This paper presents a model of the magnetostrictive hysteresis loop with local maximum. The model is based on the differential equations describing magnetostriction due to the domain wall movement as well as domain magnetization rotation. The transition between these mechanisms of magnetization is quantified by the Maxwell⁻Boltzmann distribution. Moreover, the lift-off phenomenon in the magnetostrictive hysteresis loop is considered. The proposed model was validated on the results of measurements of magnetostrictive hysteresis loops of MnZnFeO₄ ferrite for power application and 13CrMo4-5 construction steel. The results of modeling confirm that the proposed model corresponds well with experimental results. Good agreement was confirmed by determination coefficient R², which exceeded 0.995 and 0.985 for MnZnFeO₄ ferrite for power application and 13CrMo4-5 construction steel, respectively.
本文提出了一种具有局部最大值的磁致伸缩磁滞回线模型。该模型基于描述由磁畴壁运动以及磁畴磁化旋转引起的磁致伸缩的微分方程。这些磁化机制之间的转变由麦克斯韦-玻尔兹曼分布进行量化。此外，还考虑了磁致伸缩磁滞回线中的提离现象。所提出的模型通过对用于电力应用的MnZnFeO₄铁氧体和13CrMo4-5建筑钢的磁致伸缩磁滞回线测量结果进行了验证。建模结果证实，所提出的模型与实验结果吻合良好。通过测定系数R²证实了良好的一致性，对于用于电力应用的MnZnFeO₄铁氧体和13CrMo4-5建筑钢，测定系数R²分别超过了0.995和0.985。
