摘要 基于Preisach磁滞模型,提出了面向非对称磁滞回线模拟的参数辨识方法,并应用于取向硅钢片的静态及动态磁滞特性模拟。通过实验获得取向硅钢片静态直流偏磁极限磁滞回线, 利用数值方法生成具有非对称特征的一阶回转曲线,进而建立直流偏磁条件下的Everett函数。对静态下的直流偏磁磁滞回线进行拟合,通过与实验结果的对比,验证了该文方法的有效性。进一步考虑直流偏磁磁场和交流磁通密度峰值对异常损耗的影响,构建直流偏磁动态磁滞模型,实现了直流偏磁条件下取向硅钢片损耗特性的模拟,分析了直流偏磁对不同类型损耗的影响。

Abstract:Based on the Preisach model, a parameter identification method for simulating asymmetric hysteresis loops is proposed and applied to the simulation of static and dynamic hysteresis characteristics of grain-oriented (GO) silicon steel sheet. Due to the asymmetry of curves under the DC bias, an algorithm was presented to create asymmetrical first order reversal curves (FORCs) according to the experimental data of major hysteresis loop measured in DC-bias condition, and the corresponding Everett function was established. The static hysteresis curves were simulated by the Preisach model. The consistency between the simulated results and the measured ones verified the proposed method. Finally, the DC-biasing dynamic hysteresis model was constructed considering the influence of DC bias magnetic field and AC magnetic flux peak on excess loss. In addition, the loss characteristics of GO silicon steel sheet under DC bias condition were simulated. The influence of DC bias on different types of losses was analyzed.
