A Review of Several Methods for Processing Vibration Data
Current signal-processing technology offers a wide variety of methods for analysis of vibration measurements A few of these have become conventional practice among those dealing with vibration control in vibration sensitive facilities but there are still significant differences between the forms of criteria and measurement methods in common usag |
How to calculate octave spectrum in MATLAB ®?
If x is a matrix, then the function estimates the octave spectrum independently for each column and returns the result in the corresponding column of p. p = poctave (xt) returns the octave spectrum of a signal stored in the MATLAB ® timetable xt.
Can I use engineering vibration toolbox on MATLAB?
For professional use on Matlab, users should contact the Engineering Vibration Toolbox author directly for licensing. The Engineering Vibration Toolbox for Matlab (not the Octave version, or any version that runs on a non-proprietary platform) is free only to owners of Engineering Vibration, Daniel J. Inman.
What is an octave-band Filter?
An octave-band or fractional-octave-band filter is a bandpass filter determined by its center frequency, order, and bandwidth. The magnitude attenuation limits are defined in the ANSI® S1.11-2004 standard for three classes of filters: class 0, class 1 and class 2.
Where did the engineering vibration toolbox for Octave come from?
Support for the Engineering Vibration Toolbox for Octave has come from a number of sources. First and foremost, Daniel J. Inman, who initially tasked me and Donald J. Leo to write version 3.0 of the software for his text Engineering Vibration by Dr. Daniel J. Inman (Prentice Hall, 1994).
1. INTRODUCTION
Current signal-processing technology offers a wide variety of methods for analysis of vibration measurements. A few of these have become conventional practice among those dealing with vibration control in vibration sensitive facilities, but there are still significant differences between the forms of criteria and measurement methods in common usag
3. BANDWIDTH CONSIDERATIONS
Random or broadband vibrations are those that cannot be precisely predicted as a function of time, although they may be transformed into or defined by a spectrum that has no sharp peaks. They are typically produced by such things as vehicle traffic, construction, and turbulence in piping and ducting. Constant frequency or tonal vibrations are tho
9. CONCLUSIONS
A wide variety of processing methods is available to analyze vibration data. The one used for a particular application should be based upon judgment of the particular circumstances of that application. The type of measurement must be adequately documented to show the type of band and averaging, bandwidth and windowing, sample duration, and type o
