- W4360996956 abstract "The large diameter percussive reverse circulation drill is widely used in large buildings, bridges and other projects in the drilling process. The structure fracture and weld cracking of the drill bit often happen because of the long suffering the effect of cyclic loading cycles. It is the primary cause for the low service life of the drill bit. This paper uses ANSYS nCode DesignLife fatigue analysis software to evaluate and predict the fatigue life of the drill bit under normal working and eccentric load conditions. It Obtained the fatigue life of the drill bit and the dangerous point of fatigue failure. The structure of the original drill is optimized, which provides theoretical guidance for the further improvement of the large-diameter impact reverse circulation drill." @default.
