摘　　要：本文建立了风浪中拖航系统(包括拖船—拖缆—被拖船)的操纵性运动的数学模型 ,并以1940kw拖船与8820t甲板驳以及15760t半潜驳为例 ,分析了航速、缆长、载重量、纵倾和环境条件对拖航系统的运动与拖缆力的影响。In this paper, a mathematical model of towing system's maneuvering motion in wind seas is established. The towing system consists of a tug, a towline and a barge. By using this mathematical model and taking 1940 kw tug - towline - 8820 t deck barge system, as well as 1940 kw tug - towline - 15760 t semi-submersible barge system as examples, the influence of those working parameters, such as towing speed, towline's length, deadweight, trim and environmental conditions on the straight-line motion of towing system, and towline's tension is analyzed.
