汽车油箱与吊带的有限元分析及优化设计

王文竹1,程勉宏1,刘刚1,位君2(1.,110136;2.,110141):利用CATIA软件建立了某轿车油箱与吊带的三维实体模型通过有限元分析软件ANSYS,完成了油箱与吊带的有限元分析为了降低汽车的制造成本和轻量化的要求,利用APDL参数化设计语言对吊带进行了参数化三维建模,应用优化模块对吊带进行了优化设计,减小了质量:;;;APDL;:U464.136+.5:B:1006-0006(2010)04-0093-02FEAandOptimumDesignofAutomotiveTankandStrapsWANGWenzhu1,CHENGMianhong1,LIUGang1,WEIJun2(1.ShenyangAerospaceUniversity,Shenyang110136,China;2.ShenyangBrillianceJinbeiAutomobileCo.,Ltd.,Shenyang110141,China)Abstrac:tThethreedimensionalmodelofsomeautomotivetankandstrapsisestablishedbyCATIA.TheFEAiscompletedbyANSYS.Inordertomeetlowmanufacturingcostandlightweight,theparameterizedmodelofstrapsisestablishedbyAPDL.Optimaldesignofstrapsisobtainedbyoptimizationmodule,andthenitsweightisreduced.Keywords:Tank;Strap;Finiteelement;APDL;Optimaldesign,,,APDLANSYS,,,,11.1,,,CATIASPCC:28mm,2mm0.8mmmodelANSYSSOLID45,SHELL631,54008,125811Fig.1FiniteElementModelofTankandStraps1.2,ANSYS,,,,,,,0.1,,Z1.323,35.5MPa,270MPa0.284mm,2VonMises(:Pa)Fig.2VonMisesStressDiagramofTankandStraps:2009-09-0393374Vo.l37No.420108Tractor&FarmTransporterAug.,20103(:m)Fig.3DeformationDiagramofTankandStraps2,ANSYSAPDLBH,,100MPa()V,,ANSYS,,8,1,80.1237710-3m3,0.4443810-4m3,64.1%4567,74.5MPa,,0.981mm,1Tab.1OptmiizationResultB/mH/m(V)/m310.2800010-10.2000010-20.1237710-320.2677710-10.1457210-20.8626710-430.2310410-10.1692410-20.8642610-440.2430010-10.1617910-20.8691310-450.2194210-10.1093210-20.5300410-460.2049210-10.1023210-20.4630910-470.2014910-10.1007510-20.4484310-480.2005210-10.1003210-20.4443810-431),,35.5MPa,270MPa;,0.284mm2),ANSYS4Fig.4RelationCurvebetweenDesignVariableandOptmiizationSets5Fig.5RelationCurvebetweenObjectiveFunctionandOptmiizationSets6VonMises(:Pa)Fig.6VonMisesStressDiagramofOptmiizationSet7(:m)Fig.7DeformationDiagramofOptmiizationSet,8,64.1%():王文竹(1976-),,,,,(92)[2],,,.[J].,2003(7):4-7.[3],,,.ARM[M].:,2002.[4].ARM[J].,2004(9):14-15.[5],,.[J].,2004(5):5-8.[6].[J].,2005(5):38.[7],.CAN[J].,2005,36(9):151-152,163.():陆文昌,,,,;顾灶德,,,94420108
