| Abstract: | The dynamic finite element simulation has been done to extrusion process of support shaft by using finite element analysis software DEFORM.The stress distribution of die in different rolling reduction has been obtained.The changing situation of the die stress throughout the extrusion process has been studied,especially the stress distribution of the die interior wall,which provides a basis for combined die optimization design under the uneven loads. |
