Overall design and performance analysis of deep-sea ROV

Facing the needs of deep sea equipment maintenance work.The research on overall modular design for deepsea working robots is carried out based on the SolidWorks virtual design The strength and the stability of the pressure bearing members of the robot are analyzed based on the FEM and the empirical formula to realize the lightweight design with satisfactory structural strength.The viscous flow theory based investigations on the resistance performance of the robot in forward and downward motion are carried out as the guidance for the design and selection of the propulsion system.The analyze results of the robot properties show that the structural performance of the robot could meet the requirement of operations under 1200 meters water depth.Meanwhile,the configuration and the thrust of the propulsion system could meet the requirement of the robot navigation at the design velocity.The modular design method proposed in this paper effectively improves the efficiency of the robot design.
