摘　　要：运用塑性大挠度弯曲理论,以矩形冷弯空心型钢为实例,计算了冷弯成型弯圆中弯圆半径与轧辊进给量之间的关系,并利用计算机仿真软件模拟了弯圆过程。通过将计算结果与仿真结果进行比较验证了该算法的可行性和准确性。Based on the plastic large bending deflection theory,with the rectangular cold-roll void forming sheet as an example,the paper calculated the relation between arc radius and feed amount of roller,and the sweeping process was simulated by using computer simulation software.By means of contrast between computing result and simulation result,it shows that the algorithm from the theory is feasible and accurate.
