Characteristics and Experimental Research on Performance of the Seal Structure of Deepwater Collet Connector

The sealing reliability of collet connectors is essential within underwater production systems. This paper based on the lens gasket mechanism and Hertzian contact theory, establishing mechanical models for core components in preloaded working states analyzing minimum required axial preload force sealing. According to principles connector, characteristics each element are analyzed both states. interplay forces between these elements subsequently determined. Furthermore, amplification structure confirmed through simulations characteristics. Finally, accuracy theoretical simulated results experimental validation.
