Detecting rolling element bearing faults with vibration analysis
Using accelerometers or using a broadband pickup and heterodyning for our ears to hear are interesting thoughts but I think would be a challenge on internal combustible engines (with all the other noises and moving parts) but if one could be installed on the IMS bearing cover it might work… OK, I’m off to the lab to develop. |
Works on machinery that are heavy, grounded and has a constant rpm. Performing vibration's wave spectrum "analysis" in a dynamic environment (fluctuating rpm being one alone) requires heavily formulated algorithm. Not to mention that the system would need to go through a serious adaptation/learning cycle each time it is boot-up. Your Porsche would cost $150,000 (min) more if it had a such smart system attached to it.
Still cheaper to buy a second hand engine imo
