Abstract
An analytical study is carried out on the stability of the full annular rub solutions of an externally excited, modified Jeffcott rotor with a given rotor/stator clearance and cross-coupling influences. The obtained analytical stability conditions provide an opportunity for a better understanding of the dynamical phenomena of rotor/stator systems with rubs, such as jump phenomena and the transition between periodic and quasi-periodic full rub responses as well as between the full annular rubs and the partial rubs. A systematic study on the influence of the system parameters on these phenomena is carried out. It is found that the simultaneous presence of the coefficient of friction and the cross-coupling stiffness coefficient with a proper value may benefit the dynamics of the rotor/stator system with rubs.
