摘　　要：利用刚塑性有限元法分析纵筋板的成形过程，首次得出筋高沿变形区的变形规律，以及轧制时的筋高、轧制力等，其计算结果与实测结果相吻合．The main feature of rolling strip with ribs is that there is local residual deformation on a normal flat,and it is a new forming process which has the deformation characteristic of both strip steel and profile steel. Using the rigidplastic FEM,the forming process is analyzed. The numerical results of the change of rib height in deformation zone,and the parameters such as separating roll force and rib height are obtained,and the results of calculation is in accord with those from experiments.
