Calculations of Hysteresis Loop Model Parameters for Magnetic Materials

为了在磁开关数值模拟中采用Jiles Atherton模型描述磁性材料的磁滞特性,本文推导出一组计算公式,由实验得到的磁滞回线中的8个特征参数,通过计算确定Jiles Atherton模型中的5个模型参数,并应用一个具体实例对该方法的准确性进行了验证。

In order to use Jiles-Atherton model for the hysteresis characteristics of magnetic materials in numerical simulations of magnetic switches, a computational method was developed to determine 5 model parameters in the Jiles-Atherton model from 8 characteristic parameters of hysteresis loop obtained by experimental measurements. An applied example was used to show the validity of the method.
