摘　　要：为解决板带轧制高速高精度在线模型问题,文章基于能量变分原理,研究了一种快速数值算法。该法将变形区划分为有限离散单元,考虑剪切变形作用,建立了高速计算模型,在平面变形条件下实现了对轧制力的仿真。计算结果与实测值、Marc有限元计算结果有很好的吻合。通过对某厂五机架冷连轧的分析,模型可在0.3s内完成全部计算。该算法对深入研究冷热态连轧过程在线控制具有重要实际意义。Based on energy-variational principle, a fast numerical calculational methods is proposed to study the accurate and fast model of on-ling control on plate or strip mill. After the deformation zone is meshed by finite distinct elements, taking the influence of shear strain on rolling force into consideration, fast model of rolling force has been obtained under the plane-strain condition. The rolling forces simulated by the model are in good agreement with that of Marc and experimentation. The calculation of 5-stand continuous rolling using the model can be completed within 0. 3 second. The model is of great important to the application of online control on cold/hot tandem mill of strip.
