[scilab-Users] vibration test analysis

[Charlie Warner]

SciLAB is a very sophisticated analysis package, but for a preliminary look at time-series data; I like to start with NIST Dataplot (http://www.itl.nist.gov/div898/software/dataplot/), which can handle very large data bases, such as I would expect from your vibration alnalyis- including a very fast FFT that can give you your natural frequencies very quickly.   When I have a large data set to analyze, I like to look at it first in Dataplot, before going on to more in-depth analysis (filtering, etc.) in SciLAB.  Dataplot itself is very sophisticated with a good GUI for visualizing data...

Subject: [scilab-Users] vibration test analysis
















All,

 

Does somebody has ever wrote/coded (under
Scilab but not necessary) a program that analyses the vibration tests results (i.e.
automatically find the natural frequencies) ? 

 

I do it manually but studying the transmissibility’s
and the phase changes but I would like to code it under Scilab and of course
there won’t be any human appreciation/analysis

 

The purpose of this email is not to have
this code but to have advices/information’s on the method / algorithm and
so on !

 

In any way It’s a good challenge for
me

 

 

Thanks for any help

 

Paul
