摘　　要：为了探究船舶在拖锚运动过程中的动态特性,本文通过数值仿真方法对船舶拖锚运动过程进行仿真。基于直接积分法,建立锚链拉力的计算模型,并结合分离型建模理论,建立船舶三自由度拖锚运动数学模型,并以“北斗”轮为研究对象,对拖锚运动数学模型进行拖锚漂航仿真,通过与“北斗”轮实船试验结果的对比验证可知,本文的模型化方法能够反映船舶拖锚运动时的三自由度运动过程,可以准确地模拟船舶拖锚运动过程。In order to investigate the dynamic characteristics of the ship in the process of anchor dragging motion,this paper simulates the anchor dragging motion process of the ship by numerical simulation method.Based on the direct integration method,the calculation model of anchor chain pulling force is established,and combined with the separation type modelling theory,the mathematical model of the ship's three-degree-of-freedom anchor dragging motion is established,and the mathematical model of the anchor dragging motion is used as the object of the study,and the anchor drifting simulation is carried out on the "Beidou" ship,and the modeling method can reflect the three-degree-of-freedom motion process of the ship during anchor dragging motion,and can accurately simulate the ship dragging motion process.Through the comparison and verification with the real ship test results of the "Beidou" ship,it can be seen that the modelling method in this paper is able to reflect the three-degree-of-freedom motion process of the ship's anchor-dragging motion,and can accurately simulate the ship's anchor-dragging motion.
