ansys分析电磁场

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:07S mrm*1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。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:1对模型进行智能网格划分，如下图所示:3#EXEMEKESMAI JTOM!漁氫篦宸卡縣螺回3-D STATIC FORCE PROBLEM 一 TETRAHEDRALANSYSMAY 27 201S16:58:17ANSYSMAY 27 201518:54:52仿真分析所得磁场强度分布图为:VECI0RSUB >1TIME=2 HELE19798MIN-30*7S15MAX.13E+07#30-7S1S3017S10347190S!91.121E+07isoeai4&2«117S4331-106E+07,136E+073«D STATIC FORCE PROBLEM = TETRAHEDRAL!氫篦宸卡 縣鎳0#衔铁所受磁力分布图为:#ANSYS1 VECTORMAY 27 20151E:57:3OSUB -1TIME=2EHAGELEM=438eHIN-0HAX-.«313S23-D STATIC FORCE PROBLEM - TETRAHEDRAL1011 ,21017280A23.421234.351029"91 钳.631852-瀚氫直宸錢螺團#衔铁所受磁力分布图为:#1NODAL SOLUTIONSUB -1TIME=2ANSYSMAY 27 2015 1S：59;33EHAGX(AVG|RSY5=QSUN .769E-033MK -.939865-.?e»E-08.aoBKi.»ea2i.aa»asiP103744niiane.sieoe.?9db»3-D STATIC FORCE PROBLEM - TETRAHEDRAL!繪适篦宸卡萤踝|3#5NODAL SOLUTIONSUB =1TIME=2EMAGY (AVG) RSYSOSMN =-.004737SMX =.338854ANSYSMAY 27 201519:00:05#004737-07117.14797.224324_300677.186147.2625-330054.03344.1097933-D STATIC FORCE PROBLEM 一 TETRAHEDRAL#1NODAL S0LU7I0NSUB =1TIME=2FMAGZ (AVG)RSYSOSMN =-l»31609SMK =.46632ANSYSMAY 27 201519:00:39#-1-3109一.919999-52390S-.127817_266274一.32E862.070229!滴氫篦宸卡縣鐸回-1.11B04-.7219533-D STATIC FORCE PROBLEM - TETRAHEDRAL#NODAL SOLUITONSUB -1TIHE=2EHAGSOH (KVG)R5YS=a5HXANSYSMAY 27 201519:01:560.29246SSB493*3773951.16986.146232.4386977311621,023631.316093-D STATIC FORCE PROBLEM - TETRAHEDRAL!氫篦宸¥我螺9#计算所得衔铁所受磁力为:SUMMARY OF FORCES BY VIRTUAL WORKLoad Step Number:2.Substep Number:1.Time:0.2000E+01Un its of Force:(N )Comp onentForce-XForce-YForce-ZARM0.14339E+020.11359E+02-0.12846E+02SUMMARY OF FORCES BY MAXWELL STRESS TENSORUnits of Force: ( N )Comp onentForce-XForce-YForce-ZARM0.79007E+010.55769E+01-0.11511E+02Note: Maxwell forces are in the Global Cartesia n coord in ate system.Virtual work forces are in the eleme nt ESYS coord in ate system.The following element table items are available for printing and plotti ng of the forces obta ined by Virtual Work and the Maxwell StressTen sor methods.Eleme nt Item NameMethodDirectionFVW_XVirtual WorkXFMX_XMaxwell StressXFVW_YVirtual WorkYFMX_YMaxwell StressYFVW_ZVirtual WorkZFMX ZMaxwell StressZ本题采用输入命令流的方法处理，命令流如下:!/BAC H,L IST定义工作标题定义工作文件名!指定磁场分析/TITLE,3-D STATIC FORCE PROBLEM - TETRAHEDRAL /FILNAME,EMAGE_3D,1KEYW,MAGN0D,1/PREP7!定义分析参数N=500!线圈匝数1=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,355,0.7,405,0.8,470,0.9,555,1.0,673,1.1,836,1.2,1065,1.3,1220,1.35,1420,1.4,1720,1.45,2130,1.5,2670,1.55,3480,1.67,4500,1.65,5950,1.7,7650,1.75,10100,1.8,13000,1.85,15900,1.9,21100,1.95,26300,2.0,32900,2.05,42700,2.1,61700,2.15,84300,2.2,110000,2.25,135000,2.3,200000,2.41,400000,2.69,800000,3.22TBCOPY,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,13.5,63.5,0,25/2,125,150衔铁体 空气体! 设置衔铁属性! 设置电极属性VGLUE,ALL !创建衔铁、空气体并压缩编号 BLOCK,0,12.5,0,5,26.5,125 BLOCK,0,13,0,5.5,26,125.5VOVLAP,1,2NUMCMP,VOLUCYL4,0,0,100,90,175VOVLAP,ALLNUMCMP,VOLU!设置几何体的属性VSEL,S,VOLU,1VATT,3,1,1VSEL,S,VOLU,3,5VATT,2,1,1 !给模型划分网格ALLSEL,ALLSMRT,8 ! 定义网格智能划分等级为MSHAPE,1,3DMSHKEY ,0VMESH,ALL/PNUM,MAT,1/NUMBER,1EPLOT!把衔铁定义成一个组件并施加力标志!ESEL,S,MA T,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'FINISH9
