结构拓扑优化作为现在迅速发展的结构化设计的一个分支,已得到广泛应用。基于渐进结构优化(ESO)方法,结合灰色理论中的专家群体评估法,得到一种新的处理多目标优化的方法。首先使用线性加权法对一平面简支梁进行优化分析得到三组拓扑结构。然后运用该新方法对同一算例进行优化得到三组拓扑结构。并将最终拓扑结构进行对比。
Abstract：Structural topology optimization as a branch of the structural design which is rapidly developed nowadays, has been widely used. In this paper, based on the evolutionary structural optimization method, which is combined with the expert group evaluation method of the gray theory, we get a new method for dealing with multi-objective optimization. Firstly, the linear weighting method is used to a simply supported beam and we get three topological structures. Secondly, the new method is used to optimize the same example, we also get three topological structures. Then, compare the topological structures.
