Multiple Resonance Vibration Mitigation On A 54,000 HP Parallel Shaft Double Helical Speed Increaser.
(Texas A&M University. Turbomachinery Laboratories, 2000)
Test stand vibration measurements on a partially loaded 54,000 hp, parallel shaft, double helical speed increaser revealed synchronous resonant vibrations near normal operating speed. Further testing confirmed the lateral ...
Wachel's Equation - Origin And Current Evaluation Of API 617 Rotor Stability Screening Criteria
(Texas A&M University. Turbomachinery Laboratories, 2010)
To satisfy API standard 617 (2002) stability requirements, the design of centrifugal compressors must be analyzed against the Level 1 screening criteria for self-excited subsynchronous instability of the rotor lateral ...
Synchronous Motor Lateral Vibration Dynamics - Diagnosis, Resolution, And Field Implementation.
(Texas A&M University. Turbomachinery Laboratories, 1998)
A large, double ended drive synchronous motor experienced
severe, limiting lateral vibration during commissioning of a major
plant expansion. The motor driving a centrifugal compressor
providing process air is decoupled ...
