Analysis of the resistance to fatigue of shaft frame-type sloping headgear structures
Abstract: There are the results of the analysis of resistance to fatigue of shaft frame-type sloping headgear with multiple-hoist as in the joints guide pulley resting on the under pulley constructions in the article. The analysis was done by the design model consisting of plane and solid finite elements and which was realized in the program «Ansys Workbrench 14.0». Due to the numerical results in the top and bottom sub-pulley frames semi-hipped system headgear was detected the characteristic areas of variable stresses. Was done the analysis of specific areas under the influence dynamic loads, where were identified the characteristics of dynamic stress cycles. Referring to the characteristics of cycles were tested resistance to fatigue by three methods: SNiPII-23-81* (§ 9.2*), DBN V.2.6-163 (§ 1.11.2) and EN1993-1-9-2009 (§ 8). In whole, the results obtained are the base to improve the engineering procedures of designing steel structures of shaft sloping headgear considering the dynamic loads.
Keywords: the shaft sloping headgear, joint of a guide pulley resting, the local stresses, the fatigue stress, the characteristics of stresses cycle, the resistance to fatigue.
