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.
為研究單錨泊船在較彊榦涉力(風、流)作用下產生的偏盪運動,利用分離型建模思想,建立瞭錨泊船運動的數學模型,併利用Matlab對單錨泊船的偏盪運動進行倣真,得齣船舶在偏盪以及走錨時的運動形態和各運動參量的變化趨勢,進而得齣船舶在風流中保證安全錨泊的齣鏈長度的計算公式,可為船舶駕駛員的錨泊操縱提供參攷.

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.
