Free Vibration Analysis of Al 2024 Wind Turbine Blade Designed for Uttarakhand Region Based on FEA

摘要

The main objective of this research work is to introduce a new material for wind turbine blades. Al 2024 is selected for the suitability analysis. Finite element Method or Finite Element Analysis is a approximation techniques used for the analysis of complex objects and geometries. Wind power or wind energy is considered as a clean source of energy which produces no environmental harm during operation. The total wind power generation potential of India at a height of 50 m is 50000 MW. In recent years Indian Government has focused on this renewable source of energy. The main part of this research is to identify natural frequencies and natural vibration modes of the Al 2024 wind turbine blade. Wind Turbine blade design is a complex procedure. For the design of wind turbine blade Solid Edge software is used and the model is imported in ANSYS 14.0 for modal analysis. For the suitability analysis of Al 2024 we have done structural and Modal analysis. The results of the analysis are used to verify a structure's fitness for use. The analysis results were verified with experimental result available in literature.
