基于Maxwell的仿生电磁鱼鳍有限元分析
Finite Element Analysis of Bionic Electromagnetic Fish Fin Based on Maxwell
摘要: 电磁驱动器是一种利用电磁力进行运动控制的装置，通过电流在线圈中产生的磁场与永磁体或其他铁磁材料相互作用，实现精确的力和运动控制。本文利用SolidWorks建立一种仿生单线圈磁驱动鱼鳍的三维模型，并将模型导入Maxwell中进行静磁场和瞬态电磁场分析。静磁场分析结果表明线圈产生的最大磁场强度为22.2 mTesla，磁场呈轴对称分布。瞬态电磁场分析得出了不同激励下的磁力扭矩和空间角度关系，随激励电流的增加，扭矩力随着电流线性增大。
Abstract: An electromagnetic actuator is a device that uses electromagnetic force for motion control, and the magnetic field generated in the coil through an electric current interacts with a permanent magnet or other ferromagnetic material to achieve precise force and motion control. In this paper, a three-dimensional model of a bionic single-coil magnetically driven fish fin is built by SolidWorks, and the model is imported into Maxwell for static magnetic field and transient electromagnetic field strength generated by the coil is 22.2 mTesla, and the magnetic field is axisymmetrically distributed. The transient electromagnetic field analysis obtains the relationship between the magnetic torque and the spatial angle under different excitations, and the torque force increases linearly with the increase of the excitation current.
