| Abstract: | The cold rotary forging technology of flange-type workpiece with a long rod wasresearched and the rigid-plastic finite element analysis model was set up. The forming process ofthis technology was simulated by the finite element method. The distributions of stress, strainand strain rate on a workpiece and their changing process during the deforming process wereobtained. These results provided a theoretical basis for grasping the deforming mechanism ofrotary forging and selecting reasonable technology parameters. |
