Abstract
In this study, examination on elastic vibration of a thin steel plate under magnetic field by using permanent magnets was carried out. Especially, consideration was performed on the effect of pole and arangemeht of the magnets. Based on the result of the basic study using a single degree of freedom model, examination for a steel plate was performed. The attractive force of the permanent magnets is analyzed by using the finite element method and the elastic vibration of the steel plate was calculated by the finite difference method. To verify usefulness of the permanent magnet system, experiments were performed for an elastic steel beam. As a result, it was confirmed that the permanent magnets could increase the damping factor of elastic vibration of the steel plate.
