本文针对塔架软刚臂单点系泊系统与船体的相互耦合运动展开研究，采用ADAMS对软刚臂系统多自由度运动特性进行预测分析。分析发现，当船体横向运动时，软刚臂系统刚度和纵向时的变化趋势是一致的，相同位移下，其数值远小于纵向运动时的刚度。随着船体正向运动位移的增加，2条系泊腿的姿态逐渐不同，左系泊腿随着软刚臂自转，出现向上翘起，张力大于右系泊腿。通过船体纵向运动碰撞分析发现，船体靠近导管架8.19 m时，软刚臂与船船首甲板发生碰撞，其碰撞力达到8 251 N，这有利于对系泊系统进一步优化设计。
This paper makes a research on the coupled motion between Tower Soft Yoke Single Mooring System and ship, predictive analysis on multiple degrees of freedom motion characteristics for Soft Yoke Mooring System based on ADAMS. The results revealed that when ship moved transverse, the variation trend of Soft Yoke System stiffness is similar with lengthwise. The magnitude of stiffness is smaller than lengthwise under the same displacement. The attitude of two pendants is different as the increase of ship motion displacement. The left pendant gradually turned up after Yoke revolved on its own axis. The tension of pendant was larger than right one. Yoke collided with ship from the ship collision analysis when ship is 8.19 m near jacket. The collision force reached 8 251 N. This is beneficial for Single Mooring System optimization.
