Research On The Imitation Keyboard Resonance Structure Of Ocean Wave Power Generation

In a social environment with rapid economic development and rapid technological changes,simply relying on traditional,non-renewable energy to generate electricity can no longer meet people's needs,and the development and utilization of new energy sources is imminent.As a new energy source,ocean energy is not only renewable but also rich,so the research and development of ocean energy has far-reaching significance for alleviating energy shortage and maintaining the sustainable development of society.This paper comprehensively considers the research status of wave power generation equipment and combines the sea conditions in China to design a keyboard-type resonant structure ocean wave generator.The power generation device mainly improves the wave energy efficiency of the wave generator according to the resonance principle,thereby improving the power generation capacity of the wave power generation device.First of all,this paper introduces the current development of foreign and domestic wave power generation,enumerates the more mature wave power generation devices in various countries,and expounds the principle of wave generators,and then analyzes and summarizes various types of wave power generation devices.The advantages and disadvantages of various types of wave generators are summarized.Based on this,a new type of ocean wave generator with keyboard resonance structure is proposed.This new wave generator can use the resonance structure to improve the conversion of wave energy to electric energy.Secondly,using Solidworks software for 3D solid modeling,the overall structure of the power generation device is designed,and the vibration structure is designed to provide the efficiency of absorbing wave energy.The resonance structure can mitigate the impact of the wave and improve the reliability of the power generation device.On this basis,the linear micro-amplitude theory and the Froude-Krylov hypothesis method are used to calculate the wave force of the common shape of the float,and the MATLAB software is used for calculation and analysis,and the image of the wave force is drawn to select the appropriate one.The shape of the float increases the absorption of wave energy.Then the force analysis of the working float is carried out.The finite element simulation of the float and the seabed base is carried out by ANSYS Workbench software,and the deformation map and the equivalent stress map are drawn to verify the reliability of the working condition of the float and the seabed base.Finally,the vibration system is analyzed and calculated to solve the natural frequency and the main vibration mode of the resonance system.Then,the steady state solution of the vibration system is calculated by the vibration mode superposition method,and the spring stiffness coefficient k and the damping coefficient of the system are calculated.Using MATLAB The software simulates the vibration system and obtains the motion law of the vibration system.
