Advanced Vibration Analysis


This course teaches a wide array of advanced vibration analysis techniques such as two-channel analysis, advanced signal processing, natural frequencies, modal analysis, isolation, and damping. It is partial preparation for the Vibration Analyst Category IV Certification Exam. The workshops and demonstrations, scheduled throughout the training course, are used to illustrate theory and applications.

All registered attendees in the Advanced Vibration Analysis training course receive the following:
·         Class notes on signal processing and dual-channel analysis
·         Workshops containing examples, workshop problems and the Body of
          Knowledge found in ISO 18436-2 Annex A
·         Training course examination study guide
·         Certificate of completion (3.2 CEUs)
The AVA training course will begin at 8:00 a.m. and conclude at 5:00 p.m. every day for four (4) days.

It is recommended that attendees review the Body of Knowledge found in ISO 18436-2 Annex A prior to the training course.
Registration Fee: $2,375 USD
(VI Members are entitled to a 10% discount off registration pricing.)
