针对密封结构的密封压力水平这一海底管道维修管卡的关键性能问题，本研究采用三维模型分析，以更精确地模拟复杂管卡密封结构密封建立的实际过程。相较于二维轴对称模型分析，三维模型能够全面展现所有密封接触面的接触压力分布情况。本研究中，针对一款采用氟橡胶密封件的全结构管卡样机，建立了一套对管卡密封结构进行三维仿真分析的方法，分析了两种硬度组合的密封件条件下，各密封面接触压力的大小及分布情况，从而确定了密封结构的薄弱部分，并分析了密封件硬度对接触压力的影响。然后，通过管卡样机测试，得到了相同硬度组合密封件下管卡的密封压力，并与仿真结果进行了对比验证。分析结果显示：密封条与密封圈之间的接触面两侧为管卡密封的最薄弱部分，其次为两瓣密封圈之间的接触面；在最薄弱部分，接触压力的大小及其变化趋势同测试密封压力基本一致；相同密封圈压缩量下，硬度较高的密封件组合能够产生更大的密封压力。
Abstract：Regarding the key performance issue of repair clamps for subsea pipeline, which is the sealing pressure level of the sealing structure, 3D model is employed to more accurately simulate the actual process of sealing establishment for complex clamp seal structure. Compared to the 2D axisymmetric model analysis, the 3D model can comprehensively display the contact pressure distribution of all seal contact surfaces. This paper establishes a 3D simulation analysis method for the seal structure of a full-structure clamp prototype using fluorine rubber as the material of seal components. The magnitude and distribution of contact pressure on each seal surface under two different hardness combinations of seal components were analyzed, and the weak parts of the seal structure were identified. The influence of seal component hardness on contact pressure is also analyzed. Then the sealing pressures of the repair clamp under the same hardness combination seals were obtained through the testing on the clamp prototype, and compared and verified with the simulation results. The analysis results indicate that both sides of the contact surface between seal strip and seal ring is the weakest part of the clamp seal, followed by the contact surface between two seal rings. At the weakest part, the magnitude and the changing trend of contact pressure and test sealing pressure are basically consistent. The combination of seals with higher hardness under the same seal ring compression has a higher sealing pressure.
