Abstract EN
The dynamic vibration absorbers have been applied to attenuate the rotor unbalance and torsional vibrations.
The major purpose of this paper is to research the elimination of the fluid-induced vibration in the rotor/seal system using the absorber.
The simplified rotor model with the absorber is established, and the Muszynska fluid force model is employed for the nonlinear seal force.
The numerical method is used for the solutions of the nonlinear differential equations.
The nonlinear responses of the rotor/seal system without and with the absorber are obtained, and then the rotating speed ranges by which the fluid-induced instability can be eliminated completely and partially are presented, respectively.
The absorber parameters ranges by which the instability vibration can be eliminated completely and partially are obtained.
The results show that the natural frequency vibration due to the fluid-induced instability in the rotor/seal system can be eliminated efficiently using the absorber.
The appropriate natural frequency and damping ratio of the absorber can extend the complete elimination region of the instability vibration and postpone the occurrence of the instability vibration.
