| 高质量的船型优化要求船型样本数量尽可能多.寻求一种高效率、高质量的船体几何重构方法在船舶设计初期具有重要意义.将船型融合技术与参数化相结合,提出一种基于可视化编程环境的船体几何重构方法,实现计算机依据设计变量自动生成大量船型样本的目的.通过在可视化编程环境下对若干船型样本进行快速阻力预报,选出了阻力性能优于母型船的船型.并设计出一套基于遗传算法的型线光顺可视化程序,解决了融合过程中型线的光顺问题,加快了船舶设计初期船型优化的效率,验证了基于可视化编程环境的船型参数化融合方法应用于船型优化的可行性. |

| High quality hull form optimization requires hull form samples as much as possible. So, it′snecessary for the early ship design to search for a highly efficient, qualified hull geometry modification and reconstruction approach. In order to automatically generate a large number of hull form samples by computer according to the design variable, a hull geometry modification and reconstruction approach in visual programming environment is offered combining the hull geometry morphing and parameterization. The rapid resistance prediction of several hull form samples in visual programming environment makes the hull form whose resistance performance excels the parent ship is selected. And by designing a visual program of the profile line smoothing based on the genetic algorithm, it can solve the smooth problem of profile lines in the process of the morphing, and promote the efficiency of the hull form optimization in the initial stage of the ship design. It is verified that the application of the hull form parametric morphing method based on visual programming environment to hull form optimization is feasible. |
