A Level-Set Based Topology Optimization for Maximizing the Torque of Switch Reluctance Machines
Résumé
This paper presents a topology optimization algorithm based on a Level-Set method and continuum sensitivity analysis in a 2D magnetostatic finite element context. The novelty is the use of a fully analytical expression for the sensitivity analysis based on the virtual work principle and applied to a Level-Set implementation. The numerical study of a switch reluctance machine and the virtual work method to compute the torque are presented. Then, the Level-Set method is detailed in a general context. The corresponding continuum sensitivity analysis using the adjoint method to maximize the torque is expressed. Finally, the application of this method to the optimization of the rotor of a switch reluctance machine is shown.
