| Abstract: | This paper describes the radial basis function interpolation (RBF) in the hull of the basic principles and application of surface deformation. We use the method of being based on radial basis function interpolation of the hull surface modification and CFD software and optimization algorithms, successfully developed a hull lines optimization platform.The use of the platform for the U.S. Navy surface ships DTMB5415 were bow model line optimization, obtaining a optimal performance hull shape under the given constraints resistance. The results show that, based on radial basis function interpolation of the hull surface deformation method is effective and feasible, the establishment of the hull form optimization platform has a certain value in engineering applications. |
