Abstract :
We proposed a new approach for estimating the vibration and noise caused by magnetoelectric effect and magnetic force via finite element analysis. With this method, the relationship between inputting magnetic field and outputting vibration level of laminated core structure in power transformer could be obtained. The essential reason of vibration is analyzed and a kind of nanocrystalline soft magnetic composite material (NSMC) with high permeability is applied to fill the air gaps between the sheets. It is intended to verify the correctness of this method, that a 3D magneto-mechanical strong coupling model containing anisotropic silicon steel sheets was built and solved. From the experimental results, the deformation and noise level with NSMC are significantly better than that with the traditional epoxy damping material based on Epstein Frame.
