    • Design Validation of High Speed Ratio Epicyclic Gear Technology in Compression Systems 

      Maragioglio, Gaspare; Vannini, Giuseppe; Bradley, Paul; Buckley, Shawn (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Lecture 5: Epicyclic gear technology is a key factor to support thcompression growth strategy in electrified applications, due to the ever increasing transmission ratio required to meet the high compressor speeds. The paper ...
    • Effective Procedure for Turbomachinery Field Balance 

      Pescioni, Alessandro; Maragioglio, Gaspare (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      When unbalance induced vibrations exceed allowable limits, a more accurate system balance is required. If performed at site on assembled machines, it is commonly called field balance. Key point of the activity is the ...
    • Effects of Shaft Geometric Unconformities on the Rotor-Dynamic Behavior in Hard Coupled Equipment 

      Boccadamo, Gianluca; Agnoletti, Paolo; Maragioglio, Gaspare (Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
      Case Study 17: This case study deals with a 25MW turbo-generator train with a semi-rigid connection between generator and gearbox. For this application, machine alignment and connection is a key factor for a smooth ...
    • Gearbox Super-synchronous Lateral Vibration 

      Maragioglio, Gaspare; Pescioni, Alessandro; Libraschi, Mirko (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2015)
    • Torsional Modal Damping of a LCI Driven Geared Moto-Compressor Train: Evaluation, Optimization Criteria and Active Control 

      Calore, Paolo; Maragioglio, Gaspare; Sgro, Daniele; Failla, Lorenzo; Tenca, Pierluigi (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
    • Torsional Modal Damping of a LCI Driven Geared Moto-Compressor Train: Evaluation, Optimization Criteria and Active Control 

      Maragioglio, Gaspare; Daniele, Sgro; Calore, Paolo; Failla, Lorenzo; Tenca, Pierluigi (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      The torsional modal response of geared compression trains driven by Variable Speed Drive Systems (VSDS) can be heavily affected by electro-mechanical interaction phenomena, both in terms of excitation mechanism and resulting ...
    • Transmission Elements: Couplings and Alignment, Gears 

      Maragioglio, Gaspare; Wolford, Chris (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      Suggested Topics: • Coupling guard design • Shaft alignment and tolerances • Balancing methods • Coupling selection and specifications • Shaft alignment methods • Thermal growth considerations • Application of optical ...
    • Turbomachinery and Pump Vibrations 

      Maragioglio, Gaspare; Naldi, Lorenzo; Byrne, James; He, Minhui; Al-Baloshi, Hussain (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This group will discuss plant machinery vibration detection, monitoring, and diagnosis, from a Plant O&M point-of-view. All attendees will be encouraged (but not required) to participate in discussions, and contribute ...
    • Unexpected Vibrations in Gearbox Caused by System Integration Issues 

      Boccadamo, Gianluca; Maragioglio, Gaspare (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This case study deals with a 24MW turbo-compressor unit composed of a gas turbine, a speed reduction gearbox with a lube oil pump mounted on its low speed shaft and two compressors in series. The unit was subject to high ...
