Experimental research of the mode of deformation of sub-pulley structures of shaft frame-type sloping headgear
Abstract: The paper is about the theoretical and experimental survey of the mode of deformation of the guide pulley resting joint of the shaft frame-type sloping headgears. As a result of the mathematical modeling and statistical analysis of the experimental data we have ascertained the mechanism of local stress distribution; the characteristics of the dynamic stresses for testing the sub-pulley structure fatigue stress. We have compared the results of the mathematical modeling and physical experiments and have estimated the resource of the sub-pulley resting joints by fatigue stress. By and large the obtained data provide a basis for the improvement of the engineering procedures of designing steel structures of shaft sloping headgears.
Keywords: shaft sloping headgear, sub-pulley structures, guide pulley resting joint, stressed state, local stresses.
