带钢拉伸弯曲矫直机压弯模型的研究

摘要

现有的拉伸弯曲矫直机压弯模型均较为粗糙,并由此导致了设备的结构参数不合理和产品精度低等问题。针对这一现状,在建立拉伸弯曲矫直过程力学模型的基础上利用ANSYS/LS-DYNA软件对该过程进行了有限元模拟,而且利用有限元分析的结果对拉弯矫直机的压弯模型进行了完善。修正后的压弯模型成功应用于生产现场并取得了良好的效果。%The existing bending model of tension leveler is relatively rough,which rsults unreasonable structure pa- rameters of equipments and low accuracy of finished products, etc. Aiming at the above situation, based on mechani- cal model of tension leveling, FEM simulation of tension leveling process is carried out with ANSYS/LS-DYNA. Fi- nally, the bending model of tension leveler is improved through the FEM analysis. The revised bending model is successfully applied to production site and achieved effective effects.
