The Design And Simulation Analysis Of Hybrid Underwater Glider

Hybrid underwater glider is administration underwater vehicle (AUV) and underwater glider (UWG), which is integrating the strongpoint of both, mainly used in the detection of the Marine environment. Under the mode of AUV, rely on the propeller quick navigation can come true, it has the advantage of good maneuverability, fast response speed, positioning and tracking precision. In the glide mode, it is energy saving, high efficiency, through the buoyancy driven system it realized own net buoyancy of the cyclical changes and gliders longitudinal gliding movement; Through the attitude control system to implement the periodic change of center of gravity position, realize the gliders navigation of pitch and roll attitude correction.In this paper, we study the hybrid of underwater glider is mainly used in ocean thermo cline profile survey, the first reference to existing products and target function, the complex gliders system for modular processing, design the overall layout of gliders mechanical system and control system of the overall layout. Second glider pressure-tight shell for the detailed design and calculation, and by using the finite element analysis software ANSYS, the most dangerous period of the pressure hull strength analysis and buckling analysis, validate the design of pressure characteristics and bearing performance of pressure hull. Then the navigation system of the glider (including buoyancy driven system, attitude control system and propeller propulsion system) is analyzed and designed, the control system of glider are analyzed and studied the attitude control system of PID control and simulation analysis. Finally, the optimization design was carried out on the wing of the glider, provided by CFX fluid analysis software to optimize wing before and after the contrast analysis, verify the hydrodynamic characteristics of the optimized airfoil has better.
