Modal Analysis for Blade of Horizontal Axis Wind Turbine
Nitin Tenguria, N.D. Mittal and Siraj Ahmed

Abstract:
The blade of a wind turbine is very important component of the rotor. Now days the use of wind turbine generator has rapidly spread as the clean energy recourse and its size is also getting larger. Because of the difficulty of the maintenance of such large wind turbine blade the model analysis becomes important. In this work, the model analysis is done on a blade of length 38.95 m which is designed for V82-1.65MW horizontal axis wind turbine (supplied by Vestas). The airfoil taken for the blade is NACA 634-221 which is same from root to tip. For doing this model analysis five shapes of spar are used. This analysis is done on finite element analysis software ANSYS 12.0. This approach gives satisfactory results and can be used for vibration analysis of turbo machinery blades and helicopter rotor blades. Natural frequency is lower in the case single web spar.
