Stability Analysis of a High-Speed Seal Test Rotor With Marginal and Extended Squeeze-Film Dampers: Theoretical and Experimental Results [PDF]

open access: yes, 2007
A case study of a high-speed seal test rotor shows how rotor dynamic analysis can be used to diagnose the source of high vibrations and evaluate a proposed remedy.

Direct integration of transient rotor dynamics [PDF]

open access: yes
An implicit method was developed for integrating the equations of motion for a lumped mass model of a rotor dynamics system. As an aside, a closed form solution to the short bearing theory was also developed for a damper with arbitrary motion.

Analytical modeling of circumferential deformation of a hydrodynamical damping device elastic ring with account for friction force

open access: yesВестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение
Analytical modeling of circumferential deformation of an elastic ring of a squeeze film damper taking into account the friction force has been conducted using equivalent infinitesimal substitution combined with elastic ring modeling based on a straight ...

Stabilization of aerodynamically excited turbomachinery with hydrodynamic journal bearings and supports [PDF]

open access: yes
A method of analyzing the first mode stability and unbalance response of multimass flexible rotors is presented whereby the multimass system is modeled as an equivalent single mass modal model including the effects of rotor flexibility, general ...

A computational investigation of vibration attenuation of a rigid rotor turning at a variable speed by means of short magnetorheological dampers

open access: yesApplied and Computational Mechanics, 2009
Rotors of all rotating machines are always slightly imbalanced. When they rotate, the imbalance induces their lateral vibration and forces that are transmitted via the bearings into the foundations.
