Fatigue Life Analysis of Auger Stem in Soft Coal Seam

Abstract:

The complex force of the auger stem in soft coal seam is taken as the research object. Then the three-dimensional model of spiral pipe is established in the SOLIDWORKS software, and introduced into the workbench simulation platform of ANSYS software to simulate the stress distribution of the screw drill pipe in actual working conditions. According to the results of the analysis, the conclusion is that the stress concentration is around the pin hole of the female joint and the fatigue life of spiral drill pipe is 280.72 x 10 3 cycles.
