The pressure pulsation induced by the pumped periodic pulsation fluid is the main factor of causing fluid resonance and stimulating pipelines vibrations and noise.

It is investigated that the characteristics of stochastic resonance of the periodic pulse signal added Gaussian white noise through a threshold system.
