摘　　要：为了研发低阻、高耐波性新船型,以某圆舭船型为参考船型,设计了穿浪内倾深V型主船体,并设计了半潜艏和水滴形球鼻艏两种形式的艏部附体。基于CFD数值模拟分析不同主船体和艏部附体对于船舶横摇稳定性、静水阻力和耐波性的影响。通过水池模型试验进一步研究不同船型的耐波性,并验证了CFD数值方法的准确性。研究表明,深V船型的横摇和纵摇稳定性优于圆舭船型,且在高航速时深V船型的静水阻力性能也优于圆舭船型。在高航速下,水滴形球艏有利于减小深V船型的兴波阻力和波浪增阻,而半潜艏对于提高船舶纵向稳定性具有更加显著的效果。In order to develop novel ship types with lower resistance and better seakeeping performance,wave-piercing deep-V hull and two kinds of bow appendages,i.e.,semi-submerged bow and water drop shaped bulbous bow,are developed in this paper.Rolling stability,resistance in calm water and seakeeping performance of various hulls with different bow appendages is investigated with CFD numerical simulation.In addition,experiments of tank models are conducted to further investigate ship seakeeping performance and validate the CFD algorithm.It is indicated that the deep-V hull has better roll and pitch stability than the round bilge hull.The deep-V hull also has better resistance performance in calm water than the round bilge hull in high speed conditions.The bulbous bow with water drop shape is helpful to reduce wave-making resistance and added resistance in waves of the deep-V hull at high speed.The semi-submerged bow has a more significant effect on improving longitudinal stability for the deep-V hull compared with the water drop shaped bulbous bow.
