舷侧艏锚锚链摩擦外板问题分析

Analysis of friction between bow anchor chain of shipboard and outside plating

某型小水线面双体船采用舷侧出锚,在开放海域内抛锚后,船体随风浪漂移,从而引发锚链与船体外板摩擦。文中利用悬链线方程并结合图示详细分析了此类问题的起因,分析得出最优解决方案,从而有效避免后期类似问题的发生,较好地提高了船舶使用性能。

Since a certain type of SWATH is anchored from the shipboard, its outside plate rubs against the anchor chain due to the drift of ship hull in the wave when the ship is anchored in the open sea area. This paper detailedly analyzes the cause of this problem through the catenary equation together with illustration, and proposes an optimized resolution in order to effectively avoid similar problems, which can greatly improve the ship performance.
