Random vibration units
Random vibration units
(OP)
I normally input my random vibration units into my controller as g2/Hz. Sadly I have been given a specification quoting an ASD of 1.92m2/s3
Does anyone know how I can convert m2/s3 to g2/Hz.
Thanks

I remember doing this ages ago but was not too sure. Thanks for the prompt response I can now run my test today,
Thanks again.

Peak = a
Peak-Peak=2.a
RMS=a/sqrt(2)
If you are using a calibrator, it'll probbaly be set to a dB(RMS) acceleration value. That would be an RMS value divided by a reference RMS value, then logged, etc.
In my days working in this area, I never trusted any piece of vibration measurement equipment that didn't output instantaneous m/s2, which I could then mangle however I chose.
