Mechanical Analysis of Rocker Arm Shell of Medium and Thick Coal Seam MG900/2400-WD Shearer
In order to further explore the possible op timization path of the rocker arm of shearer,the MG900/2400-WD shearer facing medium and thick coal seam mining was studied from the angle of optimization design of the rocker arm shell.First,the design requirements of the rocker arm shell are defined according to the actual needs,and the preliminary design of the rocker arm shell is carried out from the aspects of material,heat treatment process and casting.Then,based on the cast model,ANSYS finite element analysis tool is used to analyze the mechanical properties of the rocker arm shell.The results show that the rocker arm shell meets the expected requirements in both stress and strain indexes,which proves that the design work has achieved initial success,and the rocker arm shell also has potential application value.
