| 摘 要： | 提出双标量磁位的表面阻杭法，以计算含有钢板的三维磁场分布和钢板涡流损耗。文中在钢板周围采用全标量磁位处理阻抗边界条件，而在源电流区域采用简化标量磁位，并应用磁余能量方法，引入等效虚拟磁性材料处理钢板的非线性问题。将本方法应用于ＴＥＡＭ问题２１模型，计算结果与实测结果相吻合。

| Abstract: | A surface impedance method using two scalar magnetic potentials has been presented to compute the distribution of 3D magnetic field and eddy current losses of steel plate. In this method,a totoal scalar magnetic potential is used to deal with the impendance boudary condition, and a reduced scalar magnetic potential is used in current region. The nonlinear problem is solved by using a fictitious magnetic material that is obtained by the magnetic co-energy in steel plate. The TEAM problem 21 has been calculated by this method and the computational results coincide with the measured values. |
