Abstract:	摘要： This study investigated the effect of magnetostriction-induced core magnetomechanical vibrations and noise on the magnetic properties of power transformers. The magnetostriction of grain-oriented Si steels was found to be extremely sensitive to compressive stress applied along the rolling direction and to tensile stress applied along the transverse direction. The compressive stress increased the variation in the magnitude of magnetostriction, which is correlated with core vibration and noise. A 2D model of the power transformer was used to simulate the noise and vibration variables through a finite element analysis. 出版者： Melville: American Institute of Physics 出版日期： 2015-05-07 出處： Journal of applied physics, 2015-05, Vol.117 (17) 資源來源： AIP Journals (American Institute of Physics) 版權： 2015 AIP Publishing LLC. 識別號： ISSN: 0021-8979 識別號： EISSN: 1089-7550 識別號： DOI: 10.1063/1.4919040
