摘要
螺旋桨在波浪中随船运动,总的状态应该是前进、旋转和振荡三者结合的。本文为了近似计算波浪中桨流体动力性能相对与静水的变化,将波浪中运动的螺旋桨分解为旋转兴波和振荡兴波两部分线性迭加。利用GYen函数法,求解其兴波问题,从而给出桨推力的变化值。文章根据编制的程序进行了系列数值计算。结果表明:波浪中螺旋桨推力系数变化值随桨轴浸深、桨升沉振荡频率和幅值而变化.
For calculating open water characteristics of a propeller in waves, the problem is considered as two separated ones: one is the wave-making of propeller oscillation, the other is foe wave-making of propeller rotation .The two problems are solved using Green function method. A computer program is developed according to the present method, and a series of numerical calculations calculatinos are made with the program.The result shows that the propeller thrust depends on submergence, frequency and axnplitude of propeller oscillation.
