• The turbofan double-rotor engine with afterburner, as a certain type of aero-engine, often presents itself with vibration fault problems in the process of trialing run in the ground text and installed the work process of state, which will affect test the factory qualified rate and the flight mission seriously. In this paper, we mainly adopt the order analysis method to find out the reasons of the engine's vibration hazard from its vibration signal, and then make pertinence measures to solve vibration fault problems, which are combined with vibration test and analysis system of the ground text in the process of actual application. The results of the paper analyze the problem of engine vibration fault effectively and reduce the incidence of engine vibration fault, So as to increase the qualified rate of the engine in the ground test.
