| 摘 要： | 为解决现有深水连接器连接性能研究中力学分析建模不准确,且缺乏抗弯抗扭能力分析的问题,基于ABAQUS有限元分析软件对深水连接器进行三维模型动态仿真分析,对连接器的受力、密封性能以及在实际工程需求中不同内压下的抗弯及抗扭性能进行深入研究。结果表明:在安装及生产两种工况下,深水连接器各部件除密封环外受力均满足其强度设计要求,密封环接触表面发生合理塑性变形,满足密封要求;随着内压的增加,深水连接器的抗弯能力逐渐下降,抗扭能力则呈现增加的趋势;极限弯矩分别在0 MPa与35 MPa内压下的判定依据为密封失效,在14 MPa与52 MPa内压下的判定依据为下毂座屈服,而极限扭矩在不同内压下的判定依据均为密封失效。

| Abstract: | In order to solve the problem of inaccurate mechanical analysis modeling and lack of analysis of bending and torsion resistance in the research of connection performance of existing deep water connectors, this paper is based on ABAQUS finite element analysis software for dynamic simulation analysis of 3D model of deep water connector, and for connector in-depth study of the stress, sealing performance and bending and torsion resistance under different internal pressures in actual engineering requirements. The results show that under the two conditions of installation and production, the components of the deepwater connector except the sealing ring meet the strength design requirements, and the contact surface of the sealing ring is reasonably plastically deformed to meet the sealing requirements; with the increase of internal pressure, the bending resistance of the deepwater connector is gradually decreased, and the torsional resistance is increasing. The ultimate bending moment is determined by the seal failure under the pressure of 0 MPa and 35 MPa respectively. The judgment basis under 14 MPa and 52 MPa internal pressure is the lower hub yields, and the ultimate torque is judged under different internal pressures. |
