Research on CAD modeling of main hull model based on NURBS surface theory
This article studies the theory of NURBS surfaces,with a focus on analyzing the definitions and expressions of NURBS curves and surfaces.It provides a calculation method for B-spline curves,studies the solution method for smooth-ing ship curves and surfaces,and introduces the definition of the sum of squared shear jumps;Studied the calculation meth-od for three-dimensional stability of ships and the algorithm for solving the static stability force arm of ships,and analyzed the variation curve of the static stability force arm and the variation curve of the ship's draft depth;Finally,the CAD model-ing technology for ship hull models was studied,and a design method for a fast ship modeling system was provided.
