顶张式立管液压连接器密封结构承载能力分析
|
摘要
针对500 m水深顶张式立管,设计液压连接器模型,对拉、压、弯等各种受力状态进行分析,提出液压连接器密封结构在拉、压、弯等状态下可承受最大载荷的计算方法。液压连接器密封结构可承受的最大拉力取决于锁块危险截面的强度和锁块的伸长量;可承受的最大压力取决于金属密封圈的抗压强度与结构参数;可承受的最大弯矩取决于受拉最严重的锁块和受压最严重的金属密封圈部分。对液压连接器密封结构承载能力的分析,有助于对液压连接器整体承载能力的分析研究。
The model of hydraulic connector is built for the top tensioned riser for 500 meters water depth. Tension,pressure, and bending moment are analyzed, and the method of maximum load calculation is proposed. The maximum tension of the hydraulic connector seal structure is determined by the strength of the dangerous section and elongation of the locks. The maximum pressure is determined by the compressive strength and structural parameters of the metal sealing ring. The maximum bending moment is determined by the most severe lock and the most pressing metal sealing ring. The analysis of the bearing capacity of the hydraulic connector seal structure is helpful for the analysis of the bearing capacity of the hydraulic connector entirety.
