| Abstract: | The dynamic operation of the mechanical face seal is decomposed,the motion model of mechanical seal is set up and the vibration performance of the seal ring in the external disturbance is analyzed. Then solve the movement differential equation by the Matlab programming to obtain random time fluid film thickness distribution,film pressure distribution,contact pressure distribution and the leakage between the seal faces during the vibration of the seal,and analyze the stability of sealing ring and influence f... |
