“…Therefore, the EAVGH-CSC-EES method proposed in this paper is used to process the signal y(t). In EAVGH-CSC-EES method, the window length Nw is 2 6 , cyclic frequency resolution is 0.1Hz, the maximum cycle frequency αmax is 100Hz, w[n] is selected as the Hanning window, the result of the processing is shown in Fig. 10.…”

“…This brings great difficulties to the fault diagnosis of the equipment. Therefore, how to effectively and accurately identify the fault impact signal of the rolling bearing from the vibration signal with strong background noise has become a key research issue [4][5][6].…”

“…In most cases, they are undesirable and harmful, as they shorten the service life of equipment and even cause serious accidents [1]. Recently, with the rapid development of sophisticated industry, such as high-speed trains [2], precision optical instruments [3] and stealth submarines [4], the requirements on the vibration environment have become increasingly strict. Considering the contradiction between the load-bearing capacity and the low-frequency vibration isolation of traditional linear vibration isolators, nonlinear theory is widely adopted for better isolation performance [5].…”

“…However, the fault impulses in the vibration signal are always overwhelmed by a large amount of background noise and complex interferences. Therefore, an effective fault feature extraction method may be very important for fault diagnosis of rolling bearings [3,4].…”
