Finite Element Analysis for Rocker Arms of Vertical Roller Mill on the ANSYS Workbench

Based on illuminating the structure,working principle and force analysis of vertical roller mill, the finite element analysis of rocker arms is carried out on ANSYS Workbench (AWE) platform. First of all, the structure of rocker arms and grinding roll components are simplified,then the three-dimensional entity model and meshing model of vertical roller mill both are established. Secondly, the material attribute,contact type,loads and constraints of rocker arms and grinding roll components are defined,and the total deformation, equivalent stress and safety factor of rocker arms are gained after numerical calculation. Results show that the up rocker could meet basically application requirements for its uniform stress distribution. But the lower rocker cannot meet the strength requirements for its low safety factor,and it is necessary to optimize the structure for improving the safety coefficient of lower rocker.
