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

Abstract

In this research, a Surrogate-Based Optimization (SBO) method is coupled with reanalysis techniques to improve the computational efficiency during optimization even further. The reanalysis techniques are used to speed up a reduction and a substructuring method, Craig-Bampton, which is utilized at the analysis step of the proposed SBO strategy. This strategy is suitable for solving problems where the modal and the harmonic responses of structures are required to be modified. An academic test problem is utilized for the demonstration
