In view of coupled vibration of boosters and labyrinth seals rotor/stator structure, and for overcoming the drawback of the prevailing method which disregards the effects of the nonlinearity of rub-impact and fails to identify the influence of key parameters, a coupled vibration dynamic model of booster rotor/stator was established, and the coupled vibration was calculated. Furthermore, the motion stability was analyzed and the influence of key parameters was revealed. The results showed three vibration modes of the coupled vibration: damped mode, sustained mode and divergent mode. Consequently, primary and secondary instability regions can be detected. The location of the instability region varied linearly with the modal frequencies, and changed inversely with the nodal diameters. Accordingly, the length and the number of the instability region reduced as the rotor/stator damping increased or the rubbing force and the initial excitation decreased. The higher angular acceleration indicated the lower coupled vibration amplitude. The results also showed the drawback of the traditional method based on the coupled resonance margin when predicting the dynamic response of the rotor/stator coupled vibration. Only the primary instability regions can be identified and the results were lower than the numerical results.
