Machinery Vibration Analysis


This course provides more in-depth discussions of single-channel time waveform, FFT, and phase analysis techniques for the evaluation of industrial machinery. It includes acceptance testing, machine severity assessment, use of demodulation and HFE techniques, basic rotor dynamics, basic ODS, and single-plane balancing. This course is partial preparation for the Vibration Analyst Category III Certification Exam. The workshops and demonstrations, scheduled throughout the training course, are used to illustrate theory and applications.

All registered attendees in the Machinery Vibration Analysis training course receive the following:
·         Course Power Points
·         Two-volume test, Machinery Vibration Analysis: Diagnostics, Condition    
          Evaluation and Correction

·         Workshops containing examples, workshop problems and the Body of
          found in ISO 18436-2 Annex A
·         Training course examination study guide
·         Certificate of completion (3.8 CEUs)
The MVA training course will begin at noon and conclude at 6:00 p.m. on Monday; then will begin at 8:00 am and conclude at 5:00 pm Tuesday through Friday. Subject to change.

It is recommended that attendees review the Body of Knowledge found in ISO 18436-2 Annex A prior to the training course.
