Annotation: The article is about the results of the factorial analysis of the stressed state of guide pulley joints resting on the sub-pulley structures of the shaft frame-type headgears under operating conditions. The analysis was carried out on the design models consisting of band and solid finite elements implemented within the program complex «Ansys Workbrench 14.0». From the numerous experiments the mechanism of the local stress distribution under support bearings of the guide pulleys was found out, the parameters of the stressed state under changes of the processing and design factors were determined. The obtained results were compared with the full-scale experiment data. In general, the obtained results are the bases for the improvement of the engineering procedures of designing steel structures of the shaft sloping headgears.
Keywords: shaft sloping headgear, sub-pulley structures, guide pulley resting joint, factorial analysis, stressed state, local stresses.
