| 摘 要： | 本文对某拖网渔船在考虑渔具作用下的船体阻力进行研究,以不同纵倾角设定渔具影响的五种工况,对船体阻力进行性能预报,对其阻力成分进行了比较分析,得出不同阻力在不同工况时的变化情况。同时结合船模水池阻力实验,通过对数值模拟和实验结果分析得出,渔具对拖网渔船阻力的影响规律,从而预报船体阻力性能。

| Abstract: | In this paper, the hull resistance of a trawler under the action of fishing gear is studied. Five kinds of working conditions for fishing gear influence are set up with different trim angles. The resistance of the hull is predicted, and the resistance components are compared and analyzed, and the change of the resistance under different working conditions is obtained. At the same time, combined with the tank resistance experiment, the influence of fishing gear on trawl resistance is obtained by numerical simulation and experimental results, so as to predict the hull resistance performance. |
