采用目标规划法对某实际工程结构的结构重量和翼梢位移进行了结构多目标优化设计。通过分析该工程结构的有限元模型,建立了其结构多目标优化的目标规划模型,并在给定载荷下利用拟合搜索策略对该模型进行了优化计算,得到了最满意结构尺寸。证明了目标规划法在实际工程结构多目标优化设计中应用的有效性。
Aiming at the structural weight and tip displacement of an actual engineering structure, a multi-objective structural optimization design is carried out by using the target programming method. By analyzing the finite element model of the engineering structure, a multi-objective optimization programming model of the structure is established. The model is optimized and calculated under a given load using the fitting search strategy, and the most satisfactory structure size is obtained. It proves the effectiveness of the target programming method in the multi-objective optimization design of the actual engineering structure.
