摘要在当今经济全球化、市场竞争日趋激烈的时代，新产品的开发时间成为企业能否在激烈的市场竞争中取胜的关键因素。传统的产品设计过程中重复计算、重复建模等工作量很大，一直困扰着产品开发人员，严重影响了产品的设计质量和效率。这种现象在凸轮的设计中尤为突显。针对这一问题，本课题利用Pro/E软件中的运动仿真模块对凸轮机构运动进行模拟仿真。本论文的主要研究内容有1、沟槽凸轮设计2、沟槽凸轮机构的零部件的实体建模3、沟槽凸轮机构的运动仿真关键词沟槽凸轮实体建模运动仿真ABSTRACTInthecompetitiveeraofeconomicglobalizationandincreasinglymarkets,thedevelopmenttimefornewproductbecomeakeyfactortowininthefiercecompetitionmarket.Thetraditionalproductdesignprocessofdoublecounting,suchasrepeatedheavyworkloadandmodelinghavetroubledtheproductdevelopmentstaff,aseriousimpactonproductdesignqualityandefficienct.Thisphenomenonisparticularlyonthedesignofcamhighlights.Addresswiththisproblem,thesubjectofusingthemovementsimulationmoduleofPro/Esoftwareonthecammovementsimulation.Inthispaper,themainresearchcontentsareasfollows1.Designingthegroovecam2.Modelingthemechanismpartsofgroovecam3.MotionsimulatingofthegroovecammechanismKeyWordsCamgroove,Modeling,MotionSimulation目录绪论.................................................................11.1本文研究的背景....................................................11.1.1我国凸轮机构的研究现状........................................11.1.2我国凸轮机构CAD/CAM的研究现状................................11.1.3国外凸轮机构及其CAD/CAM的研究现状...........................21.1.4我国凸轮CAD系统存在的问题....................................21.2本文研究的主要内容................................................21.3本文意义..........................................................31.4本章小结..........................................................32凸轮机构设计分析....................................................42.1从动件运动规律的选取..............................................42.1.1从动件常用的基本运动规律......................................42.1.2从动件运动规律的选取原则......................................42.2凸轮机构基本尺寸的设计............................................52.2.1凸轮机构压力角和基圆半径......................................52.2.2凸轮机构的偏距................................................62.2.3凸轮滚子半径..................................................62.3凸轮轮廓设计......................................................72.4机构简介..........................................................82.5本章小结..........................................................93凸轮机构的实体建模与装配...........................................103.1Pro/E软件简介...................................................103.2零部件的实体建模.................................................103.3装配原理简介与装配模型的建立.....................................123.3.1Pro/E仿真装配原理介绍.......................................123.3.2装配模型建立.................................................143.4本章小结.........................................................174凸轮机构的运动仿真.................................................184.1计算机仿真概述...................................................184.1.1计算机仿真的基本概念及特点...................................184.1.2计算机仿真技术在制造业中的应用...............................184.2Pro/E运动仿真简介...............................................194.2.1Pro/E运动仿真的特点.........................................194.2.2Pro/E运动仿真的基本术语.....................................204.2.3Pro/E运动仿真的步骤.........................................214.3凸轮机构的运动仿真...............................................214.3.1设置机构环境.................................................214.3.2分析.........................................................254.4本章小结.........................................................29结论................................................................30致谢................................................................31参考文献..............................................................32
