TOCOLOGY OPTIMIZATION IN IVtAGNETIC FIELDS

摘要

Topology optimization in magnetic fields has been studied based on the HDM (homogenization design method) and SIMP (Solid Isotropic Material with Penalization). Recently, the modified density approach that accepts the concept of the homogenization design method has been suggested. In this study, the results of topology optimization based on the objective functions such as maximizing magnetic force as well as maximizing the magnetic mean compliance are reviewed. Especially, the modified density approach is studied to obtain the improved final topology comparable to the results by HDM focusing on the hole-shape of the unit element structure considering the directional properties of the magnetic flux.
