RISEffect of Pad Flexibility on the Performance of Tilting Pad Journal Bearings—Benchmarking a Predictive Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tilting pad journal bearings (TPJBs) supporting highperformance turbomachinery rotors have undergone steady design improvements to satisfy ever stringent operating conditions that include large specific loads, due to smaller ...
Response of a Squeeze Film Damper Elastic Structure System to Multiple and Consecutive Impact Loads
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Squeeze film dampers (SFDs) are common in aircraft gas turbine engines, customized to provide a desired level of damping while also ensuring structural isolation. This paper presents measurements obtained in a test rig ...
Forced Coefficients for a Short Length, Open Ends Squeeze Film Damper With End Grooves: Experiments and Predictions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Squeeze film dampers (SFDs) are effective to ameliorate shaft vibration amplitudes and to suppress instabilities in rotor–bearing systems. Compact aero jet engines implement ultrashort length SFDs (L/D ≤ 0.2) to ...
