So far I have not come across any URL on Zoom FFT. The main different from a conventional FFT is the frequency resolution. I have implemented the B&K Zoom FFT using Fortran almost 10 years ago while at Strathclyde University. The method of Zoom are wide and varied depending on the zoom factor...
I don't think there is any reference on this. I have used the acoustic/mechanical vibration to locate and diagnose a noisy vacuum pump due to the roots rubbing. I use a 4 channel spectrum analyzer with microphone and accelerometer simultaneously to correlate the waterfall daigram in real-time.
The paper by VibEngr is certainly worth reading and no doubt your short course is definitely a worthwhile investment for those who are interested in IC engines and reciprocating machineries. I have a request regarding the strain gauge telemetry system for measuring torque. Would it be possible...
Hi,
I did some studying of IC engines years ago, you may find these 2 books useful:
Kerr Wilson, "Practical Solutions to Torsional Vibration", Chapman & Hall, 3rd Edition. 1963.
E J Nostorides, B.I.C.E.R.A., "An Handbook of Torsional Vibration", Cambridge University Press...
