BESO method for topology optimization of structures with high efficiency of heat dissipation

Abstract

The purpose of this paper is to present a Bi-Directional Evolutionary Structural Optimization (BESO) method for topology optimization of heat conduction structures. In BESO method the elements are allowed to be added as well as removed. Focused on the heat performance of structure, the additive criterion and rejection criterion were proposed respectively. With the limit volume of the high conductive material, the optimal layout of structure with high efficiency of heat dissipation and uniform temperature distribution can be obtained efficiently by BESO procedure.
