| Abstract: | Squeeze film damper bearing (SFDB) is now widely used in aeroengine and other rotating machineries due to its advantages of obvious isolating effect, simple structure, small space and easy manufacturing. In this paper, different kinds of SFDB and the research results on the dynamic characteristics of these SFDB and on the models of fluid dynamic and squeeze film force were introduced. The research achievements on the dynamic response characteristics and stability of the rotating machinery rotor supported on SFDB were reviewed. Also the progressing on the nonlinear responses analysis of such strong nonlinear rotor-damper support system was introduced. The future development of and research on the SFDB was prospected. |
