提出一种3自由度等刚度永磁弹簧。该永磁弹簧由3组环形永磁体和柱形永磁体均匀对称布置构成。根据永磁弹簧的结构，改变永磁弹簧参数进行有限元分析，对径向磁力进行仿真计算。仿真结果表明，随着永磁弹簧的永磁体牌号、柱形永磁体的半径和长度、环形永磁体的长度的增加，弹簧径向磁力增加。随着环形永磁体的平均半径的增加，弹簧径向磁力减小。随着环形永磁体和柱形永磁体间的竖直方向气隙长度的增加，弹簧径向磁力呈抛物线趋势变化。实验验证结果和仿真计算结果基本吻合。

This paper proposes a 3 DOF same stiffness permanent magnetic spring. This permanent magnetic spring consists of 3 pairs of annular permanent magnets and cylindrical permanent magnets which are ar-ranged uniformly and symmetrically. According to the structure of permanent magnetic spring, the simula-tion radial magnetic force is carried out by finite element method by changing size parameters. The simula-tion results show that radial magnetic force increases with the increasing of permanent magnetic type, the ra-dius and axial length of cylindrical permanent magnet and the axial length of annular permanent magnet. The radial magnetic force decreases with the increasing of the averaged radius of annular permanent magnet. The radial magnetic force changes in parabolic trend along with the increasing of air gap length between annular permanent magnet and cylindrical permanent magnet. The simulation results are basically in agreement with the experimental results.
