| 摘 要： | 介绍了采用将数值与解析联合起来计算矩形导电媒质涡流损耗的方法。首先利用积分方程法求出磁介质表面网格点的入射磁密，然后对这些任意分布的离散磁密点用双重傅立叶级数进行逼近，最后计算涡流损耗。通过验证，计算值与测量值吻合很好，证明了该方法的可行性。

| Abstract: | A hybrid method is developed for calculating eddy current losses of a thin steel plate. The incident flux of net points on the upper face of a steel plate is determined by a integral equation and a curve fit to a double Fourier series is obtained. The method has been applied to TEAM Problem 21(Model B). Agreement of calculated values with test results shows the validity of the method of calculation presented. |
