Shape optimization of conductor slab on an electromagnetic damper by boundary element method combined with finite element method

The optimum shape of a conductor slab on an electromagnetic damper is determined by an optimization technique by the use of the Lagrange method of multipliers taking a serious view of a compact design. Firstly, damping coefficients were obtained by analysis of the eddy current in the conductor slab by the boundary element method combined with the finite element method. The numerical result agrees well with the experimental result in our previous report. Secondly, the optimum dimension of rectangular conductor slab was obtained by the least-square method and the optimization technique. The result of the optimization is verified in good agreement with the result of the least-square method. Thirdly, the optimum shape of conductor slab determined by the optimization technique. Furthermore the result is verified by an experimention.
