Design And Research Of A New Bionic Wave Energy Glider

In recent years,as people continue to explore the ocean,buoys,submersible beacons,wave energy gliders and other marine environmental observation platforms have gained widespread attention,of which wave energy gliders are a new type of mobile marine observation platform that has developed rapidly in recent years.It has the advantages of low noise,low cost,good stealth,long range,energy saving and environmental protection,easy to remote control,etc.,and has been widely used in marine investigation,exploration,monitoring and military industry.In this paper,a new bionic wave energy glider based on a shark pectoral fin bionic hydrofoil and a catamaran-like surface mother ship is designed by combining bionic technology and numerical simulation.The main research work is as follows:(1)The motion principle of wave energy glider is systematically explained,the stability simulation of monohull type surface mothership and imitation catamaran type surface mothership is carried out by AQWA software,the selection of surface mothership is completed and the 3D modeling of surface mothership is carried out by Solidworks software,and the finite element analysis and navigation resistance analysis of surface mothership are carried out.(2)Bionic design of hydrofoils and airfoils based on shark pectoral fins,and design of keel main frame,hydrofoil mounting hole spacing and rotating bearings of the underwater tractor by CFD simulation to complete the overall structural design of the underwater tractor.(3)Designing a reliability verification scheme,conducting fluid-structure coupling analysis,fatigue analysis and modal analysis for the surface mothership and the underwater tractor respectively to verify their structural reliability under the extreme motion condition.
