用maxwell对变压器的建模仿真教程

该变压器模型采用EE^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。.建模（Model）Project>InsertMaxwell3DDesignFile>Saveas>transformer选择求解器类型：Maxwell>SolutionType>Magnetostatic创建变压器铁芯框架Draw>BoxPosition：(-5.5,-15,0)Box尺寸:(XSize,YSize,ZSize)>(11,30,26)Draw>BoxPosition：(-5.5,5.5,5)Box尺寸:(XSize,YSize,ZSize)>(11,4.5,16)选中Box2Edit>Duplicate>AroundAxisAxis:ZAngle:180degTotalnumber:2选中Box1,Box2,Box2_1Modeler>Boolean>SubtractBlankParts:Box1ToolParts:Box2，Box2_1不要选：“Clonetoolobjectsbeforesubtracting)Draw>Box(创建Gap(缺口))Position：(-5.5,15,12.98)Box尺寸：(XSize,YSize,ZSize)>(11,30,0.04)选中Box1,Box3Modeler>Boolean>SubtractBlankParts:Box1ToolParts:Box3不要选：“Clonetoolobjectsbeforesubtracting)选中Box1Modeler>Boolean>SeparateBodies将分离后的模型分别重命名为："Core_up"(原Box1)和“Core_down”将两者的材料重设为：“ferrite”为铁氧体的材料属性。创建线圈初级绕组Modeler>GridPlane>YZDraw>RectanglePosition：(0,6,5.5)Box尺寸：(XSize,YSize,ZSize)>(0,1,15)Modeler>GridPlane>XYDraw>RectanglePosition：(-6,-6,13)Box尺寸：(XSize,YSize,ZSize)>(12,12,0)选中Rectangle2Modeler>DeleteLastOperation(形成Rectangle1围绕的轨迹)选中Rectangle]Rectangle2Draw>Sweep>AlongPath(可以形成环形线圈)Angleoftwist:0degDraftAngle:0degDrafttype:Round次级绕组Modeler>GridPlane>YZDraw>RectanglePosition：(0,7.5,5.5)Box尺寸：(XSize,YSize,ZSize)>(0,2,15)Modeler>GridPlane>XYDraw>RectanglePosition：(-7.5,75,13)Box尺寸：(XSize,YSize,ZSize)>(15,15,0)选中Rectangle4Modeler>DeleteLastOperation选中Rectangle3,Rectangle4Draw>Sweep>AlongPathAngleoftwist:0degDraftAngle:0degDrafttype:Round将Rectangle环口Rectangle41t命名为：Coil_in,Coil_out将所有Coil的材料改为Copper创建激励电流加载面(CreateSectior)选中所有线圈Modeler>Surface>Section选中YZ平面Modeler>Boolean>SeparateBodiesEdit>Delete（删除多余的面）将生成的截面重命名为：Sectionl,Section2创建计算区域（Region）Draw>Region.设置激励（AssignExcitation）选中内层线圈截面：SectionlMaxwell3D>Excitations>Assign>CurrentName:chujiValue:10AType:Stranded选外层线圈截面：Section2Maxwell3D>Excitations>Assign>CurrentName:次级Value:15AType:Stranded.设置自适应计算参数(CreateAnalysisSetupMaxwell3D>AnalysisSetup>AddSolutionSetup最大迭代次数：Maximumnumberofpasses:10误差：PercentError:1%每次迭代加密剖分单元比例：RefinementperPass:30%设置非线性残差：nonlinearresidual:0.001.设置计算参数(AssignExecutiveParameterMaxwell>Parameters>Assign>Matrix弹出Matrix窗口在Setup?菜单下，include栏中确认打钩在PostProcessings菜单下，Turns栏中初级对应的改为30Turns栏中次级对应的改为300设置参数ForceMaxwell>Parameters>Assign>Force点击OK。网格剖分的话，由于模型简单，用软件自己剖分就好了。.Check&Run.查看结果Maxwell3D/result/solutiondata线圈受力。电感信息■Solutions;transformrr-MsH3Dsign1grsulaionpetupl1]fLa汕+倒心工|DssiamVcjdtcn;Irafllt|Ccwrg.nm|Foret|TorwtNiiria|vi*lhSttlisties|ngESjer.M才能1TvpsOnduztancBUrit&:卜岫。纲匕厂E?wiSol诵［出:|hpoit匚叱训一「PDJlPlCCCJiCd[Curmll|二unmtiCurtnfl11B171177.5Cunnt?im»IISI压器模型剖分情况。/—一，一，yr』K「;■选中物体，执行Maxwell3D/Fields/Fields/B,-留6.BEiTTE-ML彳|E.353-^-0315glimMBiE二丁Jj/\J■1—/1//\J「选中Object,点击DonejrB7」>犀——/选中物体，执行Maxwell3D/Fields/Plotmesh命令，可以图形显示变
