| Abstract: | The response calculation of labyrinth gas seals with damping sleeve is done by the time-frequency transition method,which includes of the merits of harmonic balance method,dynamic softness method and tracking motion method.The influences of shock absorption on structure are analyzed when the distributing of friction slices is changed along circle and axial direction,then the results are presented. |
