The Finite Element Analysis Of The Key Components Of Wind Turbine

This paper first discusses the advantages of the wind power generation and thedevelopment of wind power generation industry in China. The main content of thepaper research the static and dynamic analysis of key components of wind turbinefully using the FEA software ANSYS based on the finite element theory.1.Making use of the FEA software ANSYS, the paper discusses the staticanalysis of tower structure for horizontal axis wind turbine with entry and withoutentry, and check up the results. According to the results, the orient of entry under thecertain environment is confirmed. The Dynamic analysis can get the low frequencyand vibration of tower structure. The results of analysis show that the intrinsicfrequency of tower structure is related to material,geometry dimension, the qualityof blade and engine room and groundsill.2.The bending strength and mode of gear are investigated fully based on FEM.The bending strength is checked. The sorts of the intrinsic vibration of helical gearsummarize and the effect to load is caused by natural frequencies.3.The vibration modal analysis of the wind turbine blade are presented .Theresults of the nature frequency and vibration are obtained, and we can configure thenature vibration characteristic of impeller blade and the tower structure system,keeping away from the impeller frequency when impeller run, controlling thevibration response of the tower system.The paper researches the analysis of static and dynamic of the key componentsof the wind power. At the present, the whole analysis of the wind power is a little.the article only builds a foundation for the further analysis.
