英文摘要：

In automatic optimization of hull form, one of the key technologies is modifying hull form parameters. In this paper, interpolation of the radial basis function was applied in three dimensional deformations of the hull, and how to select the radius of support set by Wendland Basic Function was focused on. A new method of determining the support radius by using Delaunay Triangulation was proposed. The module of hull form deformation was refined based on the interpolation of radial basis function, and was applied to typical hull form optimization. That laid a foundation for engineering application of hull form optimization.
