| Abstract: | The cold rotary forging forming process of car differential bevel gear was simulated by FEM,and was researched through experiment. The deformation process was simulated with finite element method software-DEFORM,the metal flow and filling regularity and character of mechanics field were obtained. The deformation mechanism of gear precise forming was disclosed. The result is basically consistent between numerical simulation and experiment. |
