| Abstract: | This paper discusses an approach of optimization for wing structural configuration with surrogate models and introduces the process how to obtain the surrogate models for structural analysis.The process includes the selection of variables and ranges of their values,design of experiments,parametric modeling of wing configuration,structural optimization design using FEM software,distilling structural characteristic from FEM simulation output,and construction of surrogate models.A wing structural configuration optimization is used to demonstrate the feasibility and effectiveness of the approach. |
