Flywheel Energy Storage Systems (FESS) convert electricity to kinetic energy, and vice versa; thus, they can be used for energy storage. High technology devices that directly use mechanical energy are currently in development, thus this scientific field is among the hottest, not only for mobile, but also for stationary applications.

A subcritical or supercritical rotor is often employed to improve the energy storage efficiency of flywheel systems. Consequently, it is necessary to introduce Squeeze film dampers (SFD) in the rotor-bearing system to suppress the lateral vibration of the rotor. Although the dynamic behavior of the rotor-bearing system can be investigated
