密级：摘要汽车已成为人们日常生活必备的交通工具，汽车减震器在汽车零部件中占有极其重要地位。减震器是汽车悬架系统中的关键部件，减震器的性能就决定了悬挂系统的许多性能参数。而且减震器的好坏直接决定了汽车的乘坐舒适性和行驶的平顺性。随着计算机在软、硬件上的快速发展，虚拟设计无论是在理论，还是在计算技术方面都已取得巨大的进步。虚拟设计是较先进的现代设计方法。虚拟设计不仅可以大大降低开发成本，还缩短了开发周期，提高了企业的竞争力。所以，虚拟化设计越来越受到企业的欢迎。本文主要讲述了利用CAD软件UG对减震器各个零部件进行实体建模，然后着重分析了减震器的制造生产工艺，最后在UG软件的制图模块获得了完整的工程图纸。根据实践情况，利用通用有限元软件ANSYS对减震器的阀片进行有限元建模、计算、应力分析、应变分析，根据分析结果对减震器的阀片受力变形情况进行了解。关键词:汽车减震器，建模，产品设计AbstractAutomobilehasbecomeanindispensabletransportationmeansofourdailylife,andtheshockabsorberisanimportantpartofthecar.ShockabsorberisplayasanIimportantroleintheautomobilesuspensionsystem,becauseitdecideautomobilesuspensionsystemperformance.AnditalsodecidetheVehicleRideComfortandVehicleRideComfort.Withthecomputerinsoftwareandhardwareontherapiddevelopmentofvirtualdesign,whetherintheoryorinthecalculationofthevirtualdesignhavemadetremendousprogress.Virtualdesignisamoderndesignmethod.Virtualdesigncanhelpustoreducedevelopmentcostsandshortenthedevelopmentcycle,soitismoreandmorepopularbytheenterprise.ThisarticleintroducesthemodelingoftheshockabsorberbyCADsoftware,studyontheproductionoftheshockabsorberandgettheengineeringdrawinginUGsoftware.Atlast,accordingtopractice,usethegeneral-purposefiniteelementsoftwareANSYStofiniteelementmodeling,calculation,stressanalysis,strainanalysis,basedonananalysisoftheresultsofthevalvesoftheshockabsorberdeformationunderstandingofthesituation.Keywords：shockabsorberthree-dimensionalmodelingproductdesignII目录摘要.........................................................................................................................IAbstract........................................................................................................................II绪论..............................................................................................................................11.1选题的依据及意义..........................................................................................11.2减震器的结构及原理....................................................................................21.2.1减震器的结构及分类............................................................................21.2.2双向作用筒式减震器的工作原理........................................................31.3国内外减震器产品的发展状况及趋势..........................................................51.3.1国内汽车减震器产品的发展................................................................51.3.2国外汽车减震器产品的发展................................................................61.4本课题研究内容.............................................................................................7第二章减震器零部件的三维建模.............................................................................82.1UG软件介绍..................................................................................................82.2减震器各零部件的建模..................................................................................
