摘要

建立了铁磁介质中标量迟滞的数学模型。该模型基于复磁导率的概念，包括Fröhlich函数等解析表达式。采用Preisach滞回模型获得复磁导率的初始数据。阐述了该算法考虑谐波平衡法中的滞后现象的特点。通过主谐波导数的符号来考虑解的犹豫行为的影响，主谐波决定了迟滞回路的支路。

Complex Permeability Hysteresis Model for Implementation in Harmonic Balance Finite Element Method

A mathematical model of scalar hysteresis in a ferromagnetic medium is formulated. The model is based on the concept of complex magnetic permeability, including analytical expressions like the Fröhlich functions. The initial data of the complex permeability obtained from the Preisach hysteresis model. The features of the algorithm taking into consideration hysteresis phenomena in the harmonic balance method are formulated. Influence of the hesitating behavior of the solution is taking into account by the sign of the derivative of the main harmonic which determines the branch of the hysteresis loop.
