Research And Design Of Air-gathering Trough Wind Pressure Power Generation System

With the rapid development of social economy,mobile phones,notebook computers and various household electrical appliances have greatly enriched and facilitated people's production and life,but at the same time,the problems of energy shortage and environmental pollution have also been aggravated.At present,China's energy supply is mainly at the cost of oil,coal and other non renewable resources,is not conducive to the sustainable development of the ecological system,but also caused serious damage to the surrounding environment,so how to develop and utilize renewable clean energy has become a hot research topic in current.Like geothermal energy and tidal energy,wind energy is also a renewable energy source.It is clean,environmentally friendly,energy efficient,and has a wide range of applications.According to existing research,without bending deformation will affect the piezoelectric ceramics electromagnetic interference in the mechanical force,the potential difference in order to complete the mechanical energy and electrical energy in between the two ends,and the piezoelectric material has the advantages of low cost,simple structure,high efficiency,power advantage of the environmental protection,clean and simple the attention of the scholars at home and abroad.This thesis first summarizes the domestic and foreign research status of piezoelectric power generation technology,the basic theory of piezoelectric power generation technology,the use of natural wind pressure makes the piezoelectric properties of piezoelectric material vibration,deformation and energy output,designed a set of gas tank type wind power generation device;and the connection of piezoelectric tablets.A comparative analysis of the situation;the windshield on force of piezoelectric film,piezoelectric stress obtained under different conditions of normalized formula;using real encoding genetic algorithm based on state space model in the MATLAB simulation platform of the gas gathering groove type wind power generation device to optimize the design,and gives the optimal the number and length of the windshield support plate,and the optimum proportion of the length from the center of the column to the length of the intersection of the support plate and the wind deflector and the total length of the wind shield.From the analysis of the wind pressure generation device in the piezoelectric force calculation formula can be drawn,the wind shield in the three,the piezoelectric film by the wind is the largest.The simulation results also prove the correctness of the above conclusions,and then the optimization of the gas tank type wind pressure power generation device is completed by using the real number coding genetic algorithm based on the state space model to optimize the parameters of the gas tank type wind pressure power generation device design.In addition,the thesis provides a reference for the optimization study of wind pressure stress analysis.The design of the gas tank type wind pressure generating device also provides a new method for the study of piezoelectric power generation energy collection technology.
