Abstract: The new concept and method to deal with the transformation problem of tribo-system conditions were suggested by making use of artificial intelligence and artificial neural network. The computed results were compared to the tested ones and found to agree fairly with the latter. It is feasible to realize rational transformation and application of the tribological data under known tribo-system conditions to the unknown conditions with the assistance of artificial neural network. Thus the artificial intelligence-based method suggested can be effectively and conveniently used to deal with the transformation problem of the tribo-system conditions.
