    • API High Speed Balancing Acceptance Criteria and Pedestal Dynamics 
      Pettinato, Brian; Hantz, Brian; Wang, Qingyu (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Acceptance criteria for high-speed balancing of turbomachinery are specified in API standards based on either pedestal velocity or shaft displacement. In addition to performing balancing, the measured displacements can ...
    • 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 ...
    • CST15 - Morton Effect With Pedestal Support Influence 
      Wang, Qingyu; Li, Wei; Hatori, Hiroki; Pettinato, Brian (Turbomachinery Laboratory; Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      This Morton effect case is unique since the mitigation method during the high speed balance (increasing the bearing clearance) is opposite to the mechanical test method (decreasing the bearing clearance). The investigation ...
    • 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 ...
