摘　　要：目前多船辅助定位的拖航作业主要依靠船长的经验,尚无一套有效的控制手段。因此在多船协调作业时,很难实现准确的多船辅助定位。探讨多船辅助定位的拖航系统操纵性的计算方法,对船舶拖航作业系统进行操纵运动的模拟具有一定的现实意义。以MMG分离式操纵性数学模型为基础,结合拖缆的悬链线模型,在考虑各种环境因素的条件下,建立了一个比较完整的拖航系统的操纵性数学模型,通过编制的可视化仿真程序,真实模拟了拖航系统在风、浪、流以及浅水域中的三自由度的操纵运动。Presently, control method for towing system of multi-ship auxiliary positioning is not available. The control of towing system mostly depends on the experience of captain. In the multi-ship operations, it is hard to achieve accurate multi-ship auxiliary positioning. Thus, the calculation for towing system of multi-ship auxiliary positioning and the simulation of ship towing system has some practical significance. Based on the MMG＇s separated modeling theory, and the catenary model of towed cable, a 3-DOF manoeuvring model of towing system which consists of towing ship and towed ship connecting with cable was established, and the effects of wind, wave, current on the towing system was considered. With this model, the 3D numerical simulation program of towing system was made, and the prediction of maneuvering motion of towing system was realized.
