Research On Underwater Mating Key Technology Of Manned Submersible

Rescue bells and deep submergence rescue vehicles are main manned submersibles to resuce large underwater carriers. Their key technology is the underwater mating, which is fundamental guarantee for transferring personnel and material between an underwater carrier and a surface ship. A wrecking alarm buoy is the important factor to influence the time limit to search a wrecking large underwater carrier and the mating rescue ability of rescue bell.With a view to the problems of wrecking alarm buoy emerged in use, a method studying on its dynamic features is brought forward, which is adding dynamic loads on static balance and has been proved by comparing its calculating data with previous reliable literature data. The floatage state and Load rule of the buoy is analyzed. The causes are found of the buoy submersing in seawater, the alarm light signal ghosting and the buoy cable breaking off. Some ideas are put forward in order to solve the buoy problems.A method is brought forward which is used in analyzing the underwater mating ability of the rescue bell in sea current. And the ability is analyzed. The causes are discussed of the downhaul cable breaking off, mating seal failing, and breaking away sluggish. Some improvement measures and mating manoeuvre suggestions are put forward. The mating ability and security has been observably increased afer adopting manoeuvre suggestions.A method is brought forward which is used in analyzing the underwater mating ability of the deep submergence rescue vehicle in sea current. And the ability is analyzed. Some improvements measures are put forward for the new deep submergence rescue vehicle. A method evaluating the pilots'operation skills based on fuzzy synthetic evaluation theory is brought forward. And it is verified by the tests applied in the pilot candidates in 2008.Based on virtual reality, a steering voyage simulation system of the deep submergence rescue vehicle is designed. Employing the hydrodynamic wing theory, the hydrodynamic equations of the shroud is brought forward and solved. The underwater motion equations of the submersible are improved according to opration experience. Some clear outside virtual scenes are developed which may be seen by pilots with the help of video cameras. The theory analysis of mating ability is verified by the tests running on the simulation system.
