摘要: 为描述旋转磁化过程并有效模拟各向异性对于磁化过程的影响,在矢量磁滞算子模型(vector hysteron model,VHM)的框架下改变了基于等势面模拟磁化过程的方法,提出了一种新的磁滞算子实现方法。采用分支曲线作为磁滞算子临界面方程,并利用有向分支曲线的方法对算子的临界面方程进行求解。为了能够进一步研究模型在不同激励条件下的精确模拟,对不同频率下的实验数据进行了参数辨识,并采用Moving函数对辨识参数的分布进行了表征。通过模拟计算结果与实验数据的对比,验证了新型矢量磁滞模型的有效性。

Abstract: A novel implementation of a hysteresis operator in the framework of Vector Hysteron Model (VHM) is presented to describe rotational magnetization. In order to simulate the effect of anisotropy on the magnetization process more effectively, this paper changes the method of using the equipotential surface to simulate the magnetization process in the VHM model, and discusses a new scheme. This model uses the bifurcation curve as the critical surface equation of the hysteron, and uses the method of the directed bifurcation curve to solve the hysteron's critical surface equation. To further discuss the simulation performance of the model under different excitations, this paper identifies the experimental data at different frequencies, and the Moving functions are used to describe the identified parameters. The comparison between simulation results and the experimental data has been given hereafter and it is shown that the new approach is acceptable and shows good effectiveness.
