Abstract

In order to use more accurate and fair hull model in ship CAD/CAM/CAE system, based on the hull offset data, the NURBS representation of the conventional station ordinates and generalized station ordinates are obtained by interpolation or approximation method. After obtaining these curves, the same number of data points is sampled from these curves by dividing its arc length equally, so as to form generalized offset points. By interpolation of these generalized offset points, compatible conventional station ordinates and generalized station ordinates are reconstructed, and these curves together constitute the cross-section curves of the hull surface. These cross-section curves are taken as u-direction isoparametric curves of hull surface. By using improved surface lofting method, the whole hull surface is gotten. From the results, it can be seen that the reconstructed hull surface has good fitting accuracy and fairness.
