| Abstract: | Upsetting process of cast ingot which was 200 more tones weighted was simulated in this article under different conditions with the top die controlled by constant velocity and constant force.The results of the simulation were compared with the actual upsetting process,and the reasonability of the simulation of was analyzed.The results shows that the upsetting simulation with constant force is better than with constant velocity. |
