The evolutionary structural optimization algorithm with the grey weight expert group evaluation method

LI Hai-jun;LUO Jing;GONG Jiao;College of Mechanical Engineering, Chongqing University;  
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.
