Does anyone know where I can find out a bit more on the Power Spectral densities for vibration analysis in Mechanica?

Appears you may be either asking on 1 of 2 levels
EITHER
(1) You want to know about how power spectral densities are processed by Pro/Mechanica. If so then can't really help.
OR
(2) You want to know about 'power  spectral densities' as in the principles/theory of. If you are asking about fundamentals such as this then this would indicate that you may be a novice in vibration analysis. Be aware that vibration analyses (at least in my view anyhow) can be very difficult to get your head round - professional engineer level understanding of Fourier transforms ...etc will be prerequisite to understanding what you are doing. It can all go horribly wrong without a measure of experience and significant depth of understanding.

There are many text books on vibration analyses. From my own POV I found the website   www.vibrationdata.com  very useful if you need to go up the learning curve. Hope this helps.

Are you asking how to do PSD studies on ProM?  As in inputing a PSD curve to excite the UUT?
