Abstract:

NUBRS surface modeling technology is specially designed for the reconstruction of 3D models of complex surface objects. It can accurately and precisely express the contour and shape of the 3D model of target objects based on the form of curves and surfaces. This paper introduces Maxsurf Modeler, a 3D modeling program of hull based on NURBS surface, and gives the process of applying this program to 3D modeling of hull. At the same time, the reliability and applicability of the 3D model are verified by CFD. In the calculation of hydrostatic resistance, the maximum error under 6 working conditions is 2.29%. In seakeeping calculation, the calculation error of pitch motion is the largest, which is 19.32%. The results show that the 3D model completed by Maxsurf Modeler has certain reliability.
