Influência da rotação no comportamento dinâmico de rotores flexíveis

Show the dependence of the natural frequencies of a flexible rotor on its speed ofrotation. Emphasis is given to the rotatory inertia and the giroscopic moment. A simplified analysis is first made of a model with two degrees of freedom. Then, a continuous cantileveredsystem is simulated through a differential equation. The disc is considered as a boundary condition. Finally a last continuous model considers the disc in the differential equation, with its inertial and giroscopic effects. Numerical examples show the validity of the method, comparing the discrete and continuous models.
