Rigid rotor models are widely used for the rotor-bearing stability analysis. This paper presents parametric studies for a squeeze film damper (SFD) using as parameters pressurization, the retainer spring support, and viscosity under the 2π- and π-film assumptions. The results are then validated by direct numerical simulation of the journal orbit.
