Structural Design and Simulation of Underwater Vehicle for Ship Inspection
In view of the low efficiency of traditional manual ship inspection and the problems of large personal safety risks,combining the application scenario of ship inspection and underwater vehicle technology to study and design a ship inspection underwater vehicle to replace people to carry out underwater inspection of ships.First of all,the ship inspection underwater vehicle adopts the frame structure design,which greatly improves the anti-current ability of the machine.Secondly,the ducted propeller is designed as the propulsion structure to improve the sensitivity of underwater operation.Finally,the relationship diagram between velocity and resistance obtained by the fluid simulation of the structure shows that the vehicle has less resistance and higher sensitivity in underwater operation.The experimental results show that the vehicle can detect the underwater part of the ship before sailing,which can not only reduce the difficulty of ship inspection,but also improve the efficiency of ship inspection.
