The system is currently at the betasite at NWA at Minneapolis. Real data at varying experimental conditions were acquired and used for training the neural network. The system is seen to perform well for a range of wheels. However for very small wheels the scanning velocities are significantly faster to distort the signal and hence the system is now designed for a limited range of wheel types. NWA has now acquired an upgraded version of the commercial wheel inspection system with a resident computer that digitizes and stores the signal.
Future plans are to integrate the neural net system with the system software.
The new system will also allow the processing of different wheels scanned at different velocities in a manner that is transparent to the user.
