基于PDM的信息集成技术研究

基于PDM的信息集成技术研究浙江大学硕士学位论文摘要i摘要产品数据管理（ProductDataManagement，PDM）源于传统工程设计活动中产生的纸质产品图和原理图以及使用CAD工具制作的物料清单。而企业资源计划（EnterpriseResourcePlanning,ERP）使用PDM和BOM数据规划和协调公司所有的事务操作（比如销售订单管理、采购、成本会计和物流等）。PDM在企业的信息集成过程中可以被看作是起到一个集成“框架”的作用。各种应用程序诸如CAD/CAM/CAE、CAPP等将通过各种各“对象”而被集成进来，使得分布在企业各个地方、在各个应用中使用(运行)的所有产品数据得以高度集成、协调、共享，所有产品研发过程得以高度优化或重组。本论文在分析和研究当前PDM系统实际应用中主要出现的信息集成问题的基础上，针对其中的典型集成应用，研究了PDM与其它系统的集成模式，并进一步在Teamcenter的实际项目中，分析、验证了这些集成模式的可行性与有效性。完成的主要工作有:1、结合所在企业的实际情况，提出以Teamcenter为集成平台，将本企业实际加工中的CAD/CAM产品数据、工艺数据以及ERP进行全面集成管理的构想。2、建立了CAD/PDM集成模块软件包。此软件包以eclipserichclientplatform为实现平台，能方便地控制和访问CatiaV5中的数模数据及企业其它基础数据库中的数据，并可用于实现与Teamcenter系统的集成。其高效性和灵活性在本企业的实际应用中得到了验证。3、建立了PDM/ERP数据输出模块。此模块以IntegrationToolkit(ITK)和eclipsercp为实现平台，能实现PDM汇入/读取集成系统中间数据库数据。4、PDM集成编程实例。通过Teamcenter控制CatiaV5的三维数模，并将数据输出到ERP，实现了Teamcenter下的CAD/PDM/ERP集成功能。关键词：产品数据管理，企业资源计划，集成浙江大学硕士学位论文AbstractiiAbstractProductDataManagement(PDM)stemsfromtraditionalengineeringdesignactivitiesthatcreatedproductdrawingsandschematicsonpaperandusingCADtoolstocreatepartslists(BillsofMaterialstructures-BOM).ThePDMandBOMdataisusedinenterpriseresourceplanning(ERP)systemstoplanandcoordinatealltransactionaloperationsofacompany(salesordermanagement,purchasing,costaccounting,logistics,etc.).PDMintheenterpriseinformationintegrationprocesscanbeseenasanintegratedplayFrameworkrole.VariousapplicationssuchasCAD/CAM/CAE,CAPP,etc.throughavarietyofObjectandisintegrated,sothatthedistributionofvariousplacesintheenterprise,touseinvariousapplicationsofallproductdatatobehighlyintegration,coordination,sharing,alltheproductdevelopmentprocesscanbehighlyoptimizedorrestructured.InthispaperanalysisandstudyofthepracticalapplicationofthecurrentPDMsystem,mainlyintheintegrationproblem,basedontheintegrationofapplicationsforwhichatypicalstudytheintegrationofPDMandothersystemsmodel,andfurtherpracticalprojectsinTeamcenter,inordertoanalysis,verifythefeasibilityoftheseintegratedmodelsandeffectiveness.Themainresearchworksofthisthesisareasfollows:1.IntegrateeffectivelytheCAD/CAMproducts,processplanningdataandERPofourenterprisetakingtheTeamcenterasanintegrationplatform.2.AsoftwarepackageofCADandPDMintegrationissetup.ItisdesignedonEclipseRichClientPlatformasitsrealizingplatform.ItcancontrolandvisitsafelytheCAD/CAMdatainCatiaV5andotherdatainourenterprise'sdatabasestoestablishautomaticallyvariousBOMinformationdatabasesandworkoutprocessplanningdatafiles.ItcanbeusedintheintegrationwithTeamcenter.Itshighefficiencyandflexibilityareverifiedthroughourownenterprise'sactualuse.3.AmoduleofPDMandERPintegrationissetup.ItisdesignedbyIntegration浙江大学硕士学位论文AbstractiiiToolkit(ITK)inTeamcenterandEclipseRCPasitsrealizingplatform.Itcanexchangedatefromintermediatedatabase.4.AnintegrationofPDM/CAD/ERPexampleisfinished.RealizetheintegrationofCAD/PDM/ERPthroughputting3dimagedataofavehiclepartintomycustomizedmodule.KeyWords：PDM,ERP,Integration浙江大学硕士学位论文目录I目录摘要...............................................................................................................................iAbstract........................................................................................................................ii图目录........................................................................................................................III表目录.......................................................................................................................IV第1章绪论................................................................................................................11.1课题背景.............................................................................................................11.1.1制造业信息化面临的问题..........................................................................11.1.2PDM集成的必要性......................................................................................11.2研究意义.............................................................................................................21.3论文的组织结构.................................................................................................2第2章PDM综述.......................................................................................................32.1PDM概述.............................................................................................................32.1.1PDM简介......................................................................................................32.1.2PDM的历史..................................................................................................42.1.3PDM的研究现状..........................................................................................52.1.4PDM的发展趋势..........................................................................................52.2PDM在企业信息化中的地位.............................................................................62.3本章小结.............................................................................................................7第3章基于PDM的CAD/CAPP集成技术............................................................83.
