Fatigue Life Analysis and Optimisation of Coal Mine Belt Conveyor Reversing Roller
Taking the reversing roller of mining belt conveyor as the research object,fatigue life analysis and structural optimisation are carried out based on the finite element method.On the basis of an overview of the main structure and working principle of the DT Ⅱ(A)type belt conveyor,the finite element model of the redirecting roller was established using ANSYS software,and it was found that the fatigue life distribution has a significant inhomogeneity,and that the fatigue life in the middle position of the cylinder shell is the shortest.Taking the fatigue life of the redirected drum as the optimisation objective,the optimal parameters of the three key structures were determined.The new structure is applied to coal mine engineering practice,and the results are found to achieve the expected results,and its service life is expected to be extended by more than 15％,which can create good safety benefits and economic benefits for the enterprise.
