摘　　要：基于大型卷板机成形板材的过程,应用有限元分析软件ABAQUS和疲劳分析软件FESAFE对工作辊疲劳寿命进行了计算和分析。对比分析了不同工作辊转速对工作辊疲劳寿命的影响,最后得出了工作辊转速-疲劳寿命曲线。研究结果发现,在一定范围内,成形速度越快,工作辊疲劳寿命越低。Based on forming process of the large bending machine,through the finite element analysis software ABAQUS and fatigue analysis software FE-SAFE,the fatigue life of working rolls are computed and analyzed.By contrast to the compact on the fatigue life of working rolls under different rotation rate,the rotation rate of working roll-fatigue life curve is obtained. The result shows that,in a certain range,the faster forming speed,the lower fatigue life of working roll.
