The invention discloses a bulbous bow structure capable of reducing ship wave-making resistance and a processing technology of the bulbous bow structure, and relates to the technical field of refitting design of operating ship bulbous bows, the bulbous bow structure is additionally arranged on the bow portion of a bulbous bow ship type in a welding mode, the bulbous bow molded line of the bulbous bow structure is in an upwarp shape, and the bulbous bow molded line of the bulbous bow structure is in an upwarp shape. The overall shape of the bulbous bow structure is thin and short. The machining process comprises the steps of S1, product design; s2, optimizing and adjusting; s3, producing and processing; and S4, adding a product. According to the bulbous bow structure capable of reducing the wave-making resistance of the ship and the processing technology of the bulbous bow structure, the bulbous bow is designed and transformed into a thin and short type, and the molded line of the bulbous bow is designed into an upwarp shape, so that the bulbous bow structure can achieve the minimization of the wave-making resistance and reduce the influence of the wave-making resistance on ship navigation, and a bulbous bow optimization frame is constructed through a CFD method; the molded line of the bulbous bow is changed, various parameters of the bulbous bow are optimized and adjusted with the aim of minimizing wave-making resistance, and better propulsion efficiency of a ship is achieved.

    本发明公开了一种减少船舶兴波阻力的球鼻艏结构及其加工工艺,涉及营运船舶球鼻艏改装设计技术领域,球鼻艏结构加装在球鼻艏船型的艏部,且加装采用焊接方式,球鼻艏结构的球鼻艏型线为上翘形,且球鼻艏结构的整体形态呈瘦短型,加工工艺包括:S1、产品设计;S2、优化调整;S3、生产加工;S4、产品加装。该减少船舶兴波阻力的球鼻艏结构及其加工工艺,通过将球鼻艏设计改造为瘦短型,并将球鼻艏型线设计为上翘形,使得球鼻艏结构可以实现兴波阻力最小化,减少兴波阻力对船舶航行的影响,并通过CFD方法构建球鼻艏优化框架,更改球鼻艏型线,以兴波阻力最小化为目标对球鼻艏各项参数进行优化调整,有助于船舶实现更好的推进效率。
