In corporations such as petrochemical industry and wind power industry, secure production is guaranteed by machinery condition monitoring. However, since current condition monitoring systems are based on analysis after event, they are not able to predict some emergent incidents or slow-changing breakdowns, or targeted predict equipments faults. Targeted on the issues of instruments’early detection is

Fault feature extraction and representation is the most crucial problem for the reliability and accuracy in the bearing condition monitoring and fault diagnosis. In this paper we select the fractal dimension as the characteristic parameter, because it can reflect signal complexity. We calculate the fractal signal separately from the signal of time domain and frequency
