摘要
通过分析UCM冷轧机工作原理及性能特点,建立了UCM冷轧机工作机座三维模型及有限元模型。与以往模型相比,该模型充分考虑了由于窜辊、辊形、单侧驱动等因素带来的辊系不对称缺陷,极大提高了计算精度及结果可信度。以1 MN为步进,自3 MN施加轧制力至15 MN,得到13个工况下的压上缸行程,进而计算冷轧机刚度系数。将有限元计算刚度系数与现场实测数据计算的刚度系数做对比,误差为0.963%,误差极小。则有限元计算结果可为轧机的刚度设计提供可靠的科学依据。
Through analysis of operation theory and performance features of UCM cold mill. The finite element analytical model of the UCM cold mill housing was established. Compared with the previous models, asymmetric defect caused by the factors including shifting, roll contour and single side driving etc. , are fully considered in this model. Greatly enhance precision and reliability of the results. The stroke of the pressure cylinder via was obtained by applying roiling force from 3MN to 15MN at the step of 1MN. Through the above resuhs, rigidity factors of FEM calculation could be calculated. To compare the rigidity factors between FEM calculating and on- site test calculation, the error was 0. 963%. So the FEM results can provide reliable scientific basis for the mill rigidity design.
