组装域结构模型（ADSM）是核心材料的基于能量的宏观磁化模型。在本文中，我们使用ADSM模拟了矢量激励下晶粒取向（GO）硅钢片的磁化曲线和磁致伸缩，并使用带有三元件应变片玫瑰花的旋转单片测试仪对同一片硅钢片进行了测量。在模拟中，表示单向或旋转磁通量的平均磁化矢量的目标值作为已知参数给出。我们通过求出外部磁场矢量和状态矢量来获得磁化状态，满足平均磁化矢量等于目标值并且总磁能局部最小化的标准。模拟重建了单向磁化下90度畴壁运动产生的磁致伸缩以及旋转磁化下的矢量收缩和延伸。
The assembled domain structure model (ADSM) is an energy-based macroscopic magnetization model of a core material. In this paper, we used the ADSM to simulate the magnetization curves and magnetostriction of a grain-oriented (GO) silicon steel sheet under vectorial excitations, and we measured the same sheet using the rotational single-sheet tester with a three-element strain gage rosette. In the simulation, the target value of the average magnetization vector representing unidirectional or rotational magnetic flux is given as a known parameter. We obtained the magnetization state by finding the external magnetic field vector and state vectors, satisfying the criteria that the average magnetization vector equals the target value and that the total magnetic energy is locally minimized. The simulation reconstructed the magnetostriction produced by the 90 degrees domain-wall motion under unidirectional magnetization as well as the vectorial contraction and extension under rotational magnetization.
