船舶快速性是影响航运经济的关键因素之一，以某双体船为对象，设计一种阻力预报与优化方案并成功降低其阻力：运用数值模拟技术，结合Lackenby变形方法，改进船体型线，并进一步通过调整片体间距优化阻力性能。结果表明：优化后的船型具有良好的阻力性能，与原船型相比，在设计工况Fr=0.572下，剩余阻力系数可减少13%；片体间距优化后，船体总阻力进一步明显降低。基于以上结果，本文提出的预报方法及优化方案能够有效地用于高速双体船性能预报及优化设计，可以为相关研究提供技术支持。
The rapidity of ships is one of the key factors affecting the shipping economics. A catamaran is studied to design a resistance prediction and optimization plan and reduce its resistance successfully: using numerical simulation technology combined with Lackenby deformation method to transform the hull profile, and further optimizing the resistance performance by adjusting the spacing of the slices. The results show that the optimized ship possesses a good resistance performance. Compared with the parent ship, the total resistance coefficient can be reduced by 13% under the design condition, Fr=0.572. After the optimization of the hull separation, the total resistance coefficient is further significantly reduced. Based on the above results, the prediction method and optimization scheme proposed in this paper can be effectively used for the performance prediction and optimization design of high-speed catamarans and provide technical support for the related researches.
