Practical Rotor Dynamics & Modeling


This course teaches both practical and theoretical modeling of rotating systems using journal and rolling element bearings. 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 Practical Rotor Dynamics and Modeling training course receive the following:
·         Course Notes
·         Workshops containing examples, workshop problems and the Body of
          Knowledge found in ISO 18436-2 Annex A
·         Rotor Dynamics and Modeling Program (USB Flashdrive)
·         Training course examination study guide
·         Certificate of completion (4.0 CEUs)

·         Attendees should bring their own laptop with the ShaftVibA preloaded to
          their laptop for the best learning experience.

The RDM training course will begin at 8:00 a.m. and conclude at 5:00 p.m. every day for five (5) days. 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.
Registration Fee: $2,375 USD
(VI Members are entitled to a 10% discount off registration pricing.)
