電磁鋼板の応力依存磁化特性表現のための磁区モデルにおける2段階エネルギー極小化

抄録

The multi-domain particle model for the magnetization analysis of electrical steel sheets requires long computation time when the applied magnetic field is large. In this study, we propose a method that can efficiently minimize the internal energy in two steps: the energy minimization by domain wall motion and the energy minimization including magnetization rotation. The proposed method can significantly reduce the computation time while maintaining the accuracy of magnetization analysis.
