VIBRATION CONTROL OF ADVANCED HYBRID SQUEEZE FILM DAMPER ON A FLEXIBLE ROTOR SYSTEM

Abstract

Abstract: An advanced hybrid (combination of hydrostatic and hydrodynamic) squeeze film damper (HSFD) concept is described to improve high nonlinearity of conventional hydrodynamic squeeze film damper (SFD). An approximation solution of fluid film-force of the deep recessed HSFD without axial slots which can suitably be used to larger journal eccentricity ratio is presented. The control ability of the HSFD to reduce rotor vibration is investigated both theoretically and experimentally with a modified Jeffcott rotor supported on the HSFD, and compared with the system supported on the SFD.

Key words: Damper, Dynamics, Rotor, Vibration control
