Abstract

For the end effect produced in the decomposition process of empirical mode decomposition (EMD), based on the analysis on the subsistent method of the wave matching, a new improved method of empirical mode decomposition is founded using a new cut off condition during the process of the decomposition. Through the analysis on the signal produced by the experiment with the crack fault simulation, the results indicate that the method keeps the change trend of the signal at the endpoint preferably, and the characteristic components of the gear have been decomposed effectively.
