有限元法可用于挤压过程的模拟。然而，这种模拟在挤出工业中的应用是有限的，因为所涉及的复杂性。本文提出了一种适用于工业环境的复杂型材挤压成形模拟方法。为此，轴承区域用等效轴承模型建模。通过这种方式，可以在不使用大量元素的情况下描述轴承中的阻力。为了避免为特定模具开发FEM模型所需的耗时和复杂的工作，开发了专门的预处理器。该预处理器提供了CAD系统Pro/Engineer中的模具设计与FEM代码DiekA中的模拟之间的直接链接。该方法被证明为一个特定的模具，并在实践中获得的结果进行比较。(C)2002 Elsevier Science B. V.保留所有权利。
The finite element method can be used for the simulation of the extrusion process. However, the application of this kind of simulations in the extrusion industry is limited because of the complexity involved. In this paper, a method is presented for the simulation of the extrusion of complex profiles, which can be used in an industrial environment. To this end, the bearing area is modelled with an equivalent bearing model. In this way, it is possible to describe the resistance in the bearing without using a large number of elements. To avoid the time-consuming and complex work necessary for the development of the FEM model for a particular die, a specialised pre-processor is developed. This pre-processor provides a direct link between the die design in the CAD system Pro/Engineer and the simulations in the FEM code DiekA. The method is demonstrated for a particular die and the results are compared to results obtained in practise. (C) 2002 Elsevier Science B.V. All rights reserved.
