Establishment and Analysis of Vibration System based on Time Series Models
Vibration signals are the important information foi system failures. Forecasting the trend of vibration signals is an important content of condition monitoring and fault diagnosis. A novel time series analysis is presented to analyze and forecast nonlinear random vibration signals. Mathematical models are established to describe vibration signals. First, the non-stationary vibration signals acquired in the field are transformed to stationary time series. Second, the time series models are constructed from the selected reference signals, and nonlinear least square method is used to estimate the models parameters. Then, the vibration signals are forecasted using the models. The application results show that the models can simulate time series of vibration signals quite well with good accuracy and meet the need of forecasting.
