The formula that relates g, frequency, and displacement for sinusodial vibration is:

g = 0.0511 x f2 x D

Where g is zero-to-peak acceleration

f is the frequency and

D is the double amplitude displacement in inches.

For example, ½ g at 2Hz requires a vibration system stroke of 2.45 inches double amplitude.

This formula applies ONLY to sine.
