On the coupling of reanalysis techniques with a surrogate-based design optimization method

摘要

In this research, a Surrogate-Based Optimizationud(SBO) method is coupled with reanalysis techniquesudto improve the computational efficiencyudduring optimization even further. The reanalysisudtechniques are used to speed up a reduction anduda substructuring method, Craig-Bampton, whichudis utilized at the analysis step of the proposedudSBO strategy. This strategy is suitable for solvingudproblems where the modal and the harmonicudresponses of structures are required to be modified.udAn academic test problem is utilized for theuddemonstration.
