ABSTRACT
Squeeze film damper (SFD) is damping devices which has been widely used in rotating machines. SFD can effectively suppress rotor vibration and reduce transmitted forces.The dynamic characteristic model of the SFD considering inertia force was established, and the finite element model of the rotor-SFD system was developed, by combining fluid mechanics
and rotor dynamics in this paper. The influence of structural parameters of the SFD on the cavitation, pressure distribution, stiffness and damping coefficient of the SFD was further investigated. The impact of the clearance of SFD on the transient dynamic characteristics of the rotor-SFD system was also studied.
