Efficient Design Using Successive Analytical Subproblems Method: Application to Axial Magnetic Couplings

We propose a simple, but efficient method for design problems. Instead of using directly, a heavy numerical code in an optimization process, we successively define some approximated subproblems because of an appropriate analytical model. These subproblems can then be solved exactly by a deterministic global optimization solver and the procedure is updated until the approximation matches a 3-D FEM computation. The method is applied to an axial magnetic coupling. Comparative results show the effectiveness of this approach, and real design cases are studied because of this method.
