Fault Diagnosis of Rolling Bearings based on SVD-LMD Joint De-noising and TEO

Fault Diagnosis of Rolling Bearings based on SVD-LMD Joint De-noising and TEO

Aiming at the difficulty extracting the local damage information of rolling bearings under the background of random noise，a new feature extraction method based on singular value decomposition(SVD) and local mean decomposition(LMD) joint de-noising combined with Teager energy operator(TEO) is propose...
