为研究飞机大型座舱骨架的整体成形，在DEFORM一3D软件中对该铝合金锻件的整体锻造过程进行了有限元模拟，并优化了模具结构及坯料。在模拟结果的基础上生产了坯料和模具，并在万吨水压机上对坯料进行了整体锻造，实际生产的锻件质量良好。研究表明，模拟结果与实际生产基本一致，通过大型座舱骨架整体成形的有限元模拟实现了模具结构和坯料的优化，减少了试模次数，提高了锻件的质量。

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 DE-FORM-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.
