The wave energy glider is a new type of instrument for carrying out the marine environment investigation,it consists of the floating platform,connecting cable and underwater traction.It can be converted into the driving force along the surface of the water when the amplitude of waves and particles under water particle between the deep difference generated by the wave energy,so as to realize in the marine environment survey operations without other energy supply.Because of its low noise,low cost and reliable operation,it is suitable for many monitoring instruments to carry,and easy to remote control,etc.,and has a broad application prospect in the future marine survey.At the same time,the wave energy glider has some technical difficulties,because the existing wave energy conversion efficiency is low,so that the wave glider can only sail at a low speed.Therefore the design of a wave energy absorption and conversion capacity,small resistance,applicable to a variety of sea conditions and has a relatively high strength of the new bionic wave energy conversion system,to improve the wave glider operation ability,reduce the cost of marine investigation,plays a vital role.In this paper,the bionic optimization design of the existing wave glider is carried out,and the numerical simulation analysis and structural reliability verification are carried out.In this paper,through theoretical analysis of micro amplitude wave wave glider wave energy absorption principle,in accordance with the common goal of the sea sea data,theoretical calculation of the wave amplitude difference in potential theory and other related data,so as to construct the overall system parameters of bionic wave glider model.In this paper,a new type of bionic hydrofoil with a new wave energy glider is proposed,which is based on the flapping wing shape.Comparing a variety of common hydrofoils,combined with FLUENT fluid simulation technology and ANSYS fluid-solid coupling technology.The dynamic characteristic curve under different water reference variables and drawing;the structure design of bionic surface wave glider floating body,and the material design and strength calculation.And the reliability analysis is carried out in extreme sea conditions.
