摘要
为使超磁致伸缩驱动微泵中超磁致伸缩材料(GMM)棒获得最佳的磁致伸缩性能,在ANSYS Maxwell软件中建立双线圈式驱动磁场、外线圈内永磁体式驱动磁场、内线圈外永磁体式驱动磁场模型,进行仿真分析,得到三种情况下微泵轴线上平均磁场强度和磁场均匀度,并通过试验验证优选结构的磁场强度和均匀度。结果表明:外线圈长度L_(q1)=104 mm,厚度d_(q1)=12.5 mm;内线圈长度L_(q2)=104 mm,厚度d_(q2)=12.5 mm的双线圈式驱动磁场相对于外线圈内永磁体式和内线圈外永磁体式平均磁场强度提高了117%和8.6%,磁场均匀度下降4%。试验结果与仿真结果基本吻合,验证了仿真模型的正确性。
In order to make the GMM rod in giant magnetostrictive driving micro pump get the best magnetostrictive scalability,model of double coil type cylinder driving magnetic field,external coil & internal permanent magnet type cylinder driving magnetic field and internal coil & external permanent magnet type cylinder driving magnetic field in ANSYS respectively were set up,then gotten three kinds of micro pump axis average magnetic field intensity and magnetic field uniformity by simulation analysis. Finally the magnetic field intensity and evenness of optimized structure by experiment were verified. The result shows that the double coil type cylinder driving magnetic field with external coil L_(q1)= 104 mm,thickness d_(q1)= 12. 5 mm,internal coil L_(q1)= 104 mm,thickness d_(q1)= 12.5 mm increases 117% and 8.6% average magnetic field intensity,more than external coil &internal permanent magnet type cylinder driving magnetic field and external permanent magnet & internal coil type cylinder driving magnetic field. However,the uniformity decline was 4%. The experimental result in line with simulation result verifies the rationality of the simulation model.
