【摘要】 为研究单锚泊船在较强干涉力(风、流)作用下产生的偏荡运动,利用分离型建模思想,建立了锚泊船运动的数学模型,并利用Matlab对单锚泊船的偏荡运动进行仿真,得出船舶在偏荡以及走锚时的运动形态和各运动参量的变化趋势,进而得出船舶在风流中保证安全锚泊的出链长度的计算公式,可为船舶驾驶员的锚泊操纵提供参考.更多还原

【Abstract】 To study yawing of an anchored ship in strong external forces such as wind and current,a mathematical mode of the anchored ship’s movement was developed based on mathematical model group(MMG),and yawing movement of the ship at a single anchor was simulated by using Matlab simulation program. The ship’s motion and trend of each motion parameters under different situations were put forward. Furthermore,the formula for the necessary length of chains to be computed was concluded,which can provide references for ships’ officers when carrying out anchoring operations.更多还原
