Abstract: To get the vertical roller mill radial stress nephogram, deformation displacement and safety coefficient, and provide a scientific and solution basis for designing key parts of the roll grinding machine transmission device. Based on the structure, working principle as well as force analysis of vertical roller mill, the finite element analysis of rocker arms is carried out on ANSYS Workbench platform by using the CAE technology. 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, and then meshed. Secondly, the material attribute, contact type, load and constraints of rocker arms and grinding roll components are defined, and the total deformation, equivalent stress and safety factor of rocker arms are obtained by numerical calculation. Results show that, the maximum displacement of the up rocker arm is 1.1 mm, and the maximal displacement of lower rocker arm is 6.61 mm. The rotating radii are the largest both on the top of the up rocker arm and under the bottom of lower rocker arm, and stress are bigger in these two places. The minimum safety factor of the up rocker arm is 1.36, mainly concentrated in the fixed pin hole on a rocker and near the small fillet, and the minimum safety factor of the lower rocker arm is 0.485, mainly concentrated in joint place of the rocker arm and rocker arm shaft.
