metadata.value: Nonstationary modes of direct and reverse passage through resonance of an unbalanced rotor equipped
  with an imperfectly mounted ABB are investigated. Two mathematical models are considered. The first
  one is the passage of the critical region with constant angular acceleration, and the second one is the
  motion of the rotor under the action of a constant external torque. The study of the first model has shown
  that the presence of the ABB has a significant negative effect on the process of direct passage through resonance, and the maximum amplitude of whirling in this case can exceed the maximum in the stationary
  case. At the same time, in case of reverse resonance passage, the influence of the ABB is positive, and the
  maximum amplitude of the whirling motion is much smaller than in the case of the direct passage. The
  investigation of the influence of viscous damping in the ABB has shown that too small damping affects
  negatively on the dynamics of the transient process, prolonging the time of the resonant oscillations of
  the rotor until the moment of their disruption. The study of the processes of acceleration and deceleration
  of the rotor according to the second model confirms the main conclusions obtained from the first model.
