Vibration Analysis of Layered Composite Beam According to Wind Turbine Blades of Variable Cross - Section

摘要

In this study, for wind turbine blades of variable cross-section vibration analysis of composite beams has been investigated analytically and numerically. Bernoulli composite beam theory used in the analytical part of the beam and the effect of the shear force from the beam has been neglected. A composite beam was created from layers 8. In the numerical part of the study, using finite element method and ANSYS program were used. As result of calculations, without changing the geometry of the beam, it is observed that the natural frequency can be changed by changing the layer angle of the stratified composite beam.
