摘要
基于超磁致伸缩材料的工作原理,设计了具有微位移可控特性的驱动器。为了探究驱动器内部磁场设计的合理性以及超磁致伸缩驱动器的磁感应强度与激励电流之间的关系,应用ANSYS有限元分析软件对超磁致伸缩驱动器的内部磁场进行仿真。研究结果表明,超磁致伸缩驱动器磁场设计合理;随着电流的增大,超磁致伸缩材料中的磁感应强度也随之增加并且磁感应强度逐渐趋于饱和。
Based on the principle of giant magnetostrictive materials(GMM),the internal magnetic field of actuator was designed.In order to explore the rationality of magnetic field design and the relationship between magnetic induction intensity and excitation current of giant magnetostrictive actuator,the internal magnetic field of giant magnetostrictive actuator was simulated by ANSYS finite element analysis software.The results showed that the magnetic field design of the giant magnetostrictive actuator was reasonable,and the magnetic induction intensity in the giant magnetostrictive material increased with the increase of the current,and the magnetic induction intensity of the giant magnetostrictive material tended to saturation gradually.
