On the basis of the rubbing dynamics equation of the Jeffcott rotor–stator model with imbalance, the sensitivity of rotor–stator systems with rubbing is studied. The effect on sensitivity of shaft stiffness and damping, stator stiffness and damping, radial clearance, and stator radial stiffness is investigated. The numerical results are presented and discussed.
