Time Averaging

Description:
29 Page Booklet on How Time Waveform Analysis & True
Synchronous Time Averaging Can Be Used To Effectively Evaluate
Machines Which Have Problems Not Necessarily Detectable By FFT
Analysis Alone
Part
Number TWA-1 (29 page booklet) - $59
Highlights:
-
This
paper acknowledges that time waveforms can be very complex looking
plots, but can often detect problems which FFT spectral analysis
alone cannot.
-
For
example, spectral analysis alone can almost never detect a cracked
or broken gear tooth, rolling element bearing problems on very
slow-speed machines predominantly operating at or below 10 RPM,
motor start-up transient problems and certain reciprocating
compressor problems.
-
It
also points out how time waveform analysis can be used to add
confirming evidence to problems detected by FFT analysis.
-
Particular
problems might generate very similar looking FFT spectra, but
can generate waveforms which look very different and cause differing
amplitudes of vibration.
-
This
paper will also include information on how an analyst should
properly specify the sampling period (tMAX)
if he desires to detect problems such as bearing and gear problems.
-
This
paper then covers what synchronous time averaging is, what hardware
is required to perform this technique, and shows how synchronous
time averaging can be used to determine where certain problems
are originating (even if nearby machines or rolls are turning
at nearly the same speed).
- Finally,
this paper concludes with a number of invaluable case histories
illustrating how to effectively employ both time waveform analysis
and synchronous time averaging to detect and resolve several real-world
problems.
