Design and Research on the Two-Joint Mating System of Underwater Vehicle

摘要

In the 21st century,people have come to the era of ocean science and ocean economy.With the development of ocean science and technology and the thorough research on the ocean,underwater mating technique has been widely used in such fields as sunk ship salvage,deep ocean workstation,submarine lifesaving aid and military affairs.In this paper,researches are made home and abroad on mating technology.Two-joint mating system of underwater vehicle is designed including plane system,three-dimensional assembly system and control system in order to increase the capacity of adapting platform obliquity and adopting rotational skirt scheme.It is clear that the system fits the working space of underwater vehicle passageway and there is no interference phenomenon in assembly design.The finite element model of the system shell and the pressurization of the joint are established.The results of the finite element computing and the pressing test are accordant,and thus it can testify that the shell material meet the need of intension and joint pressurization is reliable.Modeling of the control system is accomplished,and simulation and analysis are made,which can provide directions for the controller design of mating system of underwater vehicles.
