Résumé
Aeronautical and aerospace engineering's current push towards lightweight structures is producing airfoils with slender designs, which are more prone to experience geometrical nonlinearities due to large deformation. In this paper, Hamilton's principle is used to derive the bending-torsion coupling equations. The model incorporates the blades' edgewise, flapwise, and torsion deformations. The nonlinear vibration is described by a system of partial differential equations. Vibrations of the blade are theoretically analyzed to determine the natural frequencies. Amplitudes of vibration and natural frequencies of various blade modes obtained in the present study are compared with those previously obtained. The model proposed in this paper can be widely used in the future study.
