摘要

提出了一种有效的三维瞬态有限元方法，用于计算磁性转子在铝板导轨上平动和旋转时产生的升力、推力和侧向力。转子磁场由一个等效的虚拟磁荷片公式计算。通过将场项纳入导轨边界条件来考虑转子场对导轨的影响。通过与稳态实验和有限元计算的比较，验证了该模型的正确性。

Three dimensional transient modeling of a halbach rotor moving above a conductive guideway using fictitious magnetic charge

An efficient three-dimensional transient finite element method for calculating the lift, thrust and lateral forces created when a magnetic rotor is both translationally moved and rotated above an aluminum sheet guideway is presented. The rotor field is calculated from an equivalent fictitious magnetic charge sheet formula. The rotor field's effect on the guideway is accounted for by incorporating the field terms into the guideway boundary conditions. This model is validated by comparing it with steady-state experimental and finite element calculations.
