Study on Key Technologies of Neutral Buoyancy Underwater Manipulator
The underwater manipulator can provide position transfer and support for neutral buoyan-cy training,thus improving the consistency and efficiency of the training process.With regard to the three key technologies of underwater sealing,neutral buoyancy leveling and anti-corrosion,a techni-cal solution using multiple redundant seals,integrated design of shaped buoyancy shells and joints was proposed,and titanium alloy and duplex stainless steel were selected to enhance the anti-corro-sion performance.The underwater manipulator has been used in training for over two years with good working condition,and with a continuous usage up to 226 days,which ensures the quality and effec-tiveness of the underwater test.
