Is there a formula to calculate the g level at a certain frequency & displacement during vibration testing?
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.
