摘要
船舶数值模型是研究船舶操纵的有效方式,对于提高船舶航行安全具有重要的现实意义。本文在深海中船舶操纵模型的基础上,根据浅海航行的特点,对模型中的螺旋桨的干涉参数、力矩等因素进行修正,最后进行浅海中船舶回转仿真实验,实验结果表明浅海中,船舶吃水变小,回转圈直径则变大。
Ship numerical model is an effective way to study the ship maneuvering,which has important practical significance for improving the safety of ship navigation. Based on the deep sea ship handling model and characteristics of shallow water navigation,interferometric parameter propeller in model,torque and other factors were corrected. Finally,the ship in shallow water rotary simulation experiment results show that The ship' s draft became smaller,while the turning circle diameter was larger.
