In a social environment with rapid economic development and rapid development of science and technology,only relying on traditional and non-renewable energy to generate electricity can not meet the needs of people,so the exploitation and utilization of new energy is extremely urgent.Oceanic energy,one of new energy,is not only renewable but rich in it,so it's very meaningful to study oceanic energy for alleviating energy shortage and maintain the sustainable development of society.In this paper,considering the current research status of wave power generation devices and the sea area situation in our country,a water and gas integrated sea wave generator of push plate capsule type was designed.the device not only can use the motion of the waves to generate electricity but also can take advantage of the gas in water to conversion to electric energy.And mainly based on resonance principle,it can make the energy capture device to absorb the energy of the waves more fully,promoting the efficiency of its power generation further.Firstly,the development of sea wave power generation at home and abroad was introduced,enumerating relatively mature sea wave generators and expounding its principle.Various sea wave generators were summed up,and their principle were expounded,at the same time their merits and demerits were generalized.On the basis of this,a sea wave generator adopting resonance principle-a water and gas integrated sea wave generator of push plate capsule type was put forward.Its ingenious design of water and gas integration improved the conversion efficiency of wave energy to electricity.Secondly,the 3D model was conducted by SolidWorks,and the overall structure of the power generation device was designed.The folding plate structure was specially designed in it.For one it can adjust the amplitude of the power generation device,for another the linear permanent magnet generators on both side of it can also generate electricity.All above make the wave energy utilized more fully.Thirdly,the wave force of the vibration system was solved according to the theory of linear microamplitude wave and the F-K hypothesis method,getting the wave forces in the horizontal direction of push plate.The vibration system was modeled and its mathematical model was carried out,obtaining the natural frequency and the main vibration modes of each order.Then,the matrix transformation was done by the method of D-H.After that,Lagrange dynamic equation was established based on generalized coordinates.The dynamic simulation of vibration system was done by ADAMS,getting the law of motion of folding plate by the results.And the reasonableness of the equivalent model was verified by ADAMS.Finally,the vibration analysis of the vibration system was done,getting the steady state solution of the vibration system,the stiffness coefficient k and the damping coefficient?,formulating the spatial equation and the transfer function.And the transfer function was simulated using MATLAB,obtaining the amplitude-frequency response curve of vibration system.According to the simulation results,relation of amplitude and frequency of the vibration system can be obtained visually,so is the vibration frequency.
