文档介绍：减速器轴系零部件参数化CAD系统的研究与开发万方数据 ABSTRACT AB STRACT Reliability is an important indicator about thequality the design ofreliability is an important link to ensure quality indesign ofmechanical many bustnesses are using CAD software todesign product,but general CAD software can’tproduce corresponding parts model according to user's stillneed ording tothespecific method tobuild model stepbVstep,because thesoftware lacksreliability function,it isdifficult to ensure the reliability of the the mechanical used for driving motivation andsports,everywhere can found the trace ofgear reducer·1Thispaper derived new shalting parts ponents ofthree—dimensional model directly, according toreducer pans sizedesigned by CAD theworkload ofthe desi凹ers willbe greatly reduced and thedesign efficiency willbeimproVed· What,s more。it facilitates the follow—up finite element analysis,virtual manufacturing andCAM,,this dissertation carrles outthe and development of the two—stage cylindrical gear reducer shafting pans parametric CAD tasks are asfollows: overall analysis and design ofthesystem:to develop thetwo-stage cvlindrical gear reducer shafting paKs parametric CAD system,by using the software ofvc++,object—oriented technology anddatabase technology·After users interface selected theinitialconditions,this system can realizethe transmission ratio ofthedistribution,use conventional design methocI torealize high and low grade gear transmission sizedesign and thetwo-stage cvlindrical gear reducer structure design ponents,and realizedata tiles output about design andcalculation results. design:adding reliability design module intoparametric CAD svstem,written checking and reliability design program in the situatlon ot shaRing parts satisfying target reliability,then using PSO(Particle Swarm OF}timization、algorithm situation tooptimize design products·Finally achleVe data fi
