Abstract：

Two kinds of rotary forging finite element models of clamp rotation and hammer revolution for titanium alloy wire were established by the ABAQUS/Explicit simulation software, and the determining on the boundary conditions of contact and movement of two models was introduced. Based on the simulation results, the causes of ellipticity differences of the wire formed by clamp rotation and clamp fixed were analyzed. Then, the radial stress, strain and diameter difference of two models were analyzed by means of numerical simulation, and the calculation time of two models under different mass scaling coefficients was compared. The results show that the calculation time by the hammer revolution model is significantly less than that of clamp rotation model, and the diameter difference and forming structure uniformity by the hammer revolution model is better than that of clamp rotation model. Therefore, the hammer revolution model is suitable for the simulation analysis of rotary forging for titanium alloy wire. In addition, according to the simulation results of two models, the hammer revolution model is verified by the experiment results, which are consistent with the simulation results. Thus, the established numerical simulation method can guide the actual production.
