摘　　要：模锻成形是金属零件的常见成形方法,从设计锻模到试制过程往往需要花费许多时间;本文采用显式动力学有限元软件Ansys/Ls-Dyna对一个模锻加工成形过程进行计算机仿真,分析影响模锻件成形的因素,在设计过程中,通过在计算机上改变参数进行模拟,即可得到比较理想的模具形状和锻件的基本尺寸,对实际的设计制造具有指导作用。Extrusion forging is a very common method of moulding in mechanical engineering.But it often takes much time from the mould designing to trial-manufacture;In this text,there is a simulation of forging moulding machining in which explicit dynamic software Ansys/Ls-Dyna was used,and the elements affected the shape of the workpiece were also analysized.During the designing,the perfect size of the mould can be designed through repeating analysis and simulation on the computer,which can instruct the practical design and machining.
