摘要
概述了基于有限元技术的板带轧制研究进展,重点介绍了有限元技术在预测轧制过程力能参数和摩擦,以及板带温度、组织、缺陷方面的应用。讨论了模型、网格、本构类型等因素对轧制模拟准确性的影响,介绍了提高计算效率的途径,分析了现在存在的问题,指明了发展方向。
The development of plate and strip rolling based on finite element simulation is reviewed. The applications of the finite element techniques in predicting the rolling force, heat transfer and friction, as well as the strip temperature, microstructure, defects are introduced especially. The influences of the rolling model, grid, constitutive type and other factors on the accuracy of the model are discussed. The means to improve computational efficiency are introduced. The existing problems are analyzed, and the direction of development is pointed out.
