Abstract：

An incremental rolling equipment was designed, and the modeling, assemble and simplification were conducted by three-dimensional software. Then, the assembly was analyzed by finite element software ANSYS Workbench, and the stress, strain and deformation nephograms were obtained by the static analysis of incremental rolling equipment in the rolling process. Furthermore, the stiffness of equipment was analyzed combining with its material properties, and the locations which are prone to damage in the equipment due to different forces were analyzed. At the same time, the fatigue analysis was performed during the biting process, and the weak locations produced by fatigue damage easily in the equipment were pointed out. Finally, the weakness of equipment was optimized, a new design scheme was proposed, and the static analysis and fatigue analysis of the new equipment were carried out. The results show that the new design scheme can effectively reduce the maximum equivalent stress and deformation amount, and the strength and anti-deformation ability are improved greatly. Thus, the life and safety factor are also improved significantly.
