| Inhoud: |
The paper presents theoretical and applied aspects of a method concerning the detection and classification of engines' mechanical defects which can be evidenced via acoustic and vibrational emissions. The method is based on Loeve-Karhunen (L.K.) expansion of suitable pre-processed signals and provides a set of uncorrelated parameters which possess a high information content. The method has been applied to a collection of eighteen 4-strokes internal combustion engines which included items subjectively classified as good, affected by valve knock, by connecting rod knock, or by crank rumble and the results provide automatically the original subjective classification without introducing any information concerning it. The method also provides the means for the construction of analogical devices or implementation of suitable numerical algorithms in order to perform automatic classification of defects. |
