用maxwell对变压器的建模仿真教程

该变压器模型采用EE型铁芯，通入单向交流电，通过maxwell的3D模型构建为两层，分为初级和次级同轴绕制。1•建模(MOdel)PrOjeCt>InSertMaXWelI3DDeSignFile>Saveas>transformer选择求解器类型：MaXWelI>SOIUtiOnType>MagnetOStatiC创建变压器铁芯框架DraW>BOXPOSition：(,-15,0)BOX尺寸：(XSize,YSiZe)ZSiZe)>(11,30,26)DraW>BOXPOSition：(,,5)BOX尺寸：(XSize,YSiZe)ZSiZe)>(11,,16)选中Box2Edit>DUPIiCate>ArOUndAXiSAxis:ZAngIe:180degTOtaInumber:2选中BOXI,Box2,Box2_lMOdeIer>BOOIean>SUbtractBIankParts:BOXITOOIPartS:Box2,Box2_l不要选：UCIOnetoolObjeCtSbefOreSUbtracting”DraW>BOX(创建GaP(缺口))POSition：(,15,)BOX尺寸：(XSiZe,YSiZe)ZSiZe)>(11,30,)选中BOXI,Box3MOdeIer>BOOIean>SUbtractBIankParts:BOXITOOIPartS:Box3不要选：UCIOnetoolObjeCtSbefOresubtracting”选中BoXIMOdeIer>BOOIean>SeParateBOdieS将分离后的模型分别重命名为:UCOre_upn(原BOXI)和“Co:re_down”将两者的重设为：“ferrite”为铁氧体的材料属性。创建线圈初级绕组MOdeIer>GridPIane>YZDraW>ReCtangIePOSition：(0,6,)BOX尺寸：(XSize,YSize,ZSiZe)>(0,1,15)MOdeIer>GridPIane>XYDraW>ReCtangIePosition：(-6,-6,13)BOX尺寸：(XSiZe,YSiZe)ZSiZe)>(12,12,0)选中ReCtangIe2MOdeler>DeleteLaStOPeration(形成ReCtangleI围绕的轨迹)选中ReCtanglel,ReCtangIe2DraW>SWeeP>AIOngPath(可以形成环形线圈)AngIeOftwist:OdegDraftAngle:OdegDrafttyPe:ROUnd次级绕组MOdeIer>GridPIane>YZDraW>ReCtanglePOSition：(0,,)BOX尺寸：(XSiZe,YSize,ZSiZe)>(0,2,15)MOdeIer>GridPIane>XYDraW>ReCtanglePosition：(,,13)BOX尺寸：(XSiZe,YSize,ZSiZe)>(15,15,0)选中ReCtangIe4MOdeIer>DeIeteLaStOPeration选中ReCtangle3,ReCtangIe4DraW>SWeeP>AIOngPathAngIeOftwist:OdegDraftAngle:OdegDrafttyPe:ROUnd将ReCtangIe2和ReCtangIe4重命名为：COiI_in,COiI_OUt将所有COil的材料改为COPPer创建激励电流加载而(CreateSeCtiOn)选中所有线圈MOdeIer>SUrfaCe>SeCtiOn选中YZ平而MOdeIer>BOOIean>SeParateBOdieSEdit>DeIete(删除多余的面)将生成的截而重命名为：Sectionl,SeCtiOn2创建计算区域(RegiOn)DraW>RegiOnRegiOnPaddingData;厂PadalldirectionsSimiIarIyQPadindividualdirections「TranSVerSePaddingDireCtiOnPaddingtypeValUeUnitS十XPerCentagEOffSet15-XPerCentageOffcet15+YPerCentagmOffSet30-YPerCentag亡OffSet30+zPerCentageOffSet30-ZPerCentageOffeet30厂SaVeasdefe□ltOK]CanCel设置激励(ASSignEXCitatiOn)选中内层线圈截而：SeCtiOnIMaXWelI3D>EXCitations>ASSign>CUrrentName:ChUjiVaIUe:IOAType:Stranded选外层线圈截面：SeCtiOn2MaXWelI3D>EXCitatiOnS>ASSign>CUrrentName:次级Value:15ATyPe:Stranded设置自适应计算参数(CreateAnaIySiSSetUP)MaXWelI3D>AnaIySiSSetUP>AddSOIUtiOnSetUP最大迭代次数：MaXimUmnumberOfPaSSeS:10误差要求：PerCentErrOr:1%每次迭代加密剖分单元比例：RefinementPerPaSS:30%设置非线性残差：nonlinearresidual:设置计算参数(ASSignEXeCUtiVeParameter)MaXWelI>ParameterS>ASSign>Matrix弹出MatriX窗口在SetUP子菜单下，include栏中确认打钩在PoStPrOCeSSing子菜单下，TUrnS栏中初级对应的改为30TUrrIS栏中次级对应的改为300设置参数FOrCeMaXWelI>ParameterS>ASSign>FOrCe点击0K。网格剖分的话，由于模型简单，用软件自己剖分就好了。5.CheCk&RUnValidatiOnCheck;transformer-MaXxVell3DD^signl彰夕MaXWeIl3DDesignlVaIidationCheCkCOrnPleted.MDeSignSettingS&3DMOdelMBOUndarieSandEXCitatiOnS&ParametersSMeshOperationsMAnalysisSetupOPtir∩ξ≡Uic?AbOrtICIOSeClozse6.查看结果MaXWelI3D∕result∕SOIUtiOndata线圈受力。SOIUtions;transformer-Maκ√rell3DDesignlSirdation:习ILd^XjCeZi/cjDCJianVanetiCnFrOfiICICcr4VcrgancoFOrCe∣TOrqUa∣Witrικ∣HxhStallZtLc:]Parameter:IForCCl三∣FOlCeUntIeAtOn▼]EKDDlISOIUliOn...]Pθ55.CloSe电感信息*SOlUtiOn5：transformer-MdXWell3DDesIgnlSmulatiorrISetUPl▼|ILaWV%daptN6JdDcsbiVefidixcMatrhInStatistics]TrOfiIe|COnVereenCe∣POrCe∣IoraUePaameter:fΛ⅛(tx1ΞJΓ⅛wIIndUCtcrCeΞJIndUe必CQUni麼E冲or⅜Solulion,|EXPOItCrCUt…IΓPosiPgccsccd3命令，可以图形显示选中物体，执行MaXZ31)ZFleIdSzPIOtIne选中物体，执行MaZ3D∕Fields∕F3ds∕B,选中ObJeCt,点、6.W77E-β016.3S39E-^01s.W0ie-^θi3.>⅝G3t-αeιH.M25e-^θ∣M.5386E-^01Mθe⅛ΘE^3013.63IeE-QeI3.P72E-^01I2.723*EYDlI2.269βε-^θlaIBiREq01I13619E-GelI908IIE-«02IW29Z02■MnI6E-«aS
