| Abstract: | This paper presents a novel 3D finite element model for the radial forging process with consideration of mandrel. As different with the previous works, the proposed model captures more accurately the features of the radial forging process. The proposed model is validated. With the proposed model, a comprehensive analysis of the deformation for the tube is presented. The contributions of the present work are: (1) a full 3D finite element model which captures more features of the radial forging process than the models in literature, (2) a proof that a full 3D finite element model is needed, (3) a proof of the effectiveness of the spring bar in stabilizing the contact between the hammer die and work-piece, and (4) the spindle speed has little effect on forging load. Finally, this model can be well used for the analysis and comprehensive understanding of the radial forging process and optimization of the process in future. |
