| Abstract: | The fundamental, the characteristics and the algorithm of the correlation dimension are studied. The characteristics of vibration of the gearbox at fault are analyzed. By the vibration signals analysis of fault gearbox obtained from experiments, the relationship between the correlation dimension and the severity of the fault is revealed. The results show that different working state of the gearbox corresponds to different correlation dimension. Thus, the correlation dimension can be taken as the characteristic parameter to identify the working states of the gearbox. |
