摘要
在A -V位和库仑规范的前提下 ,导出了三维涡流区域微分方程和自由空间积分方程在涡流区边界上的耦合条件。在此基础上 ,提出了A -V位的三维涡流场FE—BE耦合分析方法。对国际TEAM 2 1号问题B模型进行了计算 ,靠近线圈的钢板表面磁感应强度法向分量计算值与实测值基本一致。
The coupling conditions between eddy current region and free space in 3-D eddy current problems are derived in potential A-V with the Coulomb's gauge.Based on these conditions, a new FE-BE analysis method is proposed.This new method has been used to compute the model B of TEAM workshop problem 21.The computed results of the normal component magnetic flux density near the surface of the steel plate approach to the measured results.The distribution of eddy currents in the steel plate is reasonable.
