摘要 对比2024铝合金在3种不同状态下的材料性能,确认了2024-W态铝合金的钣金成形优势。采用此状态材料进行实际零件成形,零件成形后底部出现不均匀鼓动。为此通过有限元软件模拟橡皮囊成形过程,研究鼓动成因。通过模拟发现板料大部分均未发生塑性变形,只处于弹性变形阶段,且成形内应力分布不均匀,造成材料压缩屈曲失稳形成鼓动。 This paper compares the mechanical properties of 2024 aluminum alloy in three states,the result confirms that the 2024-W aluminum alloy is one of the best for the sheet metal forming,and produces a part using this aged 2024-W aluminum alloy. After forming,the bottom of the part is not flat. To explain this phenomena,the process of fluid cell forming( Flexforming) is simulated by using the software Pam-stamp. The result shows that the materials' compressive buckling is caused by inhomogeneous deformation with most regions in elastic state and thereby the residual stress distribution is inhomogeneous also.
