摘　　要：解释了压力矫直过程的载荷-挠度模型,阐述了用ANSYS有限元软件建立载荷-挠度模型的方法和步骤。使用该模型可进行矫直行程的计算,解决了有限元方法在自动矫直机上的应用问题。实例计算表明,有限元计算结果与实验结果吻合良好,证实了方法的实用性。Load-deflection model of press straightening process is explained. The method and procedures of establishing load-deflection model by using ANSYS software are described. Based on the model, the straightening stroke can be calculated, so it is solved to apply FEM to automatic straightening machine. An example is given, calculation results by FEM are in good agreement with the experimental results. The validity of the method is proved.
