Characterization of rolling element bearing data using the Gottwald and Melbourne’s 0-1 test and the Hugichi fractal dimension

Abstract

The paper considers the characterization of the data extracted from an experimental model of rotor supported on rolling elements. A description of the method is provided as well as an illustration using a standard dynamic map. The 0-1 test for chaos and the Higuchi dimension are shown to be effective tool in the identification of chaotic behavior of the system bearing with and without faults.
