| 摘 要： | 介绍了一个模拟铁磁元件磁滞特性的新数学模型。铁磁元件多值的磁滞特性被等值地模拟为一个极限磁滞回线和局部磁滞回线，极限磁滞回线由三次样条函数表示，局部磁滞一则按逆转点的位置及从极限磁滞回线开始的一非线性变化的纵向位移来生成。

| Abstract: | A novel mathematical model for simulating the magnetic hysterisis characteristics of ferromagnetic components is introduced. The multi valued magnetic hysterisis characteristics of the ferromagnetic components is simulated as a major magnetic hysterisis loop and a set of minor magnetic hysterisis loop trajectories. The major magnetic hysterisis loop is represented by cubical splines, and the minor magnetic hysterisis loop trajectories are generated in terms of a simplified vertical nonlinear displacement of the inversion point from the major loop. |
