摘　　要：针对六辊UCM冷轧机,利用大型非线性有限元软件MSC.Marc建立仿真模型,并利用该模型系统计算了板形板厚综合设定模型中所需的轧制力、工作辊弯辊力、中间辊弯辊力的横、纵向刚度,分析了中间辊横移对轧制力横、纵向刚度的影响规律。并在轧机刚度分析基础上给出了中间辊横移位置设定模型、弯辊力设定模型和空载辊缝设定模型等,建立了六辊UCM轧机板形板厚综合设定模型和设定策略。采用有限元模型验证了板形板厚综合设定后的板形、板厚均满足目标要求。The three-dimensional dynamic UCM mill model is established by nonlinear elastic-plastic finite element method. The horizontal and vertical stiffness of the rolling force, the work roll bending force, the work roll bending force are calculated systematically by the model. The effects of the intermediate roll shift on the horizontal and vertical rigidity of rolling force are calculated by the model. Based on the mill rigidity analysis the paper presented the setting models of inter- mediate roll shift, roll bending force and roll gap and established the integrated set strategy of shape and gauge for UCM cold mill. The set strategy of strip shape and gauge integrated is verified by the finite element model and the gauge and shape meet the requirements after set.
