摘　　要：磁流体动力钎焊设备主要用于电机换向器绕组线圈的焊接,焊接过程中电磁场的状态很难测定,采用边棱元法对其焊接过程进行3D数值模拟分析。数值模拟过程和结果能与实际结果达到很高精度的匹配。边棱元3D数值模拟方法可以成功应用在复杂几何形状的设备和非线性特性材料的电磁过程研究。The electromagnetic field state of MHD welding process is difficult to determine. 3D numerical analysis of the electromagnetic field in a magneto-hydro dynamic device for soldering the winding to the commutator of electric machines was carried out by means of the edge element method. The very good convergence of numerical process and the accuracy of the obtained results show that the edge element method is suitable for studying the electromagnetic processes in devices with complex geometry and non-linear properties of materials.
