Assessment of possibility of using the fractal analysis for machinery diagnostics

Print

The main task of the technical diagnostics is determination of an object state when the data is limited. Analysis of a state is usually done in operation when the data is hard to obtain. Often there is no way to make an unambiguous conclusion, so it may be necessary to use statistical methods.

State determination depends on the completeness of the information, and the more information about the object we have, the lower the risk of an error there is. In this way, searching the object information is a relevant question.

In addition to the statistical methods, a spectral analysis method is widespread in vibration analysis. It allows to give characteristics to a frequency content of a measured signal. Cepstral analysis and wavelet analysis are less common. Using of methods of the fractal analysis is recommended to improve reliability and accuracy of the state determination.
