The Analysis Of Huge Horizontal Wind Turbine's Aerodynamics And Strength

The renewable energy has greatly developed in recent years due to the crisis of fossil energy and enviroment. As a type of enviromently-friendly and inexhaustible energy, wind energy went its gloden time of devement in 90s, 20th century. China, as a large consumer of energy, wind power has got quick development in recent years with the state's support. But there is still a big gap between China and west countries in wind power technology, especially in the design of wind turbine's aerodynamics and structure strength.Aerodynamics analysis plays a very important role in the design of the huge horizontal wind turbine, which tells designer how to make a good aerodynamic design. In order to design a good wind turbine, researchers need to make a good analysis on the factors, which have a very important effort on aerodynamics. Strength analysis supplys a guarantee for wind turbine's excellent stability performance, and the quick development of the modern technology needs an excellent method to analyze the strength.Based on the famous software GH bladed, this paper makes a systemic analysis on some of factors which have an very important effort on aerodynamics, such as wind speed, cone angle, blade cord, and so on. What's more, this paper also makes an analysis on wind turbine tower's strength with a modern advanced method.Through the analysis on aerodynamics, we could get the law of some important factors'effort on wind turbine's aerodynamics and the characteristics of the wind turbine's structure, which supply a good guidance on the design of aerodynamics and structure.
