| Abstract: | In this paper, 2D simulation for the precision forging of airfoil blade has been carried out, with the help of the rigid plastic finite element method. The interface friction along the curved surfaces has been considered in the finite element simulation and the re meshing technique in the local zone of the billet applied. According to the simulation results, we studied the effect of the process parameters, including the deformation temperature, initial strain rate and stroke, on the load, equivalent stress and equivalent strain in the forging process of TC4 titanium alloy. |
