In order to explore the mechanism of wave energy acquisition and efficient conversion,according to the movement characteristics of birds in nature and based on the wave energy acquisition theory of oscillating flapping wing,a discrete wave energy conversion system of oscillating flapping wing based on multi chamber cylinder is proposed,and its hydraulic conversion system is designed and analyzed.Wave energy acquisition and conversion is a stochastic dynamic process of multi physical field coupling,and its energy conversion efficiency and stable output are two crucial factors.According to the different mechanical components used in the energy conversion system,it can be divided into pneumatic,hydraulic,mechanical transmission and special motor.This paper selects the hydraulic conversion system of the oscillating flapping-wing wave energy power generation device as the main research object,establishes the overall analysis model of the wave energy conversion device,designs and analyzes the wave energy acquisition system and the hydraulic conversion system,studies the control strategy of the system,and combines virtual prototype simulation,exploring the optimal design scheme of the new wave energy conversion system,revealing the relationship between system functional performance and design parameters,and providing theoretical basis and simulation experimental reference data for the integrated design of such complex multi-body dynamics systems.The virtual prototype model of wave energy acquisition and conversion system is established by using AMESim simulation software.The multi field coupling characteristics in the process of flapping wing energy acquisition are studied,the actual wave excitation characteristics are simulated,the output performance of the system is verified,and the influence of component parameters and wave conditions on its dynamic performance is studied.At the same time,compared with the common system,the advantages and disadvantages of the design scheme are analyzed.In order to achieve the best match between the output force of the multi cavity cylinder and the wave characteristics,the valve group control mode and expert rule table of the corresponding hydraulic system are established,the wave energy adaptive acquisition theory is explored,and a stable and efficient wave energy power generation system is developed.
