The elastic ring assumes a multifunctional role, crucially providing support and reshaping oil-
film thickness distribution in applications such as squeeze film dampers, demonstrating its …

This research paper presents a comprehensive experimental and statistical approach for the
analysis of vibration amplitudes in a high-speed rotating shaft employing a squeeze film …

This paper summarizes the development of hybrid squeeze film dampers (HSFDs) for active
control of rotor vibrations. Previously, it was shown both theoretically and experimentally that …

This paper describes the experimental application of adaptive control to Hybrid Squeeze
Film Damper (HSFD) supported rotors. The HSFD has been shown to be an adaptive …

This dissertation treats a variety of aspects of the lubrication of mechanical components
encountered in aeronautical engines and transmissions. The study covers dual clearance …

In this study, the nonlinear dynamic analysis of the hybrid squeeze film damper mounted on
a gear-rotor-bearing system is presented. The strong nonlinear oil film force, nonlinear rub …

The hybrid squeeze film damper (HSFD) has proven itself to be an effective controlling
device of vibration in rotating machinery. The critical stage in the development of the HSFD …

This paper summarizes the modeling and control of hybrid squeeze film dampers (HSFDs)
for active control of vibration of rotors exhibiting multiple modes. In a recent paper (El-Shafei …

An combined control methodology for suppressing elastic vibration and impact effects in
clearance pairs are developed by employing active control of structural vibration and …

The squeeze film damper is widely used in turbomachinery due to its ability to reduce
vibration, help transition through the critical speed (resonance) and diminish the force …
