| Abstract (English): |
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. [ABSTRACT FROM AUTHOR] |
