Abstract

The vibration signal of rolling bearing is complex and nonstationary. In the process of fault diagnosis,if only describe the single fractal characteristics of signal,some certain conditions can’t be identified accurately. Therefore, this paper uses the multi-fractal dimension as the characteristic quantity, puts forward a method based on lifting wavelet transform and multi-fractal dimension for rolling bearing fault diagnosis. The step of the diagnosis goes as follows: firstly, decompose the vibration signal of rolling bearing into three layers and reconstruct it by lifting wavelet transform, to highlight the state characteristics of vibration signal; Secondly, calculate the multi-fractal dimension of reconstructed signal, and take it as characteristic quantity to discriminate the bearing status; finally, the vibration signal of rolling bearing in each condition are selected for experimental comparison and analysis, to prove that the method is feasible.
