| dc.description.abstract | A large aero-derivative gas turbine in electrical generation service was exhibiting high vibration at the LP compressor section (1.5 in/s peak) at low load operation. Thorough testing, using Experimental Modal Analysis (EMA) and Operating Deflection Shape (ODS) indicated that the vibration was due to a structural resonance (4-day testing). This excessive flexibility of the baseplate could have been detected immediately (one day) using Motion Magnification Video (MMV) testing technology. This involves a high speed video camera and related software, to magnify the motion of the engine and baseplate in slow motion. Unfortunately, MMV was not yet developed. | |
