Web14 jul. 2011 · If you are only interested in a specific frequency, then you need to use Miles' Equation: Grms = sqrt ( pi/2 * f * Q * ASD ). ASD is the PSD value at the specific frequency, and Q is typically (but not always) 10, it's based on the damping ratio if you know that. If you need Gpk, multiply by 3. Hope this helps.
