摘要

讨论了考虑涡流的电磁场建模问题。提出了一种计算总矢量磁势和约标量磁势耦合涡流的公式。采用有限元法近似总矢量磁势，采用边界元法近似约简标量磁势。研究了该方法的有效性，并与纯有限元法进行了比较。这些结果是通过解决涡流对磁体活化影响的计算问题而得到的。

Coupled vector FEM and scalar BEM formulation for eddy current problems

A problem of electromagnetic field modeling with consideration of eddy currents is addressed. A formulation for calculating eddy currents with coupled total vector magnetic potential and reduced scalar magnetic potential is presented. The finite element method (FEM) is used to approximate the total vector magnetic potential and the boundary element method (BEM) is used to approximate reduced scalar magnetic potential. The efficiency of the proposed method is investigated and compared to the pure FEM formulation. The results are obtained by solving the problem of calculating the effect of eddy currents on a magnet activation.
