摘　　要：为研究渔船在实际海浪中航行的阻力大小,优化船舶的阻力性能,本研究采用STAR-CCM+软件,以49 m远洋鱿鱼钓船船模为研究对象,分析了其约束运动模型在静水和迎浪情况下的阻力性能。通过对约束模型在不同波高和波长的波浪中的阻力进行计算,得出远洋鱿鱼钓船在不同海况下实船的波浪增阻情况,同时,对远洋鱿鱼钓船球鼻艏进行选型分析,比较鱿鱼钓船无球鼻艏和加装撞角型球鼻艏、上翘型球鼻艏后在波浪中的阻力大小。结果显示:船舶在两种典型海况下设计航速时的平均波浪增阻占静水阻力的25%和18%,与其他船型相比,撞角型球鼻艏船型波浪增阻为21.0%和14.7%,降阻效果最显著。本研究为远洋鱿鱼钓船设计初期航速和球鼻艏的设定提供了参考。In order to study the resistance of fishing vessels in real waves and optimize the resistance performance of fishing vessels,STAR-CCM+was used to model a 49 m deep-sea squid fishing vessel,and the resistance performance of the constrained motion model in static water and wave-up was analyzed.By calculating the resistance of the restricted model in the waves of different wave heights and wavelengths,the increase of wave resistance of the deep-sea squid fishing vessel under different sea conditions was obtained.In addition,the resistance of different bulbous bow shape(normal bulbous bow,upward-bending bulbous bow and embolon bulbous bow)in waves was compared.The results showed that the average wave resistance increased 25%and 18%at design speed in two typical sea conditions,and the wave resistance increased 21%and 14.7%in the embolon bulbous bow compared with other bulbous bow type.This study provided a reference for the determination of speed and bulbous bow in the early design stage of ocean squid fishing vessel.
