Abstract

Interpolation methods are very important in computational aeroelasticity in both the closely and loosely coupled analysis method. In this paper, the characteristics of thin plate splines (TPS), multiquadrics surface spline methods(MQ) and kriging method were first analyzed for interface data interpolation in computational aeroelasticity. Through the analysis of different methods, a hybrid interpolation method is proposed which combines the thin palte spline and kriging method. The AGRAD 445.6 wing is used to demonstrate the efficiency and accuracy of this method .The method can be used to exchange interface data of computational aeroelasticity.
