- How to convert the PSD input function of a dynamic random analysis from displacement spectral density to acceleration spectral density?
- I have PSD input in terms of displacement i.e;(m2/(rad/s)vs HZ)
- How to input this PSD data along a particular direction to see the effect of excitation?
- PSD input is not a single value rather it is a range of values
- For structural vibrations, the units may be
– acceleration e.g. [(mm/s2)2/Hz] or [G2/Hz]
– velocity e.g. [(mm/s)2/Hz]
– displacement e.g. [(mm)2/Hz]
- force e.g. [N2/Hz]
