摘要
停船操纵是一种重要的船舶操纵,尤其是从避让的角度出发.由于在停船过程中船舶的运动极为复杂,因而研究这种操纵运动是很必要的.本文考虑了右旋单桨船的浅水效应,通过模拟计算,研究了停船航迹、漂角、首向角随时间变化的关系,模拟结果和自航模试验结果进行了比较,两者吻合较好.在此基础上,笔者模拟了几种不同的避让操纵方法,并进行了比较,得到了几种不同条件下实用而有效的避让操纵方法.
Stopping is a very important ship manoeuvre,especially in view of avoiding collision.
It is necessary to know the characteristics of this manoeuvre because the ship' s motion during stopping is very complex. In this paper, the shallow water effects of stopping ships with righthanded single screws are investigated, by simulation, about the stopping path, drift angle and heading angle,which very with time. The simulated results are compared with the free-running model tests and it shows that they are in general coincidence. Then,a variety of avoiding collision methods are simulated and compared with each other. Some practical and effective methods of manoeuvring ships to avoid collision under different conditions have been obtained.
