Research on the mechanism of efficient motion of full-ocean depth self-deformable underwater vehicle
Different from the conventional underwater vehicles,full-ocean depth underwater vehicles face a vertical depth over 10000 meters.At present,the diving and floating process of full-ocean depth underwater vehicles take up most of the time after entering the water,which resulting in inefficient of them.In this paper,based on the analysis of diving and floating process mode and low resistance configuration mode,combined with the design idea of variable structure underwa-ter vehicle,we construct an efficient motion mode which are suitable for horizontal and vertical plant,propose the imple-mentation of self-deformable underwater vehicle for the full-depth ocean.Based on the modeling and analysis of the motion mechanism of the underwater vehicle in the diving and floating process and the direct route stage,we propose an evaluation method of motion efficiency based on effective working time.Finally,combined with the identification of the resistance coefficient by the fluid simulation software Fluent,the efficiency of the self-deformable underwater vehicle is evaluated,which verifies the efficiency of the self-deformable configuration mode is compared with the traditional rotary configuration mode in the full sea depth working environment.
