摘要
针对电动车用双凸极永磁电机运用有限元法进行计算时对各个点磁场的特殊要求,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,它已成功的应用于车用外转子双凸极永磁电机的有限元计算,并取得了良好的效果。
Facing the special requirements on finite-element calculation of magnetic field at various points,an improved automatically-generated triangulation net algorithm is used for electric vehicle doubly-salient PM motor to control the density and angles of the triangles in all regions flexibly.The dissection examples show that this method can generate high-quality dissection net and strong adaptability,it has been successfully applied to finite-element calculation for the external rotor doubly-salient PM motor and has achieved good effect.
