参数化方法的中型豪华游船特殊球艏线型优化

摘要

以一艘中型豪华游船为例,在分析豪华游船船型特点的基础上,对其球鼻艏线型进行了优化.优化过程中采用参数方法生成了一系列球鼻艏线型,通过CFD方法对其兴波阻力和总阻力进行评估分析,并通过灵敏度分析得到对阻力影响最为显著的参数,获得了阻力性能较好的球鼻艏线型方案.最后通过模型试验对优化线型进行了模型试验验证,试验结果表明文中优化的线型具有良好阻力性能,为进一步开展豪华游船线型设计提供良好的技术参考.%According to the study on the lines characteristic of luxury cruises, the bulbous bow of a medium-sized luxury cruise ship is optimized in this paper.Parametric design method is utilized to generate a series of bow lines,and the resistance is evaluated by CFD.Sensitivity analysis is also carried out to identify the most suitable and relevant parameters,and an optimized lines is obtained.Then the model test for the optimized lines is carried out in towing tank at CSSRC,and the model test results show the optimized lines is of good resistance performance.
