【Abstract】 Roll speed is one of the major technical parameters for rolling large-sized shaft using cross wedge rolling method.It concerns the forming quality and productivity of the components.In this paper,by using finite software of ANSYS/LS-DYNA,the cross wedge rolling process for forming large-sized shaft parts is simulated.The influence of the roll speed upon the stress and strain of large-sized shaft in cross wedge rolling is analyzed.The results can provide a theoretical foundation for selecting reasonable rolling speed and accomplishing economic production of large-sized shaft with cross wedge rolling method.更多还原
