| 摘 要： | 在总结以往板带冷轧有限元分析的基础上,综合考虑了轧辊和轧件的接触与耦合变形问题,采用改进的离散化方法,建立了四辊三维弹塑性板带冷轧计算模型.利用所建立的模型对带钢轧制过程轧件的残余应力、变形以及张力对板凸度和压下量的影响进行了模拟分析,模拟结果与实验结果的比较证明所建立的模型是正确的.研究方法与结果为有限元技术在板带冷轧研究方面的应用提供了一条有效途径.

| Abstract: | Based on the FEM analysis for cold rolling of plate and strip carried by former researchers,the four-high three-dimensional elastic-plastic FEM models were established.The contact and coupling deformation problems of rolls and rolled piece were considered as a whole and an improved discretization method was used in the modeling process.The residual stress and deformation of the piece as well as the influences of tension on the crown and screw-down were analyzed by using the models.The comparison of simulati... |
