摘　　要：船体曲面结构优化设计是船舶设计中的重要环节,可以提高船舶的动力学性能和效率。本文提出一种基于非均匀有理B样条(NURBS)和小波变换的船体曲面结构优化设计方法,使用NURBS曲线和曲面建模方法对船体进行建模,基于NURBS曲线和曲面的灵活性和小波变换分解算法,结合OpenGL软件对船体曲线和曲面的形状进行寻优设计。结果表明,基于NURBS和小波变换的船体曲线、曲面优化设计的效率高、精度高。The optimal design of hull surface structure is an important part of ship design,which can improve the dynamic performance and efficiency of the ship.This paper proposes an optimization design method of hull surface structure based on non-uniform rational B-spline(NURBS)and wavelet transform.NURBS curve and surface modeling method is used to model the hull,and the flexibility of NURBS curve and surface and the decomposition algorithm of wavelet transform are based on it.The results show that the optimization design of hull curves and surfaces based on NURBS and wavelet transform is efficient and accurate.
