Abstract :
On the basis of the research on the shock signal, the composition and frequency characteristic of the signal are proposed. Through the field test of the engine gearbox, the acceleration signal is achieved and conducted with spectrum analysis to obtain the natural frequency. A method of transient signal analysis based on the EEMD theory of order domain was presented, through the EEMD algorithm, the signal is decomposed and IMFs are achieved. By the analysis of the IMFs, the characteristic of the shock signal is obtained which can be the foundation for us to clearly research the signal and to analyze typical gear failure.
