摘　　要：针对电动车用电励磁双凸极电机运用有限元法进行计算时对各个点的磁场的特殊要求,基于Delaunay算法,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和角度变化灵活的进行控制。通过剖分实例显示,该方法能生成高质量的网格,适应能力强,已成功地应用于车用外转子电励磁双凸极电机的有限元计算,并取得了良好的效果。Facing the particular needs of each pole＇s magnet on the calculating in finite element for doubly salient electro-magnetic motor for electric vehicle. Used the improved triangulation automatically generating algorithm, control the density and angle-changing of the triangle in various regions freely at the base of Delaunay＇s algorithm. The results show that it is a capable of adaptively generating meshes with reasonable quality. It has been applied to the calculating in finite element of the external rotor doubly salient electro-magnetic motor in vehicle.
