摘　　要：针对电动车用双凸极永磁电动机运用有限元法进行计算时对各个点的磁场的特殊要求,采用改进的三角网自动生成算法,使其能对各个区域的三角形的疏密灵活地进行控制,并采用独立的三角形所在的区域判断和边界判断法。剖分实例显示,该方法能生成高质量的网格,适应能力强,并已成功应用于车用外转子双凸极永磁电动机的有限元计算,取得了良好的效果。Facing the particular needs of each pole＇s magnet on the calculating in finite element for doubly salient permanent magnet machine for electric vehicle, developed a fully automation Triangle mesh generation methods, Taking the methods of the regional and border judgment of triangle independently. The results showed that it was a capable of adaptively generating meshes with resonable quality. It had been successfully applied to the calculating in finite element of the external rotor double salient permanent magnet machine in vehicle.
