船舶横向力与舵力对船舶操纵性的综合影响

General influence of propeller's cross force and rudder force for ship's manoeuvrability

通过对单桨单舵船系泊正车时的舵力、螺旋桨推力的估算与此时船舶横向力实验结果的对比分析，对舵力与船舶横向力进行量级分析，同时对系泊倒车时的舵力、船舶横向力的量级关系进行推广，提出利用船舶横向力与舵力的综合作用改善船舶操纵性，特别是在低速靠离码头时要充分注意ｈ／Ｄ，ｂ／Ｄ的数值对舵力与船舶横向力量级的影响．

This paper analyses rudder force, propeller's thrust and propeller's cross force and the experiment results for a ship with signal propeller and signal rudder in the state of getting alongside wharf which is similar to berthing condition. By contrasting'the power relationship between ship's rudder force, propeller's cross force, it suggests that officers must take caution with h/D, b/D and propeller's cross force when getting alongside or leaving wharf at lower speed.
