Calculation Algorithm for Squeeze Film Damper
Procedia Engineering, 2015 AbstractThis work discusses a number of issues related to the selection of the squeeze film damper type. Here has been performed the analysis of works dedicated to this issue and it has been shown that today there is a large variety of damper designs. Therefore, the method allowing reasonably select the type of dampers and their parameters is required.

Influence of Eccentricity and Angular Velocity on Force Effects on Rotor of Magnetorheological Damper [PDF]
EPJ Web of Conferences, 2018 This article presents the evaluation of force effects on squeeze film damper rotor. The rotor is placed eccentrically and its motion is translate-circular. The amplitude of rotor motion is smaller than its initial eccentricity.
