摘要
该文基于波形叠加的消波原理,对一艘仿阿雷.伯克级大型驱逐舰加装减阻节能球鼻艏进行研究,研究表明大型驱逐舰加装减阻节能球鼻艏可获得较好的减阻效果。文中首先给出了基于细分曲面表达船型,采用船体曲面法向量分量表示源强的船舶兴波阻力及波形计算的数值方法,通过与实验结果的比较,分析了该方法的合理性和有效性;在此基础上通过逆向设计法优化计算和分析得到了一仿阿雷.伯克级大型驱逐舰船型加装减阻节能球鼻艏消波减阻定性规律和定量效果,在特定的中高航速下通过减阻节能球鼻艏优化设计可以使兴波阻力最多减少33.7%。
It has been known that wave making resistance of high speed surface warship can be significantly reduced with a proper bulbous bow. In this article, a method for calculating wave making resistance and wave profile is given at first, which is based on subdivision surfaces and by employing ship surface normal vector component to express the source density. The calculation method was validated by the results of experiment and it shows the method＇s availability, Based on this method, optimization analysis for bulbous bow of a concept large destroyer was investigated and it shows that about 33.7% maximum decrease of wave making resistance can be achieved at a given speed by using the optimum bulbous bow.
