Power Spectral Density

Power Spectral Density

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

RE: Power Spectral Density

Appears you may be either asking on 1 of 2 levels
(1) You want to know about how power spectral densities are processed by Pro/Mechanica. If so then can't really help.
(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.

RE: Power Spectral Density

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