Abstract:

This paper presents an approach consisting of a wavelet transform based method of multi-level representation of a signal. The basic principle of multiresolution analysis lies in the fact that the signal under analysis is represented as a sum of approximations and details. At each subsequent level, approximations are divided into approximation and details. This method is applied for extracting important features of the vibration signal such as understanding the predominant frequency components. In mechanical systems, each frequency component is associated with specific source of vibration. This technique is applied to a signal similar to a vibration signal emitted by a deep groove ball bearing.
