摘　　要：求解锚链对船舶的水平作用力时对悬链链型区分为自悬链和约束链两种情况并采用了不同的计算方法,计算锚的抓力系数时考虑了锚在海底移动距离、锚杆仰角、锚型、底质等因素,提出了锚在海底移动的运动方程。分别计算了锚的运动和船体的运动,运用MMG(Ship Manoeuvring Mathematical Model Group)模型,建立了比较符合抛起锚操纵实践的船舶抛起锚操纵运动数学模型。编制相应的软件进行仿真试验,试验结果和相关文献的结果一致。Two different methods are applied in the conditions of self-suspending chain and constrained chain respectively when calculating chain horizontal force. The anchor shift distance, pole elevation, type and quality of seabed are taken into account when calculating anchor holding power coefficient. An anchor motion equation is given. The motions of anchor and hull are calculated separately. By applying MMG（Ship Manoeurring Mathematical Model Group） model, a mathematical model of ship maneuvering motion at dropping and lifting anchor is established, which is more suitable for practical motion. The program of calculation is written and the simulation tests are carried out, and the results are in good agreement with that of related literatures.
