Dynamic Characteristics of Rotor-SFD System with Inertial Effect of SFD

737--749

Squeeze film dampers (SFDs) are damping devices that have been widely used in rotating machines. SFDs can effectively suppress rotor vibration and reduce transmitted forces. This study established a dynamic characteristic model of the SFD considering inertia force and developed the finite element model of the rotor-SFD system by combining fluid mechanics and rotor dynamics. Furthermore, the influence of SFD structural parameters on cavitation, pressure distribution, stiffness, and damping coefficient of the SFD was investigated. The impact of the SFD clearance on the transient dynamic characteristics of the rotor-SFD system was also analyzed.
