中文摘要：
浅水软刚臂作为单点系泊方式的一种,在长期的交变荷载作用下会产生疲劳问题。根据浅水软刚臂形式的特点,确定监测信息,设计监测方案。在实际监测中发现,软刚臂结构会发生垂直于船体的横向摆动现象。基于第一类全椭圆积分,建立了软刚臂在大幅度摆动下的横摆理论方程。采用TLD子结构模型试验的方法,对软刚臂减振进行了初步的研究。结果表明,采用适当的水深和重量进行TLD调制,对软刚臂减振效果可达80%以上。
英文摘要：
Soft yoke mooring system（SYM）,one kind of single point mooring system,would be occurred a fatigue problem during long period alternating loads.According to the characteristics of soft yoke mooring system in shallow water,the monitoring information was determined and designed.In the monitoring process,the phenomenon of transverse-oscillation of SYM was found.Based on the first complete elliptic integrals,theory equation of Transverse-Oscillation in a considerable angle was constructed.Using the method of the TLD substructure model test,dynamic vibration absorbing for the SYM was studied.The experimental result shows that,the effect in vibration control can be reached more than 80% by adjusted the appropriate depth and weight of TLD model.
