摘要

采用独立粒子近似的方法对组装畴结构模型进行了有效的应力相关磁化分析。这简化了静磁计算。组装停止磁滞子来表示固定场，其中停止磁滞子的分布采用标量和矢量停止模型的识别方法确定。无需对应力相关测量进行参数拟合，即可成功预测应力相关损失。

Pinning Field Modeling Using Stop Hysterons for Multi-domain Particle Model

The stress-dependent magnetization of silicon steel is efficiently analyzed by applying an independent particle approximation to an assembled domain structure model. This simplifies magnetostatic computation. Stop hysterons are assembled to represent the pinning field, where the distribution of stop hysterons is determined using the identification methods of scalar and vector stop models. The stress-dependent loss is successfully predicted without parameter fitting to stress-dependent measurements.
