摘　　要：在介绍无网格迦辽金法(Element-Free Galerkin Method,EFGM)基本原理的基础上,采用EFGM建立了应用A-φ-A法表示的谐波电磁场控制方程在圆柱坐标系下的通用三维离散模型.针对一轴向磁通感应加热电磁场问题,对其进行了EFGM离散模型和算法的数值实现,其计算结果与采用FEM所得到的结果吻合良好,表明EFGM离散模型和数值算法的正确性.Based on the element-free Galerkin method （EFGM）, the general discrete 3D model of A-φ-A govern equations of harmonic electromagnetic field was achieved in cylindrical coordinates. As an applica- tion example, the electromagnetic field of an axial flux induction heating was studied by using the EFGM, and the computation results agree with the results of the FEM. It proves that the EFGM discrete model and numerical algorithm are reasonable.
