2023年第9期基于知识的螺纹连接类零件智能设计宋艳玲1,潘崇来2,周秋忠1(1.沈阳理工大学汽车与交通学院,辽宁沈阳110159;2.杭州朴石网络技术有限公司,浙江杭州310053)摘要:传统的三维设计以点、线、面为基础元素进行建模,可能会使零部件间的联系割裂,对于复杂的产品,设计人员需要投入大量的时间进行设计,并没有产生很大的价值。本文总结了螺纹连接类零件设计流程与相关形状特征,利用自主研发的基于知识的流程定制系统进行设计流程的可视化表达与推理,并在CATIA软件中利用二次开发功能对螺纹连接类零件进行设计,将螺纹连接件的结构信息、被连接件的开孔信息和装配信息以特征代码的形式封装到动态链接中,利用基于知识的流程定制系统将特征和设计流程结合,实现特征的快速重用及连接零部件的快速重用,大大减少了设计人员的设计时间,提高了设计效率。关键词:螺纹零件;形状特征;二次开发;智能装配中图分类号:TH131.3文献标识码:A文章编号:1674-957X(2023)09-0088-03IntelligentDesignofThreadedPartsBasedonKnowledgeSongYan-ling1,PanChong-lai2,ZhouQiu-zhong1(1.SchoolofAutomobileandTransportation,ShenyangLigongUniversity,ShenyangLiaoning110159,China;2.HangzhouPurestoneNetworkTechnologyCo.,Ltd,HangzhouZhejiang310053,China)Abstract:Traditional3Ddesigntakespoint,lineandsurfaceasbasicelementsformodeling,whichmaybreaktheconnectionbetweenparts.Forcomplexproducts,designersneedtospendalotoftimeondesign,whichdoesnotproducegreatvalue.Thispapersummarizesthedesignprocessandrelevantshapefeaturesofthreadedconnectionparts,usestheself-developedknowledge-basedprocesscustomizationsystemtovisuallyex-pressandreasonthedesignprocess,andusesthesecondarydevelopmentfunctioninCATIAsoftwaretodesignthreadedconnectionparts,encapsulatingthestructuralinformationofthreadedconnectionparts,theopeningin-formationofconnectedpartsandassemblyinformationintodynamiclinksintheformoffeaturecodes,Theprocesscustomizationsystembasedonknowledgeisusedtocombinefeaturesanddesignprocessestorealizetherapidreuseoffeaturesandconnectingparts,whichgreatlyreducesthedesigntimeofdesignersandimprovesthedesignefficiency.Keywords:Threadedparts;Shapecharacteristics;Secondarydevelopment;Intelligentassembly基金...
