Vibration Testing

[Sparky2003]

Does anyone know of a good website which gives good theory on Vibration testing using shaker tables etc.
I will be doing some Vibration testing on an Electric Motor to simulate real life conditions, however I need to get the background to the test parameters conditions etc.
What does Vibration Spectra mean??

Vibration Specta is the spectrum, or range, of vibration frequencies.
