RISExperimental Identification of Dynamic Force Coefficients for a 110 MM Compliantly Damped Hybrid Gas Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compliant hybrid gas bearings (HGBs) combine key enabling features from both fixed geometry externally pressurized gas bearings and compliant foil bearings. The compliant hybrid bearing relies on both hydrostatic and ...
Dynamic Performance of Liquid Smooth Annular Seal Operating in the Transition Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the experimental leakage and rotordynamic performance for a liquid smooth annular seal operating in the transition regime. The test conditions include pressure differentials up to 64 bars with 1∼2 bar ...
Dynamic Force Coefficients of Hydrostatic Gas Films for Recessed Flat Plates: Experimental Identification and Numerical Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The following paper focuses on an experimental and analytical study aimed at identifying the dynamic force coefficients of hydrostatic gas films for recessed flat plates. The motivation for the effort was brought upon by ...
Dynamic Characterization of a Novel Externally Pressurized Compliantly Damped Gas-Lubricated Bearing With Hermetically Sealed Squeeze Film Damper Modules
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Ever-increasing demand for cleaner energy is driving the need for higher power density turbomachinery while reducing cost and simplifying design. Gas-lubricated bearings are representing one of the enabling technologies ...
Hermetically Sealed Squeeze Film Damper for Operation in Oil-Free Environments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The following work advances a new concept for a hermetically sealed squeeze film damper (HSFD), which does not require an open-flow lubrication system. The hermetically sealed concept utilizes a submersed plunger within a ...
Compliant Hybrid Gas Bearing Using Modular Hermetically Sealed Squeeze Film Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a new gas bearing concept that targets machine applications in the megawatt (MW) power range. The concept involves combining a compliant hybrid gas bearing (CHGB) with two hermetically sealed squeeze ...
Stability of a Rotor Partially Filled With Fluid: Test Facility and Experimental Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluid trapped in a hollow, rotating component may lead to subsynchronous vibrations, resulting in high vibration amplitudes. This asynchronous response is observed around 0.55–0.92× after passing through the first critical ...
Novel Approach for Optical Characterization of Thrust Collar Lubricated Area: Experimental and Numerical Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thrust collars (TCs) are bearing elements used in geared machinery that transmit axial loads from one shaft to another. TCs are primarily used in integrally geared compressors (IGCs) but are also found in gearboxes and ...
Numerical and Theoretical Investigation of the Gap Flow in Centrifugal Fans for Design and Off-Design Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Industrial turbomachines, such as fans and blowers for drying, venting, cooling or conveying tasks, are often used in industrial applications and frequently are large energy consumers. Thus, there is a need for further ...
Dynamic Response of a Pivot-Mounted Squeeze Film Damper: Measurements and Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Squeeze film dampers (SFDs) are widely used to reduce vibration levels in rotating equipment. These devices are installed in series with bearings and are subjected to precessional motions with the inner and outer damper ...
