| Abstract |
We study specific features of the dynamics of high-speed rotor systems with
floating sealing rings in view of the aerohydrodynamic forces acting in the
clearances. We find properties of the "rotor-floating ring" system such
as the possible absence of the critical rotor speed and the dynamic
vibration damping depending on the conditions of contact between the ring
and the housing; we also take into account the possible boiling of the
layer in the clearance. We find a quasistable operation mode due to dry
friction on the ring. For this operation mode, we obtain analytic laws of
motion of the rotor and the sealing ring by the curve fitting method. |
