RESEARCH ON EXTRACTION TECHNOLOGY OF GEAR SYSTEM FAILURE DIAGNOSIS BASED ON STOCHASTIC RESONANCE

摘要

Vibration signals extracted from rotating parts ofmachineries carries lot many information with in themabout the condition of the operating machine. Furtherprocessing of these raw vibration signatures measured at aconvenient location of the machine unravels the conditionof the component or assembly under study. Stochasticresonance system is a method for nonlinear system couldtransform part of the noise energy to the signal. Stochasticresonance method has an important role and significancein the weak fault signal detection. In this paper, accordingto the characteristics of the gear system failure signal,using the stochastic resonance system detects failure weaksignal of the gear system to achieve fault diagnosispurposes.
