The fractal geometry is introduced into the fault analysis of gear vibration signals, and the correlation dimension is used to characterize the fault characteristics of vibration signals. Through the analysis and calculation of gear fault vibration signals obtained from the experiment, the relationship between the correlation dimension and the gear fault degree is determined, and the influence parameters in the calculation of the correlation dimension are analyzed, and how to select the correlation coefficient Suggestions for embedding dimensions and delay time are suggested.
