Abstract

In this paper, combined analysis method of Electromagnetic and Structure analysis which describes how the magnetic steel sheet deformed by specifying the direction of nodal force against the element, in case the magnetic flux was distributed on it, was proposed. Deformation by magnetostriction of the magnetic steel sheet using structure and electromagnetic numerical analysis, and analysis of natural frequency and the result of measurement confirmed that the resonance occurred when magnetostriction frequency and natural frequency of the magnetic steel sheet were getting close. Also, larger resonance was confirmed when the shape of magnetic core deformed by magnetostriction and the eigen mode were close.
