Analysis on Magnetic Field Distribution of Giant Magnetostrictive Actuator Based on a Displacement Transmission Mechanism

  • 摘要: 为放大超磁致伸缩致动器的位移,设计了位移传递机构以叠加致动器中超磁致伸缩棒和筒的输出。针对该致动器中棒和筒的磁场分布问题,基于有限元法建立了磁场强度的计算电磁学模型,并利用ANSYS软件进行了仿真。通过仿真得到了棒和筒上任一点磁场强度,并基于一种新的平均化方法确定了截面磁场强度平均值;最后得到位移传递机构取不同磁导率时棒和筒上磁场强度的轴向分布规律。
