[scilab-Users] vibration test analysis

CCo (and everybody as well)

You're right ... 

I had a rapid look on the suggested documents and I think it's not what I'm looking for (essentially because my request was too general and not accurate enough and because I'm a newbie in Signal processing == misunderstanding    :-))) )

In the attached document you'll find typical records from a vibration test on a shaker ... the signal processing has already be done by the equipment & soft.

The purpose is to automatically identify ALL the resonances from the measurement ... both using the response/transmissibility's and the phase analysis ... however in the example you can see that there're many parasites in the phase measurements ....


Cheers

Paul

Paul,

You can encode in scilab your manual procedure. May be you can give a
sample  raw data and your manual calculation then we can suggest some
approaches you may want to try.
