment.Keywords:3Dmodelingdesign;simulationassembly;movementsimulationV目录摘要...........................................................................................................................................IIIABSTRACT..................................................................................................................................IV目录............................................................................................................................................V1绪论.............................................................................................................................................11.1三维造型设计的现状和发展前景.......................................................................................11.2常用三维造型软件介绍.......................................................................................................21.3UG软件的介绍.....................................................................................................................21.4论文主要内容及研究意义...................................................................................................32基于UG的风扇设计.................................................................................................................52.1电风扇的发展现状...............................................................................................................52.2UG在产品中的设计思路.....................................................................................................52.3电风扇的建模设计分析.......................................................................................................52.3.1电风扇的虚拟装配介绍................................................................................................62.4电风扇主要零件的建模绘制...............................................................................................82.4.1电风扇罩的绘制............................................................................................................82.4.2电风扇叶的绘制..........................................................................................................102.4.3电风扇后座的绘制......................................................................................................122.4.4电风扇支架部分的绘制..............................................................................................142.4.5电风扇操作面板的绘制..............................................................................................152.4.6电风扇其他零件的绘制..............................................................................................162.5电风扇的装配体建模及爆炸图.........................................................................................172.5.1装配风扇本体..............................................................................................................172.5.2电风扇的爆炸视图及干涉分析..................................................................................213动态仿真...................................................................................................................................243.1关于动态仿真.....................................................................................................................243.1.1动态仿真的起源..........................................................................................................243.1.2仿真技术在产品开发制造过程中的应用...............................
