Some Features of Rotor Dynamics inside Floating Sealing Ring
Flow-coupled vibrations of system “rotor-ring” are researched. Absence effect of critical rotor velocity and dynamic absorption of rotor vibration in the system “rotor-ring” is described. These properties are caused by aero(hydro)dynamic forces in the clearance between rotor and ring. Result of lowered vibration for high-speed rotor of turbo-pump containing floating sealing rings is submitted.
