用修正的T-Ω方法计算考虑铁磁材料非线性、磁滞影响的三维涡流场

The New Application of Modified T-Ω Method to the Computation of 3D Eddy Current Problems

对过去提出的三维涡流场计算的修正T一Ω模型进行了进一步分析讨论,着重考虑了铁磁材料的非线性磁滞影响.本文提出的思想方法在实例中得到了应用,并分别比较了计算结果.

Based on the preceding modified T-Ω model in the calculation of 3D eddy current problems, some further analyses and discussions have been made while more emphases are paid on the. treatment of nonlinearity and hysteresis of ferromagnetic materials in 3D eddy current problems. The method and idea developed in the paper arc applied to two examples. The computation results are compared with those in other references and with experimental ones respectively.
