摘　　要：提出用有限元法及相似原理来分析、计算磁悬浮球的悬浮系统。对系统中的永磁体,采用了等效电流模型。用MATLAB偏微分方程工具箱分析了悬浮系统的磁场,计算了磁场的引力;引力的计算值与实测值的一般误差不超过5%。An analysis and calculation of the suspension system of maglev ball by finite element method(FEM) and similarity principle is presented.As for the permanent magnet in the system,the(equivalent) current model is adopted.A magnetic field is analyzed and the magnetic pull is computed with MATLAB PDE toolbox.The pull's computed values are fully consistent with the measured values.
