摘要 电工钢片的磁致伸缩现象是引起电机、变压器铁心振动的一个重要原因。磁致伸缩特性与铁心的磁化方式密切相关。电机定子铁心存在大量旋转磁场,相比于交变磁化,旋转磁化会引起更大的磁致伸缩应变,准确模拟旋转磁化下电工钢片的磁致伸缩特性是实现电工产品性能优化的前提和基础。该文借鉴Jiles-Atherton(J-A)磁滞模型对磁化过程中磁畴畴壁移动和磁矩转动而产生滞后行为的表征方法,提出一种能够描述旋转磁化下磁致伸缩正应变和剪切应变矢量、滞后特性的磁致伸缩模型。基于电工钢片旋转磁特性测量系统提供的特性数据,采用粒子群优化算法实现了模型参数辨识,并验证了模型的准确性。制作并搭建硅钢叠片铁心局部磁致伸缩特性测量系统,给出了所提磁致伸缩模型计算铁心磁致伸缩形变的具体过程,通过与测量结果的比较,进一步分析了所提理论模型的有效性。研究表明,旋转磁化下电工钢片磁致伸缩具有滞后行为,该文从磁化机理角度提出的磁致伸缩模型可以有效地表征这种特性。

Abstract:The magnetostrictive phenomenon in the electrical steel is an important cause of vibration of the iron core in motors and transformers. Magnetostrictive characteristics are close related to magnetization patterns of iron cores. There is a large amount of rotating magnetic field in the stator core of electric machines, and compared with alternating magnetization, the rotating magnetization will cause greater magnetostrictive strain. Therefore, accurately modeling the magnetostrictive characteristics in an electrical steel sheet under rotating magnetization is the basis and premise for optimizing the performance of electrical equipment. In this paper, using the Jiles-Atherton (J-A) hysteresis model to characterize the hysteresis behavior caused by the movement of the magnetic domain wall and the rotation of the magnetic moment during the magnetization process, a magnetostrictive model that can describe the vector and hysteresis characteristics of magnetostrictive normal and shear strains under rotating magnetization is proposed. Based on the characteristic data in an electrical steel sheet provided by the rotating magnetic characteristic measurement system, the particle swarm optimization algorithm was used to identify model parameters, and the accuracy of the model was verified. A measurement system of local magnetostrictive properties in silicon laminated cores was set up, and the specific process of calculating the magnetostrictive deformation of the core was presented. By comparing with the measurement results, the validity of the model was further investigated. It is shown that the magnetostriction of electrical steel sheets under rotating magnetization has hysteresis behavior, and the proposed model can effectively predict this kind of characteristics.
