摘要	A calculation model on the fluid-solid coupling system of gas film and seal rings subjected to axial vibration was established by taking static seal ring as the oscillator, and the Reynolds equation was approximately solved by using PH linearized method, complex function variables separation method and small parameter iterative method. The approximate analytic expression of gaseous film dynamic pressure and gaseous film force were obtained. Axial forced vibration equation of single degree of freedom was established by taking gas film force as the exciting force, which was solved by using the Runge-Kutta algorithm, then the vibration phase chart and the time history chart responded by the different spiral angles and grooved depth were obtained, and the effect of spiral angles and grooved depth on vibration displacement was analysed. The results show that vibration parameters were affected by spiral angles and grooved depth, and the vibration caused by spiral angles is the dominant one. The vibration amplitude of seal ring can be controlled by changing spiral angles and grooved depth, and the dynamic stability of gas seal can be kept by selecting their optimal value. The optimal values of the spiral angles and the groove depth in this example are 74°58′48″ and 5 μm respectively, and which are in agreement with the experimental data.
