Finite Element Analysis for Rocker Arms of Vertical Roller Mill on the ANSYS Workbench Kun Cheng College of Manufacturing Science and Engineering,Southwest University of Science and Technology,Mianyang, 621010,China chengkun73@163.com Key words: Vertical Roller Mill, Rocker Arm, Finite Element Analysis, ANSYS Workbench Abstract: 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.
At operation, the reduction gear is drove by motor in order to cause millstone to rotate, and the grinding materials are taken into the center of millstone by equipments of locking wind and feeding.
Under centrifugal force, the materials move into millstone around then into grinding roller[3-4].

Therefore, researchers focus on coating materials which are durable to these hard cutting conditions.
TiAlSiN coating is a promising candidate for the machining of hard-to-cut materials thanks to its high hardness and wear resistance [9, 12].
