repeatability and reproducibility in vibrations

repeatability and reproducibility in vibrations

(OP)
Hallo everybody
I´m working on a project where vibration is measured on a production line (oil punps assembly) and I would like to do a R&R study, does any know how to make a repeatability and reproducibility in vibrations when the signal change in time and frequency? what parameter use: displacement, velocity, aceleration, time, frequency, PSD,etc?. Thank you for any advice.
Cheers

RE: repeatability and reproducibility in vibrations

I'd work in the same domain as your customer's spec - if they specify a max acceleration, from a time history, use that, if they specify a max peak psd, use that.

If this is for an engineering based analysis, I'd be inclined to use velocity psd. Analyse each peak of interest separately.

 

Cheers
