Abstract

The application of the multilevel optimization algorithm proposed in the first part of the article is described. The weight minimization of a simple wing-box composite structure is chosen to validate the algorithm and to prove its effectiveness. To integrate all levels, codes and software of the algorithm, special optimization software, Noesis Optimus, is used. The upper-level optimization method is a hybrid optimization algorithm based on an interpolating response surface model. The MSC Nastran is used to calculate structural responses. Several runs of the entire multilevel algorithm were performed. The results obtained showed that the optimization multilevel algorithm proposed is very effective. It allows one to find the lighter designs in a shorter time or using lesser computational resources in comparison with the algorithms developed previously.
