| 摘 要： | 时效成形是一种用于制造飞机整体壁板零件的成形工艺。由于其具有回弹量大的特点，需要开发一种准确预测成形后回弹量的方法，并在此基础上对模具型面进行补偿，以消除回弹对成形精度的影响。本文将有限元法应用于网格式高筋壁板时效成形及回弹的分析，并通过实验验证了有限元预测回弹量的准确性。提出了一种基于有限元回弹预测的适用于铝合金时效成形的模具型面补偿算法，并应用该算法进行了复杂高筋整体壁板局部件时效成形的修模计算分析。通过9次迭代计算，零件成形误差减小到0.4 mm以内,证明了该算法具有收敛速度快、精度高的优点。 |

| Abstract: | Age forming technique has been developed to manufacture integral wing-skin panel components.A method of accurately predicting springback and modifying tool surface to eliminate the effect of the springback on forming precision should be developed,since huge amount of springback is a characteristic of this forming technology.This article uses finite element method(FEM) to analyze the age forming process of grid-type high flange integral panels,and test results show that FEM analysis results are reliable.Base... |
