CAT-III-Vibration Certification:

 Course Overview:

The Vibration Analysis Level 3 course is intended for personnel who have at least 2 years vibration analysis experience and a good understanding of vibration theory and terminology. The course provides a comprehensive study of diagnostic measurement techniques, a wide range of analysis techniques, and the steps required to manage a successful condition monitoring program.

 Course Content :

The focus of this course is on practical knowledge and understanding of machine knowledge, faults and how to recognize problems in time to plan for an outage and act before catastrophic failure or collateral damage takes place.

Principles of vibration

  • Very quick review of fundamentals
  • Waveform, spectrum, phase, vectors and orbits
  • Signals: transients, pulses, modulation, beating, sum/difference
  • Force, response, damping, and stiffness • Cepstrum analysis

Data acquisition

  • Planning routes, test locations and programs
  • Signal processing
  • Sampling, resolution, Fmax, averaging, windowing, dynamic range, signal-to-noise ratio
  • A/D conversion: constant and variable sampling rate

Vibration analysis

  • Spectral, time waveform and envelope analysis

Equipment testing and diagnostics

  • Impact testing (bump tests)
  • Phase analysis
  • Transient analysis
  • Operating deflection shape analysis
  • Introduction to modal analysis
  • Cross channel measurements
  • Cross channel measurements

Fault analysis in detail

  • Natural frequencies and resonances
  • Imbalance, eccentricity and bent shaft
  • Misalignment, cocked bearing and softfoot
  • Mechanical looseness
  • Rolling element bearing analysis
  • Analysis of turbo-machinery and sleeve bearings
  • Analysis of AC, DC and variable frequency drives
  • Analysis of gears and belt driven machines
  • Analysis of pumps, compressors and fans
  • Lots of casestudies and exercises for participants

 Corrective action

  • Balancing and shaft alignment
  • Resonance control, isolation and damping

Successful condition monitoring program

  • Alarms, reports, management, finances
  • Acceptance testing and ISO standards

Who Should Attend:

It is expected that the participant is either the leader of the vibration team, or takes a leading role in diagnosing faults and making the final recommendation. This person must fully understand all of the data collector options, special test capabilities, and analysis tools; and must understand the widest range of fault condition.
