张力腿平台筋腱连接器的结构设计

针对500 m水深张力腿平台实际尺寸及载荷要求,设计一种适用于40 in筋腱的筋腱连接器。顶部连接器通过抱夹卡瓦与筋腱连接,底部连接器采用旋转式锁紧机构,两者通过柔性体来提供柔性连接。柔性体采用14层钢板及15层橡胶的设计,可以在承受1 458.8kN·m转矩的同时,实现最大12°的转角。抱夹卡瓦选用10mm间距及40°夹角的卡环,可以与筋腱稳固啮合。仿真结果表明,采用现有材料的柔性体和抱夹卡瓦均满足Survival海况的使用条件,为我国首座TLP平台的筋腱设计提供了可靠的解决方案。

Structure Design for TLP Tendon Connectors

For the actual dimensions and loading requirements of the tension leg platform (TLP) with 500 m water deep, a tendon connector which is suitable for the tendon of 40 in is designed. The tendon top connector (TTC) connects to the tendon by the latching segment. The tendon bottom connector (TBC) adopts the rotary locking mechanism. The two parts connect through the flex joint. The flex joint is using 14-layer steel and 15-layer rubber design that can support 1 458.8 kN?m torque, while achieving a maximum of 12° angle. Using latching segment with a 10 mm pitch and 40° angle clasp can ensure a strong engagement with the tendons. The simulation result shows that the flex joint and the latching segment with the existing material meet the demand of the survival condition, which offers a reliable solution for the tendon design of the first TLP in China.
