摘要
采用双重傅里叶级数对任意形状薄钢板表面法向磁密进行逼近，待定系数用遗传算法结合Ｐｏｗｅｌ优化法确定，然后用解析公式计算涡流分布及损耗大小。最后对ＴＥＡＭＰｒｏｂｌｅｍ２１（ＭｏｄｅｌＢ）进行了计算，并与测量值比较，吻合很好。
The incident flux on the upper face of steel plate of arbitrarily shape is fit by a double Fourier series.The unknown coefficients are determined by the genetic algorithm and Powell method.It is applied to TEAM Problem 21(Mode B).Agreement of calculated values with test results shows the validity of the method of calculation presented.
