DOI: 10.1016/j.ifacol.2017.08.2210

Abstract: Abstract Bias of data location and increase of data variations are two typical disturbances, which in general simultaneously exist in the fault process. Targeting their different characteristics, a nested-loop fisher discriminant analysis (NeLFDA) algorithm and… read more here.

DOI: 10.1177/14759217241309311

Abstract: Envelope analysis is one of the most commonly used methods in rolling bearing fault diagnosis. However, when a signal contains heavy noise, even if an appropriate frequency band is selected, the fault information can still… read more here.

DOI: 10.3390/app13106058

Abstract: For large rotating machinery with low speed and heavy load, the incipient fault characteristics of rolling bearings are particularly weak, making it difficult to identify them effectively by direct signal processing methods. To resolve this… read more here.
