Abstract: The system of the shipborne satellite communication of dual motor drive eliminate gear gap has complicated structure and many vibration factors when it runs in the case of dual motor drive to eliminate gear gap. On the basis of analyzing signal direction and control system structrue of satellite communication antenna dual motor gear gap elimination system, fault tree was listed to clarify the relationship between the factors. The transmission chain fault detection method was raised based on the amperometry of the dual motor drive elimination gear gap system to perform health diagnosis and fault warming. The effectiveness of this method was verified by a fault case, which can provide reference for other similar faults elimination and health diagnosis of servo system.

Key words: vibration, eliminate gear gap, amperometry,fault early warning
