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 …

It is significant to detect the fault type and assess the fault level as early as possible for
avoiding catastrophic accidents. In the early fault diagnosis of rolling bearing, the vibration …

: The quality factors determine the resonance of resonance-based sparse signal
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 …

Mechanical equipment is the heart of industry. For this reason, mechanical fault diagnosis
has drawn considerable attention. In terms of the rich information hidden in fault vibration …

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 …

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 …

Multifault detection of rotating machinery at the incipient fault stage presents a challenging
issue due to its interaction feature, complexity, and coupling characteristics. Aiming at the …

In the early fault diagnosis of rolling bearing, the vibration signal is mixed with a lot of noise,
resulting in the difficulties in analysis of early weak fault signal. This article introduces …

Rotating machinery typically consists of multiple rotating components, and its fault signals
contain not only periodic impulse components caused by local defects but also periodic …
