In recent years,the irrational world energy structure has become increasingly apparent,especially the rapid development of industry corresponding to the energy reserve and environmental pollution caused by the rapid consumption of energy.The successful reform of the energy structure has become the key to future sustainable development.Furthermore,China's proposal to build a Silk Road and a community of marine destiny has increased the frequency of maritime activities,and the importance of marine resource development has also increased.Based on the reality of wave energy resources in China 's offshore waters,this topic analyzes a wave power generation system suitable for China 's offshore waters.This system has the characteristics of less freedom and uses the principle of resonance to convert the wave energy in several directions of the waves.High-efficiency conversion power generation.Firstly,the resource distribution of wave energy at home and abroad and the development of domestic and foreign wave power generation system technologies are introduced.Based on this,the research and application of the most widely used typical wave theory are introduced,the basic equations and formulas of the micro-amplitude wave theory are described.Meanwhile,the conversion is calculated in conjunction with the Froude-Krylov assumption.The wave force of the high-efficiency cylindrical float has obtained the simulation results of the draught,vertical displacement and wave force of the float.At the same time,the hydrodynamic analysis of the float based on the three-dimensional potential flow theory further verified the rationality of the float structure design under different wave conditions.Secondly,the structural characteristics of the wave power generation system are introduced in combination with the three-dimensional model of the system drawn by Solid Works software.The wave power generation system mainly includes the vibration system,pneumatic system and electrical system,and the working principle of the wave power generation system is analyzed.The vibration system is the main research of this paper.The object is to use the principle of resonance to improve the purpose of wave power generation.The motion actuator of the vibration system uses two parallel-connected series-connected mechanisms.Then,combined with the vibration model established for the vibration system,the vibration analysis was performed to obtain the mathematical model and the steady-state solution of the resonance system.The amplitude-frequency response relationship of the vibration system was obtained by combining the relevant data of the wave power generation system.Determine the damping coefficient of the system and the elastic coefficient of the spring,and perform a finite element analysis of the float using ANSYS Workbench software to obtain its second-order mode and mode shape,verifying the rationality of the structural design;The kinematics analysis of the mechanism was obtained,and the positive and negative solutions of the mechanism were obtained.The speed and acceleration of the mechanism's motion and the motion space of the mechanism were simulated and analyzed using MATLAB software.At the same time,the motion angle changes of each branch chain were also obtained by using ADAMS.Finally,the dynamic analysis of the mechanism of the wave power generation system was carried out.The kinetic energy and potential energy of the moving platform and linear permanent magnet generator were obtained by solving the dynamic equations of the mechanism.The ADAMS dynamic software was used to obtain the motion actuator of the vibration system.The change curve of the bearing force of the middle hinge and the force of each hinge in the actuator change periodically.It has been verified that they are within the reasonable bearing range of the hinge and have certain engineering application value.
