Wave energy has the advantages of environmental protection,abundant reserves and renewable,and it is highly valued.The swing wave power generation technology has the advantages of wide frequency response,high energy conversion rate,and strong anti-wave impact,And its practical value and commercial value are reflected in the course of research.the research and development of this technology is relatively backward in China.Therefore,it is particularly important to independently research and develop the wave type wave power generation technology in accordance with the actual situation of China's oceans.In this paper,the wave motion process is analyzed by using linear wave theory,And the theoretical basis of swing wave power generation technology is also studied.Aiming at the instability of the traditional swing wave power generation device during its working process,a power generation test scheme using four level energy conversion is proposed.In the process of energy conversion,hydraulic energy conversion links are added.A swinging wave power generator is designed by using modern design method,and its working principle,main structure and working process are studied.Secondly,based on the dynamic relationship between the oscillating body and the seawater,a mathematical model of the energy conversion of the oscillating body is constructed.The natural frequency,damping ratio,maximum oscillating angle displacement and energy conversion efficiency of the device are studied.The overall structure and key parts of the pendulum body are designed and analyzed by adopting the theory of mechanical design.Using the combination of theoretical analysis and numerical simulation,the force and movement characteristics of the vertical and left limit positions of the swinging body of the power generation test device were studied analysis.Afterwards,the dissertation focuses on the role of hydraulic system in the process of energy conversion,studies the composition and working principle of hydraulic transmission system,and studies the working performance of hydraulic pump,hydraulic motor,hydraulic accumulator,check valve and caisson.Based on this,the power,efficiency and torque characteristics of the entire hydraulic system are analyzed.Finally,the dissertation studies the energy conversion performance of the oscillating wave power generation tester during power generation,analyzes its energy conversion system model,and studies the system response characteristics of the test device,and then studies the wave power generation test device based on MATLAB software.The power generation and swing mass,width,wave period,and wave height affect power generation.
