| Abstract |
The movement of the simplest model of a statically unbalanced rotor under the condition
of the action of a constant external torque is considered, taking into account the forces of external and
internal damping. Two modes of stationary motion of the rotor are investigated: synchronous whirling
and asynchronous self-excited oscillations. Using the system of equations that describes the rotor
dynamics in polar coordinates, conditions for the existence and stability of both types of stationary
modes are obtained. |
