抄録

In this paper, a structure analysis technique of the core by the magnetostriction was proposed. The magnetic flux density of each element is first calculated by using FEM. Then the magnetostriction of each element is calculated by using the measured result. A magnetostriction is given as initial strain, it changes into the force of each node, and structure analysis is performed.<br>The advantage of giving magnetostriction as initial strain is that it is able to reach force of a point of each element as a vector.<br>Moreover, modal analysis and frequency response analysis were performed.<br>As a result, it was clarified that the resonance was related to the frequency of magnetostriction and natural mode. Then it became possible to forecast the frequency to which core vibrated most.<br>Therefore, proposing analysis technique is very useful.
