In this paper, the escalator step chain simulation model is established to simulate the operation of the step chain under four chain states, which are normal state, chain pitch elongation state, roller wearing and sprocket wheel wearing state, respectively. Then, the wavelet packet analysis method is used to analyze the lateral vibration acceleration data of the driven shaft in these states. The analysis results show that the time-domain energy of each component of the wavelet packet has different degrees of change after the step chain fault, which has great significance for the study of the fault law of the step chain.
