In this paper, vibration modal analysis of a large horizontal axis wind turbine blade of two different materials is carried out by using the finite element analysis software ANSYS. The materials taken are E-glass fiber reinforced plastic and carbon fiber reinforced plastic. For analysis, RRB V-27 is taken as a model having a rotor diameter of 29 meters. Blade length is taken 14 meters with 1-meter hub diameter. The blade is modeled with and without the shear web. Modal analysis conducted as edgewise, flap wise and tensional deflection. Deformation characteristics of the blade for two mentioned materials with and without shear web at different frequencies are analyzed and compared.
