题目：基于UG奥迪汽车车身的曲面设计与加工分析研究自动化（数控技术）专业：摘要本次课题是基于UGNX软件对奥迪汽车车身模型的曲面进行设计和加工。在整个设计过程中，以目前国际上最流行的三维造型和加工软件之一的UGNX6.0为平台，设计出奥迪汽车车身的曲面造型和实体模型，并在此基础上进行虚拟制造和数控加工。随着计算机技术的发展，UG作为一体化的CAD/CAE/CAM（计算机辅助设计/计算机辅助分析/计算机辅助制造）软件在各个领域得到了广泛地应用。该软件以工作站和微机为平台，UGCAD与UGCAM功能之间紧密相连，确保了CAM模型与CAD设计的同步性。它是工业界中最好且最具代表性的数控软件之一，利用它可以针对任何加工任务生成优化和可用的数控加工路径。本次设计，以目前市场中知名高档汽车之一的奥迪汽车模型为参考，首先用UG软件的CAD模块绘制出车身曲面并进行实体建模；然后用UG软件中的分析功能对模型进行曲面分析与优化；再运用UG软件的CAM模块对汽车车身模型进行虚拟制造，最后通过计算机与RS232通信接口，进行数控机床的DNC加工，最终生成产品模型。关键字：UG；奥迪汽车；实体建模；虚拟制造；数控加工ABSTRACTThispaperpresentsUG-basedComputer-AidedDesignandManufaturingofthecurvedfaceoftheAodiCarmodel.Inthewholedesignprocess,thedesignandmanufacturingsoftwareisUGNX6.0.AnduseUGsoftwaretoproducethemould,andthenanalysessurfaceanddimenationofthemouldbyanalysingfunctionofUGsoftware.Alongwithcalculatortechnicaldevelopment,theUGthatastheCAD/CAMsoftwareturntogetateachrealmbroadlyapplied.Thissoftwaretakestheworkstationandthecomputerasterrace,thefunctionoftheUGCADandUGCAMisclosetoconnectwitheachother,insuringthesynchronizationoftheCAMmodelandCADdesign.ItisoneofthebestandthemostrepresentativeNCsoftwaresintheindustry,makinguseofitcanproduceexcellentandavailableNCprocesspathaimatanyprocessmission.Themainprocessis:SelectthepopularAodiCarincurrentmarket.FirstusesUGsoftwaretosetupthemould,andthenanalysesurfaceanddimenationofthemouldbyanalysingfunctionofUGsoftware.Afterthat,completesthevirtualmanufacturingofthemouldbyCAMfunctionofUG.Finally,transfersNCcodetoNCMachineToolwithRS232andthenmanufacturstheproduct.Suchafinishedproductismade.Keywords:UG；AodiCar；Substantialitymould；virtualmanufacturing；NCmanufacturing目录第一章绪论...................................................................................................................11.1引言......................................................................................................................11.2选题背景及意义..................................................................................................11.3研究现状..............................................................................................................21.4设计步骤及内容..................................................................................................31.5本文的结构..........................................................................................................3第二章UG软件的介绍................................................................................................42.1UGNX6软件概述.........................................................................................42.2UGNX6软件的常用模块.............................................................................42.2.1建模............................................................................................................42.2.2外观造型设计.............................................................................................
