- Abstract
The presence of a fault in a bearing makes the mechanical system evolve from a weakly nonlinear dynamic to a strong non-linear dynamic; therefore the linear methods in time and frequency are not suitable for bearing diagnosis. This article uses a novel nonlinear method for bearing diagnosis, which uses the complexity measure suggested by Lempel and Ziv to characterize the vibration signals. The main advantage of this method over other nonlinear analysis techniques is that it does not require the reconstruction of an attractor; therefore it is suitable for on-line analysis. The results show that the Lempel-Ziv complexity is an effective tool for bearing diagnosis.
