大型铝合金整体壁板压弯成形工艺研究

摘要

Pressing bending process of aluminum alloy integral panel was simulated by finite element modeling based on the ABAQUS software. The stress strain state has been researched. The defection and position in pressing bending process were analyzed. The press bending experiments have been tried on the hydraulic press using by lactoprene wad forming technology.%本文利用ABAQUS有限元分析软件,基于Mises屈服准则和动态显式算法模拟了铝合金整体壁板压弯成形过程,研究了压弯成形过程中铝合金整体壁板的应力应变状态,分析了整体壁板压弯成形中易产生缺陷的部位及原因.为避免缺陷产生,提出了聚氨酯橡胶填块压弯成形工艺方法,并进行了成形实验研究.
