Abstract
In this study, the optimum shape of the magnetic pole on an electromagnetic damper is determined by means of an optimization technique with an eye to compact design. The Lagrange multiplier method was used as the optimization technique. Firstly, damping coefficients were evaluated from the distribution of eddy currents occurring in the conducting slab. The distribution of eddy currents was calculated by the boundary element method combined with the finite-element method. Secondly, the optimum shape of the magnetic pole was obtained by the optimization technique under several conditions. Thirdly, each optimum pole shape was verified experimentally through comparison between the experimental value of the damping coefficient and the objective value.
