摘要 铁磁材料在实际工况中的磁特性会受到来自外界温度、压力等非磁性因素的影响,而传统的磁滞模型很难准确地模拟磁性材料在复杂环境下的磁特性,直接影响到考虑多物理场耦合时电磁场计算分析的精确性。为解决这一问题,提出基于磁化机理的双轴磁滞算子,根据“磁化稳定状态能量处于极小值”的原理,构建了能够确定单个磁滞算子稳定磁化状态的八角星形线法则,建立能够同时考虑温度和压力影响的新型磁滞模型。该模型考虑了温度对磁性材料的饱和磁化强度和磁各向异性系数的作用,同时引入了压力影响磁滞算子分布函数的理论,从而能够更精确地模拟分析磁性材料在实际工作条件下的磁特性。最后通过实验对比,验证了磁滞模型的有效性和准确性。

Abstract:The design and performance analysis of the electrical equipment usually involve the coupling of electrical, magnetic, thermal, mechanical and other physical fields. With the development of numerical calculation technology of electromagnetic field and the improvement of computer performance, the electromagnetic field numerical simulation software has been widely used to analyze the coupling problem of electromagnetic field, thermal field and mechanical field. The magnetic properties of magnetic material under work conditions will be influenced by some non-magnetic factors, such as temperature and stress. However, these characteristics are difficult to be simulated by the traditional hysteresis models. In this paper, based on the microscopic magnetizationmechanisms of magnetic materials, a hysteresis elemental operator, which contains two easy axes and two hard axes, has been presented. Besides, with the help of the energy minimum principle, the octagonal law which can determine the orientation of the magnetization has been introduced. By taking into account the differences between the laboratory conditions and the practical engineering manufacturing and operation, the temperature-depended saturation magnetization, temperature-depended anisotropy, and stress-depended distribution function are introduced to the hysteresis elemental operator. With the employment of the Gaussian-Gaussian distribution function and the interaction field, a temperature and stress dependent hysteresis model is proposed to simulate the magnetic properties under different temperature and stress conditions. Finally, by comparing the simulation results with the experimental measurement results, the effectiveness and viability of this proposed hysteresis model have been confirmed.
