为了深入研究六辊CVC轧机的带钢凸度控制能力，采用非线性弹塑性有限元法，利用大型非线性有限元软件MSC.Marc建立了六辊CVC轧机轧制过程三维有限元仿真模型。模型将辊系弹性变形与轧件弹塑性变形耦合在一起，进行统一建模与分析。运用该模型分别改变工作辊弯辊力、中间辊弯辊力、中间辊横移量进行有限元模拟，得到了工作辊弯辊、中间辊弯辊、中间辊横移对接触应力和带钢凸度控制的影响规律。所建模型与分析结果可为六辊CVC轧机的板形控制研究提供理论数据与参考依据。
In order to study the crown control of six-high CVC mill, using nonlinear elastic-plastic finite element method, a 3D FE simulation model of six-high CVC rolling process was developed with the nonlinear FE software MSC.MARC. In the model, the elastic deformation of rolls and the elastic-plastic deformation of workpiece were coupled as a whole. Based on the model, the changes of work roll bending force, intermediate roll bending force, intermediate roll transverse shifting were simulated. The influence rules of the contact stress and crown control were obtained. The model and the calculated results can offer theoretic data and reference frame to establish the shape control model for six-high CVC mill.
