摘要：

The method of signature extracting of rubbing rotor based on the measured impulse response is proposed. The vibration signal is analyzed by the normalization measured impulse response to extract the impact response of system. At the same time, a new method extracting periodic impulse is proposed based on the measured impulse response, which is defined as period series transform, this method can not only extract the periodic impulse responses, but also calculate the period of the impulse response. In view of the measure facility and simpleness of signal component, the method of measuring the signal of rotor and stator at the same time is put forward. The test shows that these methods are effective.
