A new method is proposed for monitoring the vibration signals of operating mechanical systems. Time signals are assumed to be nonstationary and modelled with short-time autoregressive algorithms. Time-dependent frequency features related to vibration sources are extracted from AR models These features are monitored according to Mahalanobis distance, which is a measure to judge the similarity between the input signal and the template in a statistical sense. The method proposed is convenient in use. This paper gives a practical example for the monitoring of vibration signals of a hydraulic piston pump and the diagnostics of its slipper looseness fault.
