考虑位移约束的结构布局优化方法
A Structural Layout Optimization Method Considering Displacement Constraints
摘要
Abstract
A continuum structural optimum method considering simultaneously both the topology and the size design variables was investigated herein. In the proposed method,the combinatorial optimization of two kind of variables was transformed into continuous variables between 0 and 1 by normalization method and the RAMP(rational approximation of material properties) material model. Based on dual optimization method, a new solving algorithm of optimum model and an adjustment scheme of topology design space and size variables were presented. Two examples were given, the results show that the proposed method is of good convergence, and makes the optimum structure obtained be of good 0-1 distribution material property.关键词
