摘要
根据Guldhammer和Harvald图谱估算船舶的剩余阻力系数,运用Nordstm模桨系列图谱和换算系数估算船舶的四象限螺旋桨特性曲线,在船舶吃水船长比处于不同的范围时运用不同的方法计算倒车横向力,考虑了舵力和风力对停船运动的影响。运用MMG模型,对"Mariner"轮和"乐荣"轮进行了倒车停船运动仿真试验,并与相应的两船实船试验结果进行了比较,两者基本符合。
The Guldhammer and Harvald charts are applied to solve ship＇s residual resistance coefficient, and the four quadrants characteristics of ship＇s propeller is estimated by Nordstoem propeller model diagrams with a conversion coefficient, and the transverse force caused by reverse propulsion is calculated by different methods according to different range of ratio of draught to length, and the rudder force and wind force are taken into account. According to the MMG model, simulations of ship stopping motion by reverse propulsion on ship ＂Mariner＂ and ship ＂Taohe＂ were carried out, and good agreement has been arrived at comparing with the results of experiments on the two ships.
