Essay

With the aim to establish the influence of stiffness parameters of elongated blades on their dynamic behaviour in compound rotation, the problems about vibrations of rigid and elastic, rectilinear and curvilinear twisted rods, attached by one end to a rigid disc connected with a rigid or elastic shaft, are set up. The cases of rigid, hinged and elastic attachment of the rods to the rotating disc are considered. It is shown that the resonant regimes of vibrations of the system with rigid blades established on the elastic rotating shaft are possible only in the cases of two blade rotors. It is established that depending on the elastic properties of the curvilinear rods and parameters of their curvature the resonant regimes can appear.
