Gearbox faults diagnosis based on EMD

Empirical mode decomposition (EMD), as a new signal processing method, is used widely for non-linear and non-stationary process. The decomposition is adaptive and efficient. The diagnosis of gearbox fault is introduced in the paper. With this method, the original signals are decomposed into a finite number of stationary Intrinsic Mode functions (IMFs), then a number of IMFs including main fault information are selected to extract fault features. The experimental result shows that it is validity and efficient to diagnosing gearbox faults.
