A New Demodulation Method for Mechanical Fault Feature Extraction based on LOD and IEE

A New Demodulation Method for Mechanical Fault Feature Extraction based on LOD and IEE

The rolling bearing and gear fault features are generally shown as modulation characteristics of their vibration signals. The empirical envelope (EE) method is an accordingly common demodulation method. However, the EE method has the defects of over- and undershoot, which may lead to demodulation er...
