3-D Modeling And Simulation Analysis Of Wind Turbine Blades Based On Solidworks

Today, the consumption of energy is in growing with the development of socialeconomy and the rising of the level of people’s life. Leading to the sharp decrease ofoil,coal and other non-renewable resources and serious environment pollution. Use ofrenewable resources, improve the energy structure, reduce the pollution of theenvironment, has become a global energy industry attention a hot issue. Wind energyis a kind of green, clean renewable energy, and wind energy reserves is very rich andinexhaustible. At present, the countries around the world are to speed up the pace ofwind power generators research, and has introduced the first technical equipment. Inour country, the airfoil type of research has remained at ordinary aerofoil stage thatthe new wing type very little. Due to lack of the new wind turbine airfoil geometricparameters and aerodynamic performance parameters, directly suppresses thedevelopment of the large wind turbine blades aerodynamic design.The blade is the core component of wind power generators, the materials of theblade, the airfoil design and structure of the blade direct influence on the developand efficiency of the wind power equipment performance. The pneumatic generatordesign theory of the blade is based on the aerodynamic theory in the wings. Theclassical design theory include Betz theory, simplify the windmill theory, momentumtheory, Wilson aerodynamic design theory and Glauert theory.Choosing different airfoil and obtaining the blade optimization geometricparameters through using air dynamics calculation method;Different airfoil blades areaccurately modeled with3-D software of SolidWorks. Flow simulation analysis isfinished on the software of SolidWorks Flow Simulation and discussing the results ofthe analysis. In the same conditions, Simulating the blades of different airfoil, and thecomparison of the stress of the situation between the blades of the same geometricalparameters but different airfoils, analyzes their the utilization rate of wind power, andto select the most suitable airfoil make wind power generators to achieve themaximum wind power utilization.
