For equipment vibration monitoring, Impact uses the ImpactEnergy™ method to measure the vibration of rolling element bearings using stationary accelerometers. By looking for high frequency vibrations in selected bands, Impact extracts information on rolling element bearings that gives an early indication of bearing pitting or spalling. Impact's software will provide the user with advance warning of a catastrophic problem by predicting failure.
VibeCheck™ Vibration Diagnostic Modules
Real-time assessment of mechanical faults (i.e. bearing, rotordynamic, and structural) using vibration signatures at specified locations on the engine can be implemented using feature-based diagnostic techniques. Domain knowledge associated with particular vibration fault frequencies, fixed frequency ranges, per-rev excitations, and structural resonance is extracted from the vibration spectrums acquired from the test cell. For a particular engine type, these spectrums are used to develop a knowledge base from which fuzzy logic membership functions and rulebases are customized for diagnosing mechanical faults.The figures below illustrate a typical engine fault matrix and a vibration “tracked order” plot in VibeCheck™ captured during gradual acceleration from idle to military power.
