摘要

船体曲面变形是实现船型优化的前提条件，基于径向基函数插值的曲面变形方法适合于船型水动力性能优化的需要。文中主要对径向基插值中的支撑半径求取方法进行了改进，提出了支撑半径的动态求取方法，重点考虑了可变点的分布和坐标变化量对支撑半径的影响。在此基础上，将改进的径向基插值方法运用到本团队开发的船舶水动力性能多学科综合优化平台，以Series60船型为研究对象，完成给定约束条件下的船型优化研究，证明该方法的可行性。

Abstract

Surface deformation of the hull is a prerequisite for the optimization of the ship shape. Surface deformation method based on the radial basis function interpolation is suitable for the optimization of the hydrodynamic performance of the ship. This paper mainly improved the method of obtaining the support radius in radial basis interpolation, and proposed a dynamic method for obtaining the support radius. It considered the influence of the distribution of variable points and the change of coordinates on the support radius. On this basis, the improved radial basis interpolation method was applied to the ship hydrodynamic performance multi-disciplinary comprehensive optimization platform developed by the authors team. The Series 60 ship type was used as the research object to complete the ship type optimization study under the given constraints and the feasibility of the method was proved.

Key words： interpolation of radial basis function; support radius; hull form optimization
