摘　　要：变压器或电机铁心存在大量旋转磁通,旋转磁化下铁心硅钢的磁滞与磁致伸缩效应将增大铁心损耗,加剧铁心振动形变。为了有效模拟铁心硅钢磁滞与磁致伸缩耦合特性,本文在实验测量基础上提出将旋转磁化下硅钢的涡流损耗与异常损耗引入到传统Jiles-Atherton磁滞模型能量平衡模型,表征电工钢片的旋转磁滞特性。同时,基于磁致伸缩与磁化强度之间的非线性回环曲线关系,建立旋转磁化下一阶惯性磁致伸缩模型,并将磁滞模型表征的磁化强度映射到磁致伸缩模型中,建立磁滞与磁致伸缩特性的耦合关系。最后通过实验验证了模型的有效性。研究结果表明,提出的耦合模型可以有效地表征电工钢片的旋转磁特性,为高品质电工产品的优化设计提供参考。There is lots of rotational magnetic flux in transformer cores or motor cores.The hysteresis and magnetostrictive properties of silicon steels of core under rotational magnetization will increase the core loss and vibration deformation.In order to model the coupled hysteresis and magnetostrictive properties in the core silicon steel effectively,based on experimental data,this paper proposes that the eddy current loss and abnormal loss of electrical steel sheet under rotational magnetization are introduced into the energy balance formula of traditional Jiles-Atherton hysteresis model to characterize the rotational hysteresis characteristics of electrical steel sheet.At the same time,based on the nonlinear loop curve relationship between magnetostriction and magnetization,the first-order inertial magnetostrictive model under rotational magnetization is established.The magnetization intensity characterized by the hysteresis model is mapped to the magnetostrictive model,and the coupling relationship between hysteresis and magnetostrictive characteristics is established.Finally,the effectiveness of the proposed model is verified by experiment.The results show that the proposed coupling model can effectively characterize the rotational magnetic properties of electrical steel sheets,and provide a reference for the optimization design of high-quality electrical products.
