山东交通学院毕业设计（论文）摘要当今激烈的市场竞争迫使制造企业为求得生存和发展必须对多变的市场需求做出敏捷响应，不断地调整产品的设计和研发模式，并能快速的开发出新产品。而我国传统工程机械行业却由于新产品开发周期长、成本高，缺乏市场竞争力。虚拟样机技术的逐渐成熟为实现产品的快速开发，提高我国工程机械产品设计水平和市场竞争力提供了强有力的手段。本文将虚拟样机技术引入挖掘机设计开发领域，主要从以下几个方面进行了研究：结合当前挖掘机反铲工作装置的现状，应用软件ADAMS进行建模，并进行动力学分析；对工作装置的受力状况进行仿真，确定工作装置的铰点的受力状况和相应曲线，得出的结果与实际的工作情况是相符的。以挖掘工况为对象，对铲斗机构、斗杆机构和动臂机构进行了动力学分析,在ADAMS软件中建立了挖掘机工作装置，对其进行了仿真分析。关键词：挖掘机，虚拟样机技术，工作装置，ADAMS，仿真I---本文于网络，仅供参考，勿照抄，如有侵权请联系删除---钱广顺：挖掘机的虚拟样机技术探究AbstractFacingmoreintenseglobalmarketcompetition,manufacturingenterpriseshavetoadjusttheirproductdesignandfabricationmodefrequentlytomeettherapidlychangingmarketrequirement,Inordertoimprovethetraditionalconstructionmachinerydesignprocess,thisdissertationpresentsandstudiesVirtualPrototypingtechnology,whichhasbeenapprovedtobeapowerfulCADmethod.AndthenintroducesthenewtechnologyintothefieldofEngineeringMachinerydesigntosatisfytheurgentrequirementofdomesticmachinerydomain.Therewerefourpartspresentedandstudiedasfollowing:Thepresentsituationofcurrentexcavatorbackhoeworkingequipment,applicationsoftwareADAMSmodeling,anddynamicanalysis;Wesimulatethestressoftheworkingdeviceanddeterminethestressoftheworkingdeviceofhingedpointandthecorrespondingcurves,theresultsisinlinewiththeactualworksituation.Theworkingconditionofminingastheobject,thebucketmechanism,bucketrodmechanismandmovablearmmechanismforthedynamicanalysis.TheexcavatorworkingdeviceisestablishedintheADAMSsoftware,thesimulationanalysiswascarriedout.Keywords:Excavator,Virtualprototypetechnology,Workingdevice,ADAMS,Thesimulation---本文于网络，仅供参考，勿照抄，如有侵权请联系删除---II山东交通学院毕业设计（论文）目录前言....................................................................11虚拟样机技术概述........................................................21.1虚拟样机技术的概念................................................21.2虚拟样机技术的研究背景和意义......................................21.2.1虚拟样机技术的研究背景.......................................21.2.2虚拟样机技术的研究意义.......................................21.3虚拟样机技术特点..................................................41.3.1虚拟样机功能组成.............................................41.3.2虚拟样机技术的优点...........................................51.3.3虚拟样机技术的局限性.........................................51.4本章小结..........................................................52挖掘机虚拟样机技术......................................................72.1挖掘机的发展及研究现状............................................72.1.1国外发展动态及研究现状.......................................72.1.2国内发展动态及研究现状.......................................72.1.3挖掘机开发重点方向...........................................82.2挖掘机虚拟样机技术的提出..........................................92.3挖掘机虚拟样机技术的意义..........................................92.4本章小结.............
