摘要
退抛法一直是大型船舶抛锚采取的主要方法,在整个抛锚作业过程中船长不仅要对船舶的余速进行判断、限制,还要根据所在水域的水深施放锚链。论文基于悬链线理论,对船舶、锚链进行受力分析,通过Matlab对算例进行模拟仿真,得出了关于水深、船舶余速、锚与锚链对船舶的牵制力以及船舶对锚链的拉力之间的关系。并以此为基础,只要提供船舶型线图、锚型、锚重以及锚抓力系数就可求出船舶抛锚所允许的最大余速、锚与锚链对船舶的牵制力和船舶对锚链拉力,为船舶安全锚泊提供了有力保障。
Thrown back method has always been the main approach to large ships anchored. During the whole anchoring operation,the captain must not only judge and limit the remaining speed of the ship,but also apply the anchor chain according to the wa-ter depth of the water area. In this paper,based on the catenary theory,analysis on ships,the stress of the anchor chain of the exam-ple simulation by Matlab simulation are obtained about water depth,leaving velocity,anchor and chain contain power for ships andvessels on the relationship between the tensile strength of the chain.And to this as the foundation,as long as you provide the shipchart,anchor,the anchor heavy and anchor holding power coefficient can be calculated when the leaving velocity allowed by theship anchored,anchor and anchor chain to contain power and ship to anchor chain,for the ship safety anchorage provides a powerful guarantee.
