HELLO EVERYONE:
I am trying to find information on "Miles rule". Apparantly it is used in vibration work. Can anyone recommend a good book or article?
Thanks to all

RE: MILES RULE
The RMS acceleration response is:
RMS = sqrt[ (pi/2) fn Q Y ]
where
fn is the natural frequency
Q is the amplification factor
Y is the base input acceleration PSD at the natural frequency fn
The base input PSD should be flat within one octave on either side of fn.
One octave means that the higher frequency is twice the lower frequency.
