摘 要: 利用分离型建模思想,对单锚泊船在风作用下产生的偏荡运动进行研究,建立锚泊船运动的数学模型;利用Matlab软件对单锚泊船的偏荡运动进行仿真,得出船在风中偏荡运动的形态,并分析出船舶在不同链长、装载状况、不同风速下偏荡幅度和锚链最大张力的变化趋势;同时,也对单锚泊的极限风速进行估算分析。结果表明:风力较强时单锚泊已不足以保证锚泊船安全。
关 键 词: 水路运输;单锚泊;偏荡;出链链长

Abstract: This paper studies on slewing motion of a single anchoring ship in wind force by separation modeling and established the mathematical model of a single anchoring ship's slewing movement. The slewing movement of the single anchoring ship was simulated by using Matlab simulation program, the ship�s slewing motion in wind and trend were put forward; the trend of transverse range and maximum chain force under different chain length, load and wind speed was analyzed; meanwhile, the limited wind speed at single anchoring was also analyzed. The results showed that the single anchoring couldn't ensure the safety of the ship in strong wind, which can provide references for anchoring operation.
Key words: waterway transportation; single anchoring; slewing; length of let-go chain
