Description: The early gearbox fault signal is often very weak, low signal-to-noise ratio, which greatly limits the application of existing diagnostic methods in the early diagnosis, how to obtain the actual vibration signal is to improve the quality of early gearbox fault diagnosis, independent component analysis (ICA) to provide a new way of thinking. In this paper, the application of the ICA in the early diagnosis of gearbox failure, the first analysis of the the mixed vibration signal model of the gearbox, then conducted experiments for specific bearing failure, isolated bearing vibration signal and use the fast ICA algorithm
