本文提出了一种非对称系留拖缆模型，作为被拖船稳定拖曳性能的可行解模型。所采用的方法背后的基本思想是处理比采用典型拖缆模型1更好的拖缆稳定性。可能影响被拖船运动特性的几个拖曳参数，即，拖曳角和拖曳点位置的影响。非线性时域数值模拟结果表明，将拖航角增大到30 °，将拖航点从0.5移动到0.8，可显著减小不稳定被拖船的回转运动和拖缆张力，有效地提高其拖航稳定性。
This paper addresses an asymmetrical bridle towline model as a feasible solution model to stabilize towing performance of a towed ship. The basic thinking behind the approach adopted, is to deal with a better towing stability than employing the typical towline model 1 . Several towing parameters which may affect a towed ship motion behaviour i.e., tow angle and tow point position, are investigated theoretically. The nonlinear numerical time-domain simulation showed that the increase of towing angle up to 30 degrees and shifting tow point from 0.5 to 0.8 resulted in remarkable reduction in slewing motion of the unstable towed ship and the towline tension, which enhances effectively her towing stability.
