I would like to generate a random number signal in Simulink with a
given Power Spectral Density. I would like to see how my system
behaves given random vibration profiles from MIL-STD-810F. I created
a transfer function to approximate the PSD profile and used it to
filter the random number signal. It is cumbersom to perform. Any
suggestions would be appreciated.

Search for "phase randomisation" in this newsgroup.
