RISOn the Experimental Dynamic Force Performance of a Squeeze Film Damper Supplied Through a Check Valve and Sealed With O-Rings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In rotor-bearing systems, squeeze film dampers (SFDs) assist to reduce vibration amplitudes while traversing a critical speed and also offer a means to suppress rotor instabilities. Along with an elastic support element, ...
Dynamic Forced Performance of an O-Rings Sealed Squeeze Film Damper Lubricated With a Low Supply Pressure and a Simple Method to Quantify Air Ingestion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Contemporary squeeze film dampers (SFDs) in air-breathing engines are short in length to limit weight and part count and lubricated with a low feed pressure to reduce oil storage and pumping power. In SFDs, O-rings (ORs) ...
Experiments With a Rotor-Hybrid Gas Bearing System Undergoing Maneuver Loads From Its Base Support
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Gas bearings enable microturbomachinery (MTM) with a large power to weight ratio, low part count, and nearly frictionless motion, thus resulting in systems operating over extended maintenance intervals and with improved ...
