The Research on Shell Strength and Pressurize Reliability of Underwater Vehicle Mating Device

Underwater vehicle has abroad applications in submarine rescue and deep-ocean workstation and so on. Moreover, mating device strength and skirt mouth pressurize is important condition for working safe. In order to realize reliable mating, endure force analyzing on steady mating to platform was put up and load to finite element model. The computing result of finite element model and experimental value is accordant. The research and experiment on pressurize methods was finished, the result show that O-type pressurize and lip-type pressurize has ensured pressurize reliability. This paper can provide reference for analogy structure Strength and pressurize reliability.
