摘　　要： 采用动态显式有限元法对中厚板轧制过程进行了分析。分析了轧制过程稳定阶段接触区中厚板单元数、轧辊单元尺寸以及中厚板初始速度选择对有限元分析计算结果的影响, 得出了合理的轧制过程有限元模拟参数, 并对某中厚板厂15道次轧制过程轧制力变化规律进行了分析, 稳定阶段轧制力计算结果与实测结果非常接近. 该结果对中厚板轧制过程模拟具有一定的参考意义. The rolling process of medium plate was analyzed with the explicit dynamic finite element method. The effects of number and size of elements in the contact area in the steady stage of a rolling process as well as the initial velocity of the plate on the finite element analysis were analyzed and reasonable simulation parameters in a rolling process with FEM were attained, which was used to analyze the rolling force regularity of medium plat rolling in one steel work. The results were close to the actual measurement and of significance for rolling process simulation.
