Spectrum analysis is the primary tool for analyzing vibration problems. Yet, a lot of useful information can be acquired by tracking the vibration characteristics as power is disconnected from the machine.

Overall vibration amplitude levels will indicate if a machine has a problem but determining what that problem could be requires both amplitude and frequency data.  The vibration spectrum provides the most convenient way to analyze those two key vibration parameters. 

Anyone dealing with installed machinery, or even test running motors in the service center, will encounter instances where structural resonance is amplifying machine vibration. The machine may meet stringent specifications in one instance but exceed acceptable vibration levels in another. A good understanding of natural frequencies and the tests necessary to identify them will help solve these vexing situations.

A special discounted collection of 9 webinar recordings focusing on a wide variety of vibration, balancing and alignment topics.

Just $45 for EASA members!

This 12-part recording (15 hours) covers a wide range of topics on vibration.

This webinar series was designed to:

• Provide EASA service center technicians with the technical knowledge they need to effectively measure and diagnose vibration on machines being tested in the service center.
• Provide the foundation understanding necessary to use vibration data as an indicator of machinery condition
• Provide the fundamental knowledge of dynamic balancing necessary to use common balancing instruments in the service center
