摘要
分析了管类件定径挤压成形工艺，借助于有限元软件Deform-3D平台，对不同参数组合的45^#管类件定径挤压工艺进行了有限元数值模拟。给出了成形极限范围和不同参数对极限变形程度的影响规律。
Extrusion process on the sizing of tube parts is analyzed. The effect of different parameters of tube parts were numerically simulated with plastic deforming finite element method（FEM）, which is based on the platform of general non- linearity finite element method（FEM） software Deform-3D. The extension of forming limit and the effect of different parameters on maximum reduction are obtained.
