摘　　要：基于生成对抗网络模型,在船体型线参数化的基础上,建立了船型特征参数到船体型线几何点坐标的映射,形成了一种基于船型特征参数的船体型线逆向重构方法。在含有450余个样本的超大型油船数据集上开展了应用研究,对比两种参数组合的逆向重构效果。经CFD方法验证,建立的船体型线逆向重构方法能够更加快速地生成船型几何,与原型相比,重构船型总阻力系数的CFD计算误差约为1%~2%。Based on the generation of adversarial network and parameterization of the ship shape,a mapping method from characteristic parameters of the ship shape to coordinates of geometric points on the ship shape is established,and then a reverse reconstruction method of the ship shape based on its characteristic parameters is formed.Application research on reverse reconstruction of a large oil tanker is carried out based on the data set with more than 450 samples included,and reverse constructions from two parameter combinations are compared.It is verified that the method can generate ship’s geometry quickly according to given parameters.Compared with the total drag coefficient of the prototype,the error of that by the CFD calculation is about 1%~2%.
