组装畴结构模型（ADSM）是一种多尺度磁化模型，可用于模拟磁芯材料的磁特性。本文通过使用ADSM进行模拟，揭示了由于施加到硅钢片上的压应力引起的磁滞损耗增加的机理。还提出了一种简单的方法来调整模拟的磁滞损耗的测量损耗。通过在无应力条件下调整磁滞损耗，使用ADSM定量地重构了无取向硅钢片的磁滞损耗的应力依赖性，其中应力诱导的各向异性增强了沿着应力方向的钉扎效应。
The assembled domain structure model (ADSM) is a multiscale magnetization model that can be used to simulate the magnetic properties of a core material. This paper reveals the mechanism of the hysteresis loss increase due to compressive stress applied to a silicon steel sheet by conducting a simulation using the ADSM. A simple method of adjusting the simulated hysteresis loss to the measured loss is also proposed. By adjusting the hysteresis loss under a stress-free condition, the stress dependence of the hysteresis loss of a non-oriented silicon steel sheet is quantitatively reconstructed using the ADSM, where the stress-induced anisotropy strengthens the pinning effect along the stress direction.
