Rapidly Coupling Parametric Optimal Design of Partial Structure Modification for Integral Body

Abstract:

A parameterized model for local modification structure is built coupled with the finite model to generate a local parametric coupling model. According to the performance, the credibility of the fast coupling parameterization modeling and the accuracy of the local parametric coupling model could be confirmed. Besides, the approximation established by design of experiments and radial basis function can predict the performance of the body successfully and the hybrid method multi-objective optimization can be used to achieve multi-objective optimization design. Therefore, the method built can meet the design effectiveness while saving modeling time and improving optimization efficiency.
