Hi Abiszett,
First look where your correlation function decreases significantly,
Find that frequency let's say, F_ds, all values greater than F_ds
should be ignored as the measurement over there is not accurate (due to either you sensor or your hammer tip , your impact or other reasons)...
Hi Yakin,
How do I calculate the vibration amplitude, frequency range and expected acceleration?
means the acceleration amplitude? do you want a measurement or calculation driven from model.
if you know the : accelartion you can retrieve the velocity and than the dis-placement
question...
