摘要
为探索锚泊船偏荡时船与锚链相互作用问题,开展了非均匀条件下锚链静力特性的快速计算研究。采用分段外推-校正方法计算了锚链张力、顶端倾角、悬垂线形状及长度。通过寻找锚链悬垂线最低点位置以及预估顶端倾角的方法来增加求解速度,实现了快速运算。
A rapid computing method of the static performance of anchor chains under the conditions of uneven current and weight is developed so as to further explore the interaction between the ship and mooring chains.The tension,top end angle and, the shape and length of the sag of an anchor chain are calculated with piecewise extrapolating method.The rapid computation is realized by means of searching the lowest point of the chain and predicting the top end angle of the chain.
