摘　　要：深水连接器是连接海底管道的重要工具,而锁紧机构是连接器的重要组成部分,我国深水锁紧技术还处于空白阶段。通过对设计过程中的难点进行分析和总结,形成了锁紧机构的设计方案,并对关键技术和难点做了归纳和总结。连接器锁紧机构可以在1500m水深、油气压力为5000psi条件下实现对6英寸管道锁紧和解锁的功能。通过ADAMS和Abaqus对其进行了运动学仿真和复杂工况下的强度分析,得出锁紧机构的所能承受的最大弯矩、扭矩和拉压力,并通过运动学仿真验证了锁紧和解锁过程中无阻滞现象,进一步验证设计的合理性,为其液压系统设计及样机的研制提供了理论依据。The locking mechanism is one of the important parts of the deep-water connector, which is a significant tool for connection of deep-water submarine pipelines, and deep-water lock technology in our country is still blank. Based on the difficulty in the design process analyzed and summarized, it formed the scheme of the locking mechanism and made the induction and the summary of the key techniques and difficulties. The connector locking mechanism can realize the 12 inches pipe locking and unlockingfunetian in the conditions of 1500m depth of water, oil and gas pressure for 5000psi. Based＇on the kinematics simulaation and strength analysis with ADAMS and A baqus in complicated conditions, maximum bending moment, torque, pressure and tension that locking mechanism can withstand has been got, and no bloeking phenomenon has been also verified in the locking and unlocking process through the kinematics simulation, which further proves the rationality of the design and provides a theoretical basis for the hydraulic system design and the prototype development.
