ISO Vibration Analysis CAT III is a five-days course, the training is intended…
-
Day 1 ( 8 Hours )Filters: Low pass, band pass, high pass, band stopSampling, aliasing, dynamic rangeSignal-to-noise ratioResolution, Fmax, data collection timeAveraging: linear, overlap, peak hold, time synchronousWindowing and leakageOrder trackingCross-channel measurementsCorrelation and coherenceCollecting data – ensuring you have the correct setupWhen should you use time waveform analysis?Diagnosing unbalance, misalignment, bent shaft, eccentricity, cocked bearing, resonance, looseness, and other conditions Phase analysisBubble diagramsDiagnosing unbalance, misalignment, bent shaft, eccentricity, cocked bearing, resonance, looseness, and other conditions
-
Day 2 ( 8 Hours )Natural frequencies and resonancesMass, stiffness, and dampingSDOF and MDOFRun-up coast down testsBode plots and Nyquist (polar) plotsImpact and bump tests Operating Deflection Shape (ODS) analysisCan we prove the existence of a natural frequency?Visualizing vibrationSetting up the jobCollecting phase readings correctlyInterpreting the deflection shapeUsing Motion Amplification

Day 3 ( 8 Hours )How does modal analysis differ from ODS?How does Finite Element Analysis (FEA) differ from modal analysisA quick review of the modal testing process Correcting resonancesThe effect of mass and stiffnessBeware of nodal pointsAdding dampingA ‘trial and error’ approachA ‘scientific’ approachIsolationTuned absorbers and tuned mass dampersWhy do bearings fail?Cocked bearing, sliding on the shaft or inside the housing, loosenessEDM and DC motors and VFDsBearing frequencies and what to do when you don’t have all the detailsThe four stages of bearing degradationUltrasoundHigh-frequency detection techniquesShock Pulse, Spike Energy, Peak Vue, and other techniquesDemodulation/envelopingSelecting the correct filter settingsSpectrum analysisTime waveform analysisLow-speed bearings Journal bearing fault detectionWhat are journal bearings?Measuring displacementIntroduction to orbit plotsUsing your analyzer to acquire orbit plotsIntroduction to centerline diagramsEccentricity ratioGlitch removalHow the orbit changes with pre-load, unbalance, misalignment, instabilities, oil whir and whip
-
Day 4 ( 8 Hours )How do motors work?Diagnosing a range of fault conditions: eccentric rotor, eccentric stator, soft foot, phasing, broken rotor bars, rotor bar, and stator slot pass frequenciesMotor current analysisUnique fault conditionsFlow turbulence, recirculation, cavitationSpectrum analysis versus time waveform analysisWear particle analysisGearmesh, gear assembly phase frequency (and common factors)Tooth load, broken teeth, gear eccentricity and misalignment, backlash and more
-
Day 5 ( 6 Hours )General maintenance repair activitiesReview of the balancing process and ISO balance gradesReview of shaft alignment proceduresDefining the programSetting baselinesSetting alarms: band, envelope/mask, statisticalSetting goals and expectations (avoiding common problems)Report generationReporting success storiesAcceptance testingReview of ISO standards
ISO Vibration Analysis CAT III is a five-days course, the training is intended for people who are confident with spectrum analysis but wish to push on and learn more about signal processing, time waveform and phase analysis, cross-channel testing, machine dynamics, and fault correction.
MDI – Machinery Diagnostics Institute Provides this training as per partnership with Mobius Institute,
Accredit certification of successful completion is issued from Mobius Institute after the training.
Accredit certification according to ISO 18436 is issued from Mobius Institute after passing the ISO examination.
