To study the integral forming of a large seat cabin frame for an air plane, finite element simulations for the integral forming of the aluminium alloy forging were carried out in software DEFORM-3D,in which the structure of the forging die and the billet were optimized.According to the simulation results, the forging die and the billet were produced, and then the billet was forged integrally on 10000 tons hydraulic press. The quality of the actual forging is very good. The studies indicate that the simulation results are in accord with the actual production ones nearly. Moreover, the optimization of the structure of the forging die and the billet was realized by finite element simulations for the integral forming of the large seat cabin frame, which reduces the times of the trial and error and improves the quality of the forging.
