摘　　要：为满足船舶线型优化设计的需要,提出一种基于非均匀有理B样条曲线(non-uniform rational b-splines,NURBS)面元的船舶静水力计算方法,并开发了基于NURBS面元的高拟合精度的船舶静水力计算程序,作为船型优化设计中的船舶静水力参数计算模块。最后以DTMB5415船型作为研究对象,采用该计算方法与商业软件计算结果进行对比。结果表明,基于NURBS面元的船舶静水力计算方法具有较好的适用性和计算精度,能够满足船型优化设计的需要。To meet the needs of ship line shape optimization design,a ship static hydraulic calculation method based on non-uniform rational B-spline(NURBS)panel elements is proposed,and a high fitting accuracy ship static hydraulic calculation program based on NURBS panel elements is developed as the ship static hydraulic parameter calculation module in ship shape optimization design.Finally,the DTMB5415 ship type is taken as the research object,and the calculation method is compared with the results obtained from commercial software.The results show that the ship static hydraulic calculation method based on the NURBS panel has good applicability and calculation accuracy,and can meet the needs of ship-type optimization design.
