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