Feature Extraction of Weak Fault for Rolling Bearing based on Improved SSD Denoising
Published 2022-03-01“…Aiming at the problem of early weak fault features of rolling bearings are difficult to be extracted under strong background noise and the components decomposed by the singular spectral decomposition method still contain noise,a method of extracting the weak fault features of rolling bearing based on the combination of singular spectrum decomposition (SSD) and maximum cyclostationarity blind deconvolution (CYCBD) is proposed. …”

FRACTURE CHARACTERS OF SURFACE CRACK IN THE INNER UPSET TRANSITIONAL SECTION OF DRILL PIPE
Published 2017-01-01“…During the drilling operation,the drill pipe near the surface usually stands the largest tension and torsion.Stress concentration is relatively serious in the upset transitional section of the drill pipe,where initiation of fatigue cracks,washouts and even fracture accidents are prone to happening.Based on the actual operating loads of G105 drill pipe,which is near the well head of an ultra-deep vertical well,finite element model of the inner upset transitional section containing a circumferential semielliptical surface crack was established.The fracture characters of the cracked model were simulated under the combination of tension and torsion.For different loading ratios and crack depths,the transition aspect ratios are determined and variation laws of the dimensionless stress intensity factor are fitted along with the crack propagating.This paper provides a basis for study on the fatigue life of drill pipe which is subjected to combined loads.…”
