project: acoustic testing of metal/rails

I am a final year engineering student at Salford university england. For my final year project i am attempting to design a device which attaches to a railway tracks and can detect the cracks or any structural fatigue, using acoustics pulses transmitted at the rail and retrieved via a speaker system.i was wondering if you know of any research that has been done in this area using this sort of system. i would GREATLY appreciate if you could suggest any way by which i might go about this with regards to the transmitting/receiving equipment needed and any system i could use to analyse the data this is what i am having the big problem with.
Any information at all would be of great help including any books you could recommend.

Thank you for your time.

Peter Mudge of Plant Integrity gave a paper on this type of inspection at Railway Engineering 2002. Maybe if you cantact him he could send a copy of the paper. e mail is pjmudge@twi.co.uk

Prof Peter Cawley at Imperial College email p.cawley@ic.ac.uk is also a good contact on this.

Any problems contact me directly.


Good Luck

RTE Akustik + Prueftechnik in Germany is specialized on acoustic material testing using Resonant Analysis. We have a powerful product (LC-Vibro) which you can use as a device to implement the acoustic testing. Be aware that acoustic analysis is a comparative method and needs a reference basis. A short product description can be seen on our home page www.rte.de (also in English).
Best regards
