FRF Graph????

FRF Graph????

FRF Graph????

(OP)
can someone tell me about FRF graph which i've got from harmonic analysis result, especialy, what is the meaning of VALU (y-axis). Is that an Amplitude? Amplitude of what?

As an information, before solution begin, i only add range of frequency, without loading/excitation force. It pure by vibration between 0-35 Hz.



Thank you before...

RE: FRF Graph????

Normally an FRF plot would give you units of output/input, e.g. mm/Nt, or mm/mm.  If you didn't give it any units then maybe it's using some sort of default units.

RE: FRF Graph????

(OP)
and where i must to be insert the units? is that unit show the magnitude of amplitude of vibration? in this case deflection in mode shape?
