借助非线性有限元软件Marc,采用弹塑性有限元方法对十八辊轧机辊系进行了模拟,计算模型对辊系的弹性变形与带钢的弹塑性变形按照接触问题进行耦合分析。利用此模型,得出了轧制力对辊系弯曲变形的影响以及辊系弯曲变形沿轧件宽度方向的分布,并分析了轧机工作辊的不同方向弯曲变形情况,由对计算结果的分析可以为该轧机的辊系设计提供理论依据。 With the help of the nonlinear finite element software Marc, the elasto-plastic finite element method was used to simulate the roller system of the eighteen-roller mill. The elastic deformation of the roller system and the elasto-plastic deformation of the strip were calculated according to the coupling problem. By using this model, the influence of rolling force on the bending deformation of the roller system and the distribution of the bending deformation of the roller system along the width direction of the rolling stock are obtained. The bending deformation of the working roller of the rolling mill in different directions is analyzed. From the analysis of the calculation results, Provide the theory basis for the roll system design of the mill.
