Gearbox Fault Diagnosis Based on Improved Variational Mode Extraction

Gearbox Fault Diagnosis Based on Improved Variational Mode Extraction

Gearboxes are widely used in drive systems of rotating machinery. The health status of gearboxes considerably influences the normal and reliable operation of rotating machinery. When a gearbox experiences tooth failure, a vibration signal with impulse features is excited. However, these impulse feat...
