| 摘 要： | 用几何分析和数值模拟相结合的方法,研究了具有横向浪形的中厚板在矫直过程中的演化。研究结果表明,具有横向浪形的中厚板可以通过辊式矫直得到矫直;在矫直过程中,浪形处弯曲应力层、应变层发生中性层偏移。由于板材中性层的偏移,使板材的不同部分产生延伸和压缩,这种效应明显地改善了板形。浪形矫直效果产生主要在第1矫直单元和第2矫直单元,随着矫直单元增加,平直精度进一步提高。同时增加压下量,矫直后平直精度将有所提高。

| Abstract: | Evolvement of plate wave in level was studied by using both analytic geometry and FEM.The analytic geometry and simulated results show that the relative accurate results can be obtained between analytic geometry and simulated results.It is possible that the roll leveler maybe smooth wave of plate and enhance the flatness of plate.It is occured that the offset of stress and strain layer in the level init.The effect of wave level exists in the first and second level unit,and the flatness of plate is increased in sequel level unit.The results show that the increasing the entance intermesh is the means of increasing flatness of plate. |
