Abstract:Abstract: The vibration process of the double-faced gas film seal in counter-rotating shafts was studied in this article; two stiffness and damping of the seal were calculated with finite element method; the vibration process of the seal caused by transient force was analyzed; then the effects of the system mass and pressure on vibration of the system was studied. The results declared: free vibration frequency of the system is mainly decided by the mass of the seal racetrack, and the effect of the primary seal ring mass on free vibration frequency is neglected; the different ratio of the system mass with the same racetrack mass has little influence on the convergent time of the vibrating system; as pressure increase, the force that system can endure become small and the system is apt to unstable. The calculation and analysis above may be helpful for the analysis of the dynamic response of the gas film seal in counter-rotating shafts.
