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.
