Vibration Overall Level - S&V Toolkit

[ElisaABGroup]

Hi Everybody,

my Company has just bought Sound & Vibration Toolkit (we don't have LabView) and I'm trying to calculate the overall RMS vibration level of frequency spectrum (range 5-100 Hz).

I can't really find how to calculate it, someone could help me?

Thank you very much for your help

Best regards

Hello Elisa,

first of all for using S&V toolkit without LV, you should use SignalExpress, as specified in the following document:

Have you installed SignalExpress?

Hello!

Yes I did. I carried out some measurement and everything works.

The only thing I can not find is how to calculate the overall rms vibration level in a specified frequency range (for example 5-100 Hz)

Thank you very much for your help!

Have a nice day

very sorry not to have responded sooner. Did you already resolve your question? If not, hopefully, the following tips can help.

overall rms vibration level: are you combining data from multiple axes? if so rms = sqrt (x^2 + y^2 + z^2)

you can calculate the power spectrum and then perform a power in band measurement to limit the analysis to a specific frequency range.
