中文摘要:
      深海油气田水下生产系统装备之间的精准连接是国际公认的技术难题,对接一般通过深海连接器完成。弹性夹头是水下连接器的重要组成部分,其性能关系到海洋油气生产系统的安全性和可靠性。弹性夹头的主要作用是在水下机器人的辅助下连接和锁紧连接器的固定端和移动端。采用ABAQUS软件的显式动力学分析模块计算夹头夹紧心轴这一过程中的应力、反作用力状态。三维模型仿真结果表明,锁紧过程中弹性夹头的最大应力不超过430 MPa,小于所选取的材料屈服强度480 MPa。采用正交试验和方差分析的方法研究夹头的长度、夹头与心轴的间隙等几个关键尺寸从而分析影响夹头应力和连接所需推力的最显著因素。对夹头的结构进行优化设计,同时也为夹头心轴结构的设计提供了理论依据。最后,通过试验研究对样机进行测试,测试结果表明,夹紧动作所需的最大推力在700 N以下。
英文摘要:
      Precise connection of equipment between subsea production systems in deep-sea oil and gas fields is an internationally recognized technical challenge. Docking is generally accomplished through deep-sea connectors. The elastic chuck is an important component of the underwater connector, whose performance is related to the safety and reliability of the offshore oil and gas production system. The main function of the chuck is to connect and lock the fixed and mobile ends of the connector with the assistance of an underwater robot. The explicit kinetic analysis module of the ABAQUS software is used to calculate the stress and reaction state of the collet during the process of mandrel clamping. The results of 3D model simulation show that the maximum stress of the elastic chuck during the locking process does not exceed 430 MPa, which is less than the yield strength of the selected material of 480 MPa. 3D model simulation is used to derive the required thrust force provided by the underwater robot, which can provide a basis for the selection of the robot in actual work. Orthogonal experiment and analysis of variance are used to study several key dimensions such as the length of the chuck and the gap between the chuck and the mandrel, so as to analyze the most significant factors affecting the stress of the chuck and the thrust required for connection. According to the results, the structure of the chuck is optimized, and it also provides a theoretical basis for the design of the chuck spindle structure. Finally, the prototype is tested through an experimental study, and the test results show that the maximum thrust required for the clamping action is below 700 N.
