This article is about the basic method of random signal modeling and model set criteria, and discusses the optimal order number of bearing vibration signal selection problem. Validated with field measured data, the calculation results show that using Burg algorithm of AR model can well fit the bearing vibration signal time series, and has a certain accuracy, can meet the prediction requirements.
