NURBS曲线是一种重要的样条曲线,可以高效拟合工业设计领域中的特殊型线、弧线等,由于船舶设计过程需要充分考虑流场的阻力特性,因此提升舰船型线和船体的设计水平很重要。本文研究的内容是一种基于NURBS曲线和曲面光顺理论的船体设计方法,设计过程融合了小波神经网络和OPENGL开发平台,建立了基于小波神经网络的船体曲线、曲面设计平台,对于提升船体型线、流场力学特性分析有最重要的实际应用价值。
NURBS curve is an important spline curve, which can efficiently fit special curves and arcs in the field of industrial design. Because the resistance characteristics of flow field need to be fully considered in the process of ship design, it is very necessary to improve the design level of ship profile and hull. The content of this paper is a hull design method based on NURBS curve and surface fairing theory. The design process integrates wavelet neural network and OpenGL development platform, and establishes a hull curve and surface design platform based on wavelet neural network, which has the most important practical application value for improving the hull line and flow field mechanical characteristics analysis.
