摘要 谐波分量会引起电气设备激励波形畸变,使铁心损耗增加。为研究该工况下铁心材料磁特性的变化,该文将畴壁移动时的复杂能量变化和最小化过程简化为驱动力,将阻碍畴壁移动的钉扎力简化处理为粘滞摩擦力,由此采用非线性力学Bouc-Wen模型对材料的磁滞现象进行描述。通过引入表征磁畴磁化的旋转项对Bouc-Wen模型进行修正,采用修正模型实现准静态条件下的磁滞回线模拟。通过进一步考虑涡流引起的阻力项,扩展该模型为动态模型,能够模拟不同频率的正弦以及高阶谐波激励条件下的非对称回线,并详细讨论了不同激励条件下所提出模型中的阻尼系数的变化规律及其频率效应。通过对比实测结果与模型预测结果,验证了模型的正确性与准确性。

Abstract:The excitation current of electrical equipment is distorted by harmonic components, which causes a significant increase in iron loss. This paper analogizes the complicated energy change and minimization of total energies during the domain wall motion to the driving force and simplifies the pinning force hindering the domain wall motion as viscous friction. Therefore, the nonlinear hysteretic mechanics Bouc-Wen model is adopted to characterize the hysteresis phenomenon. The initial model is modified by adding new terms that characterize the rotation of domain magnetization. The modified model is used to simulate the hysteresis loops under quasi-static magnetization. The model is further modified to a dynamic model by taking account of the resistance caused by the eddy current, then the loops under sinusoidal excitation with different frequencies and high order harmonics are simulated. The variation and frequency effect of parameters representing the damping coefficients under different excitations are discussed. Finally, the comparison between the measured and calculated results shows good agreement, and the accuracy of the proposed model is validated.
