摘　　要：通过对7075铝合金大型长筒锻件锻造扩孔环节成型方法的深入研究,利用DEFORM-3D软件对长筒分阶段扩孔进行有限元分析及优化,解决了大型长筒形锻件成型时马杠扩孔长度缩短问题。采用该关键技术能够生产出优质的大型长筒形锻件。In this paper,based on the in-depth research on the forging and reaming process of 7075 aluminum alloy large-barrel forg⁃ings,DEFORM-3D software is used to carry out the finite element analysis and optimization of the multi-stage reaming process of the long barrel forgings,and the problem of shortening the reaming length of the horse-bar is solved.The key technologies formed are capable of producing high quality large cylindrical forgings.
