Journal ArticleDOI
Nonlinear Analysis of Rotor-Bearing Systems Using Component Mode Synthesis
TL;DR: In this article, a method of component mode synthesis is developed to determine the forced response of nonlinear, multishaft, rotor-bearing systems, which allows for simulation of system response due to blade loss, distributed unbalance, base shock, maneuver loads, and specified fixed frame forces.
Journal ArticleDOI
Experimental Stability Studies of the Herringbone-Grooved Gas-Lubricated Journal Bearing
TL;DR: Herringbone grooved gas lubricated journal bearing stability, testing effects of geometries and clearances on onset speed for half frequency whirl was performed in this paper, where the effects of geometry and clearance on the onset speed were evaluated.
Journal ArticleDOI
Design of a Squeeze-Film Damper for a Multi-Mass Flexible Rotor
TL;DR: In this article, a single mass flexible rotor analysis was used to optimize the stiffness and damping of a flexible support for a symmetric five-mass rotor, which attenuates the rotor motions and forces transmitted to the support bearings when the rotor operates through and above its first bending critical speed.
Journal ArticleDOI
Experimental Load Capacity and Power Loss of Herringbone Grooved Gas Lubricated Journal Bearings
TL;DR: Load capacity, attitude angle, and power loss were determined for 1-1/2-in.-diam herringbone journal bearings operating in air to speeds of 60,000 rpm.
Wave Fluid Film Bearing Tests for an Aviation Gearbox
TL;DR: In this paper, an oil-lubricated wave journal-thrust bearing assembly was successfully tested at conditions found in general aviation engine gearboxes and showed very good thermal stability.
