The Evolutionary Structural Optimization（ESO） method is easily utilized to be programmed, and is of wide engineering applications, and may be adopted to obtain the optimum structure with black and white distribution material property. However, it＇ s difficult to solve the problem of muhi-constrained topology optimization by using it. To extend this method to the case of multi- constrained topology optimization, for the problem of topology optimization with multiple displacement constraints, the relationship between the stiffness and the topo...
