    • Balancing three-bearing rotors 
      Wang, Qingyu; Pettinato, Brian C. (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      Multistage cryogenic pump rotors are vertically oriented and supported radially by three bearings. However, while the rotors are oriented vertically and supported in three planes, they are balanced horizontally in two-plane ...
    • Rotordynamic Tests Of A Flexible Rotor On Flexure Pivot Journal Bearings And Stability Correlation With Frequency Dependent Characteristics. 
      Pettinato, Brian C.; De Choudhury, Pranabesh (Texas A&M University. Turbomachinery Laboratories, 2002)
      A series of performance, unbalance response, and stability tests were performed on a flexible rotor incorporating two flexure pivot tilt-pad journal bearings, followed by a theoretical correlations using synchronous and ...
    • Shop Acceptance Testing Of Compressor Rotordynamic Stability And Theoretical Correlation 
      Pettinato, Brian C.; Cloud, C. Hunter; Campos, Rogerio S. (Texas A&M University. Turbomachinery Laboratories, 2010)
      This paper presents the rotordynamic stability testing of a nine-stage centrifugal compressor used for hydrogen recycle service. The machine tested was of a basic design and employed no damper bearings, damper seals, shunts ...
    • Torsional Natural Frequencies: Measurement Vs. Prediction 
      Wang, Qingyu; Feese, Troy D.; Pettinato, Brian C. (Texas A&M University. Turbomachinery Laboratories, 2012)
      Excessive torsional vibration can cause damage or failure to rotating equipment trains thereby resulting in costly shutdowns. A comprehensive torsional vibration analysis is the typical method of designing a torsional ...
