摘　　要：以常见的螺线管致动器为例,简述了磁路法计算电磁参数时对铁磁材料特性的处理方法及其局限性。将铁磁材料设定为线性和非线性磁导率,采用磁场数值模拟分别计算了磁场参数。通过对计算结果的对比分析,定量讨论了对铁心赋予不同材料特性条件下磁场设计参数所受的影响。Taking a common solenoid actuator for an example, different treating ways to deal with material property and their disadvantages in calculation of magnetic circuit are briefly described in this paper. With focus on the material character, simulation method is utilized for the same actuator model, and magnetic parameters are obtained with stator and armature endowed with linear magnetic permeability and real B-H curve, respectively. By comparing and analyzing the calculating results, effects of material character on the field distribution are quantitatively displayed.
