摘要：NUBRS曲面建模技术是专为曲面复杂物体三维模型重建而设计的，能基于曲线和曲面的形式对目标地物三维模型的轮廓和外形进行准确精细的表达。本文介绍了一款基于NURBS曲面的船体三维建模程序Maxsurf Modeler，详细论述了应用该程序进行船体三维建模的流程，同时对三维模型的可靠性和适用性进行了CFD验证。静水阻力计算中，6种工况下的最大误差为2.29%。耐波性计算中，纵摇运动的计算误差最大，为19.32%。结果表明，采用Maxsurf Modeler完成的三维模型具有一定的可靠性。

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.
