概要: application/pdf<br />Journal Article<br />In this report, the forced vibrations of a rectangular plate subjected to electromagnetic force by an electromagnet are investigated theoretically by the finite element method, and the numerical results are compared with the experimental ones. The rectangular plate is fixed along one edge and free along the other three, and twelve rectangular elements are used in the finite element analysis. The electromagnetic force character is supposed to be uniformly proportional to the square of the exciting current of the electromagnet in each rectangular element according to the measured data about the magnetic flux density. The numerical results agree well with the experimental ones except for nonlinear vibration behaviors. Then, it is observed experimentally the the second order superharmonic and the one-second order subharmonic vibration s due to the nonlinearity of the electromagnetic force. 続きを見る
