This paper presents a model for the coupled torsional and lateral vibrations of unbalanced rotors that accounts for the rotor-to-stator rubbing. The system degrees of freedom, obtained using Lagrangian dynamics, are the rotor rigid-body rotation, the rotor torsional deformation and two orthogonal la

A model for the coupled torsional and lateral vibrations of an unbalanced rotor is developed. The equations of motion, obtained using Lagrangian dynamics, showed inertial coupling and nonlinear interaction between the rotor torsional and lateral vibrations. A softening eect of the rotor torsional st

In this analysis, a Je!cott rotor model is used which is a thin disk located on a #exible shaft which is simply supported at the ends. The non-linear dynamic equations of the rotor are obtained. A perturbation technique is used to obtain approximate linear equations for the non-linear equations. The

In this paper a dynamic formulation is presented for the coupled textile-rotor system. Both the partial differential equation for the textile thread and the ordinary differential equation for the rotor whirling vibration are derived by Hamilton's principle. When the textile is wound either on or off
