Abstract

In this paper, the fundamental characteristics of the electromagnetic damper are investigated by the finite element method. The reaction of the magnetic field excited by the eddy current is considered in the formulation. Firstly, the eddy current in the conductor slab is calculated for a slab moving at a constant velocity perpendicular to the magnetic flux density, and the attenuation coefficients are evaluated in accordance with the calculated values of the eddy current. Secondly, the effects of the reaction of the magnetic field are analyzed by the finite element method and Runge-Kutta method in a couple problem involving the magnetic field and the vibration of the slab. Thirdly, the numerical results are verified through experimentation.
