decomposition (RSSD), and directly affect the performance of RSSD. In the existing RSSD …

Compound faults diagnosis is a challenge for rotating machinery fault diagnosis. The
vibration signals measured from gearboxes are usually complex, non-stationary, and …

The fault diagnosis of rotating machinery is quite important for the security and reliability of
the overall mechanical equipment. As the main components in rotating machinery, the gear …

The selection of approximate values for the weight coefficients of the objective function in the
existing RSSD with large subjective randomness reduces the advantages of this method for …

Compound faults of gear and bearing in a gearbox tend to couple features both of
distributed and localized defects. The vibration signal shows overlapped modulation …

In the aspect of gearbox fault diagnosis, the periodic pulse signal containing fault
characteristics is often overwhelmed with other strong interference components, which …

Wind turbines usually operate in harsh environments. The gearbox, the key component of
the transmission chain in wind turbines, can easily be affected by multiple factors during the …

The vibration monitoring of gearboxes is an effective means of ensuring the long-term safe
operation of rotating machinery. A gearbox may have more than one fault in actual …

Fault diagnosis of gearbox is very important for the security and reliability of the equipment.
In actual working conditions, multiple faults usually occur in a gearbox. However, the multi …

Gearbox is prone to compound fault because of its harsh working environment. The fault
