将水平集方法与双向进化优化(BESO)方法相结合,解决了热传导优化设计问题。众所周知,在优化过程中,水平集方法不能在结构中形成孔洞。为了解决这一问题,将BESO的材料去除方案与基于水平集的拓扑优化相结合。换句话说,孔洞是通过材料去除方案成核的。说明了孔形核的判据,并叙述了优化过程。算例结果证明了该方法的有效性和有效性。
The optimal design problem of heat conduction is solved by combining the level set method and the bi-directional evolutionary optimization (BESO) method. It is well known that the level set method is not able to nucleate holes in the structure during the optimization. In order to address this issue, the material removal scheme of the BESO is combined in the level set based topology optimization. In other words, hole is nucleated by using the material removal scheme. The criterion for hole nucleation is explained, and the optimization procedure is described. The results of numerical examples prove that the proposed method is effective and efficient.
