大型船舶造型设计参数众多，难以通过设计人员简单的分析来确定最佳的造型设计方案，本文研究基于势流计算的大型船舶型线设计。以母型船为基础，用母型融合法整合不同母型船优势特征，由变换函数灵活设定大型船舶造型设计参数；设定大型船舶造型设计参数时，构建基于势流计算的船型优化目标设计模型，设计船型优化目标为兴波阻力最小化，并界定大型船舶造型设计的优化变量取值区间，在CFD中使用Shipflow软件，由势流计算方法，求兴波阻力最小的造型设计方案。研究结果显示，该方法模拟设计的大型船舶模型，相较于母船，不仅实现了兴波阻力的显著降低，其航行时的波高起伏也更为平缓，充分验证该设计方法在提升船舶水动力性能方面的有效性。
There are many parameters in the shape design of large ships, so it is difficult for designers to determine the best shape design scheme through simple analysis, and to study the shape design of large ships based on potential flow calculation. This method is based on the mother ship and integrates the advantageous features of different mother ships using the mother ship fusion method. The design parameters of large ship shapes are flexibly set by the transformation function; When setting parameters for the design of large ship shapes, a ship shape optimization objective design model based on potential flow calculation is constructed. The design optimization objective of the ship shape is to minimize the wave making resistance, and the range of optimization variables for the design of large ship shapes is defined. In CFD, the SHIPLOW software is used to calculate the shape design scheme with the minimum wave making resistance using potential flow calculation method. The research results show that the large ship model simulated by this method not only achieves a significant reduction in wave resistance compared to the mother ship, but also has smoother wave height fluctuations during navigation, fully verifying the effectiveness of this design method in improving the hydrodynamic performance of ships.
