Reserch On Kinematics And Dynamics Of Lotus Leaf Micro Shock Sea Wave Generation

Since the 21st century,environmental issues and the energy crisis have become two hot issues of common concern in all countries of the world.In response to the solution to the two major problems,each country turned its research direction to the development of new energy.Because ocean energy is the world's richest renewable energy source and the research and development of marine energy has far-reaching significance for mitigating the energy crisis and maintaining the sustainable development of society.Therefor countries began to develop wave power generation devices.Based on the research status of wave power generation equipment and the status quo of energy in China,this paper designs a lotus leaf type micro-impact wave power generation device.The main feature of this device is that the linear permanent magnet generator and the rotating permanent magnet generator are combined to make the conversion efficiency and power generation of the wave energy be greatly improved.Firstly,it analyzes the global and China's wave energy resources and the research status and development trends of wave power generation technology at home and abroad.This paper classifies and introduces wave power generation devices,lists the working principles and key technologies of various typical wave power generation devices,and summarizes their advantages and disadvantages.On this basis,a lotus-type micro-impact wave power generation device suitable for China's seas is proposed.Secondly,Solid Works software is used to model the wave power generation device.Discuss the generation principle and work flow of wave power generation device and introduce the design of key structures in power generation units and the selection of key components.Next,based on the airy wave theory and Froude-Krylov hypothesis method and establish a dynamic response model under the action of waves.The draught depth,heave response and vertical wave force of the oscillating float under the action of the wave are obtained,and the energy absorption power is solved and analyzed.Then,establish a kinematic model of the wave power generation device and kinematics analysis of parallel generators of power generation devices is carried out.Using MATLAB and ADAMS software to carry out kinematics simulation analysis and discuss the singularity and stability of the parallel mechanism.Finally,based on the hypothetical modal method and the Euler-Bernoulli beam theory,the dynamic analysis of the parallel power generation mechanism is studied.Solving the dynamic equations of the parallel power generation system and using ADAMS software to simulate and analyze the force acting on the hinge joints.Solving and analyzing the dynamic equation of the fan blade part of the permanent magnet generation and the system generalized impulse-momentum equation.Simulation analysis of angle and angular acceleration of motor shaft.Based on the finite element analysis method,complete the modal analysis of the whole machine and key components of the wave power generation unit to obtain various modes and modes.
