ansys分析电磁场

1三维螺线管静态磁场分析要求计算螺线管，如下图所示，衔铁所受磁力，线圈为直流激励，产生力驱动衔铁。线圈电流为6A，500匝。由于对称性，只分析1/4的模型，如图1所示：图1螺线管制动器在仿真分析时，空气相对磁导系数为1.0；使用智能网格划分（LVL=8）；设定全部面为通量平行，这是自然边界条件，自动得到满足。因为是采用的1/4对称模型，所以磁力的计算结果要乘以4。2施加边界条件：!/SOLUD,2,MAG,0!!SOLVE!ALLSEL,ALLMAGSOLV,3,,,,,1FINISH!建立的模型如下图所示：3对模型进行智能网格划分，如下图所示：仿真分析所得磁场强度分布图为：4衔铁所受磁力分布图为：衔铁所受磁力分布图为：56计算所得衔铁所受磁力为：SUMMARYOFFORCESBYVIRTUALWORKLoadStepNumber:2.SubstepNumber:1.Time:0.2000E+01UnitsofForce:(N)ComponentForce-XForce-YForce-ZARM0.14339E+020.11359E+02-0.12846E+02___________________________________________________SUMMARYOFFORCESBYMAXWELLSTRESSTENSORUnitsofForce:(N)ComponentForce-XForce-YForce-ZARM0.79007E+010.55769E+01-0.11511E+02_____________________________________________________Note:MaxwellforcesareintheGlobalCartesiancoordinatesystem.VirtualworkforcesareintheelementESYScoordinatesystem.7ThefollowingelementtableitemsareavailableforprintingandplottingoftheforcesobtainedbyVirtualWorkandtheMaxwellStressTensormethods.ElementItemNameMethodDirectionFVW_XVirtualWorkXFMX_XMaxwellStressXFVW_YVirtualWorkYFMX_YMaxwellStressYFVW_ZVirtualWorkZFMX_ZMaxwellStressZ___________________________________________________________________本题采用输入命令流的方法处理，命令流如下：!/BACH,LIST/TITLE,3-DSTATICFORCEPROBLEM-TETRAHEDRAL!定义工作标题/FILNAME,EMAGE_3D,1!定义工作文件名KEYW,MAGNOD,1!指定磁场分析/PREP7!定义分析参数N=500!线圈匝数I=6!每匝通过的电流!定义单元类型ET,1,96!给空气和衔铁定义材料属性MP,MURX,1,1TB,BH,2,,40TBPT,,355,0.7,,405,0.8,,470,0.9,,555,1.0,,673,1.1,,836,1.2,,1065,1.3,,1220,1.35,,1420,1.4,,1720,1.45,,2130,1.5,,2670,1.55,,3480,1.68,,4500,1.65,,5950,1.7,,7650,1.75,,10100,1.8,,13000,1.85,,15900,1.9,,21100,1.95,,26300,2.0,,32900,2.05,,42700,2.1,,61700,2.15,,84300,2.2,,110000,2.25,,135000,2.3,,200000,2.41,,400000,2.69,,800000,3.22TBCOPY,BH,2,3!创建电极体/PNUM,VOLU,1BLOCK,0,63.5,0,25/2,0,25/VIEW,1,1,1,1/REPLOTBLOCK,38.5,63.5,0,25/2,25,125BLOCK,13.5,63.5,0,25/2,125,150VGLUE,ALL!创建衔铁、空气体并压缩编号BLOCK,0,12.5,0,5,26.5,125!衔铁体BLOCK,0,13,0,5.5,26,125.5!空气体VOVLAP,1,2NUMCMP,VOLUCYL4,,,0,0,100,90,175VOVLAP,ALLNUMCMP,VOLU!设置几何体的属性VSEL,S,VOLU,,1VATT,3,1,1!设置衔铁属性VSEL,S,VOLU,,3,5VATT,2,1,1!设置电极属性!给模型划分网格ALLSEL,ALLSMRT,8!定义网格智能划分等级为8MSHAPE,1,3DMSHKEY,09VMESH,ALL/PNUM,MAT,1/NUMBER,1EPLOT!!把衔铁定义成一个组件并施加力标志!ESEL,S,MAT,,3!选择衔铁材料单元CM,ARM,ELEMFMAGBC,'ARM'!!转换模型单位制为米!ALLSEL,ALLVLSCALE,ALL,,,0.001,0.001,0.001,,0,1!!创建线圈!LOCAL,12,0,0,0,75/1000WPCSYS,-1,12RACE,0.0285,0.0285,0.014,N*I,0.018,0.0966,,,'COIL1'/ESHAPE,1EPLOTSAVEFINISH!!施加边界条件!/SOLUD,2,MAG,0!!SOLVE!ALLSEL,ALLMAGSOLV,3,,,,,1FINISH!!对衔铁受力求和!/SOLU*DIM,CUR,ARRAY,1CUR(1)=ILMATRIX,1,'COIL','CUR'FINISH
