多学科协同优化方法的分析与改进

深入分析了标准协同优化、动态松弛协同优化和两阶段协同优化方法的几何特性,进而比较了各自的优化特性.针对协同优化对初始点敏感的问题,通过增加总体一致性约束的方法,提出了基于先验约束法的SGO方法.针对设计变量数量级相差较大的协同优化问题,为了提高学科间的一致性,给出了基于加权方法的学科间一致性约束表示式.最后,通过悬臂梁...

Analysis and Improvement of Multidisciplinary Collaborative Optimization

Standard collaborative optimization,collaborative optimization based on variable relaxed tolerance and collaborative optimization based on two-phase optimization were analyzed and their optimizing properties compared,all from a geometry point of view.In view of that the optimization results of collaborative optimization were vulnerable to the initial points.A new SCO method based on prior constraint is proposed by adding the total consistency constraint.Aiming at the collaborative optimization problem whose...
