| 摘 要： | 在满足排水量及航速要求情况下设计出性能优良的船体型线,降低船体阻力、节能降耗是造船界一直所追求的目标。船舶球首的大小、位置和形状对船体兴波影响非常大,因此文章通过船型参数化融合方法,生成一系列球首型线,并以兴波阻力最小为目标,采用遗传算法实现球首型线的自动优化。将上述方法应用于某集装箱船球首型线的自动优化,并进行船舶静水阻力实验,实验表明优化船型在设计航速附近总阻力降低明显,说明文中采用的基于CFD船型自动优化方法是可行的。

| Abstract: | The bow’s size, location and shape have great effect to the wave resistance. So this paper generated a series of bow’s line using parametric morphing method, and realized the automatical optimization of bulbous bow lines with the goal of minimum resistance using genetic algorithm.Appling the above method to a container bulbous bow lines automatical optimization, the resistance experiment in calm water was carried out, and the experiment results indicated that the total resistance of optimized hull form nearby the service speed reduced obviously.It confirmed that hull form automatical optimization based on the CFD is feasible. |
