Gearbox Fault Diagnosis based on Time-frequency Combination Feature Extraction and Manifold Learning of MS-LTSA

A fault diagnosis method of gearbox based on time frequency union （TFC） feature extraction and manifold learning of improved supervised local tangent space arrangement （MS-LTSA） is presented. Firstly，a feature extraction method combining time domain，frequency domain and HHT time-frequency domain is...
