opis: One method of developing models to diagnose and predict the defect stage is, to correlate the objective technical stage with vibroacoustic signal diagnostic parameter. The evaluation data to be correlated, which is usually complicated, should be analyzed well. Principle components analysis offers an approach for linear transformation of the problem variables so that the redundant information is reduced and the characteristics of the signal are more easily extracted. The product chosen for the investigation presented in this paper is a gear. To conclude, the method presented here avoids the need for performing analytical model which are time consuming and costly. It is possible to estimate the type and stage of defect to any gear vibroacoustic signal from the objective parameters of the specially prepared signal without performing simulation models.
