摘　　要：介绍了径向基函数插值(RBF)的基本原理及其在船体曲面变形中的应用。将基于径向基函数插值的船体曲面修改方法与CFD软件及优化算法结合,成功开发了船体型线优化平台。运用该平台对美国海军水面舰艇DTMB5415进行了艏部型线的优化设计,获得了给定约束条件下阻力性能最优的船体外形。结果表明,基于径向基函数插值的船体曲面变形方法是有效可行的,建立的船型优化平台具有一定的工程应用价值。Radial basis function interpolation （RBF） in the hull of the basic principles and application of surface deformation is described in this paper. The method which is based on radial basis function interpolation of the hull surface modification and CFD software and optimization algorithms is used to develop a hull lines optimization platform successfully.The usage 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 the hull surface deformation method is effective and feasible based on radial basis function interpolation, the establishment of the hull form optimization platform has a certain value in engineering applications.
