In this paper, the escalator step chain model is established in SIMPACK a dynamic simulation software to simulate the step chain with different degrees of degradation. And then the data collected in degraded escalator step chain path is analyzed respectively by time domain method and frequency domain method. The analysis results show the reliability of the step chain degradation model based on SIMPACK which provides an important reference for degradation detection of step chain in real life.
