Research on the Construction Strength and Pressurize Capability of Two-Joint Mating System of Underwater Vehicle

With the development and researching more on the ocean, underwater mating technique has been widely used such as ocean workstation, aid submarine lifesaving and military affairs field. In this paper, in order to increase capacity of adapting platform obliquity and adopting rotational skirt scheme, two-joint mating system of underwater vehicle was designed including three-dimension assembly design and control system. It is indicated that the system can meet working space of underwater vehicle passageway and there is not interference phenomenon by assembly design. The finite element of system shell and pressurize of the joint was established. The computing result and pressing test is accordant, thus it is testified that the shell material can meet strength need and joint pressurize is reliable.
