以中式模短芯棒拔制过程为例，探讨了相似理论在钢管冷拨计算机仿真中的应用;利用大型非线性有限元程序MARC／Autoforge，在计算机上对其进行了大量模拟，获得了具有实用价值的数学模型．
In this paper, the application of the similarity theory in cold-dialing computer simulation of steel tube is discussed with the example of the drawing process of the short mandrel with the Chinese mold. The large-scale nonlinear finite element program MARC / Autoforge is used to simulate the short- Practical value of the mathematical model.
