WebMay 27, 2014 · For output to be in psi, you need to scale the PSD function so that it is in consistent units, instead of G. For instance: If the input is a vibration with a PSD input of 0.30 G^2/Hz from 10 to 2000 Hz, then you need to enter a value of 0.30* (386)^2. Since the input is now in (in/s2)2/Hz, all the output will be in inches, psi and in/s2. WebThe acceleration spectral density (ASD) function is a common way for expressing vibration in spectral terms and typically comes in units of g 2 /Hz. The following steps provide an … Webwhere G RMS is the root mean square acceleration, measured in G’s, f n is the natural frequency, Q is the amplification factor at f n, defined by. where ζ is the critical damping ratio, and [ASD input] is the input acceleration spectral density at f n with units of g 2 /Hz. how do i use quick access
