Diagnostic Tests & Instrumentation Required For Natural Frequency Problem Detection & Correction (30 page booklet)
Highlights:
This paper provides invaluable information on how to perform a variety of natural frequency tests, including both the instrumentation and accessories required to accurately perform these tests.
Test methods taught include impulse natural frequency tests, coast-down and run-up tests; and how to both acquire and interpret Bode' and polar plots which confirm the presence of natural frequencies (resonances of the machinery being evaluated).
In these cases, introductory information will be provided on how to go about correcting such resonance problems.
