摘要

为了抑制铝合金薄板类零件在橡皮囊成形后出现屈曲的缺陷，采用薄板屈曲微分方程对零件成形后的屈曲进行理论分析，并通过橡皮囊成形实验研究自然时效时间和成形压力对屈曲缺陷的影响。理论分析结果表明：零件法兰屈曲波数与其内外径比有关，通过改变法兰宽度进行实验验证，实验结果与理论分析结果相符；而成形实验结果表明，屈曲缺陷高度随板料自然时效时间的增加而增加，随成形压力的增加而减少。因此，理论分析结果有效，并且可通过减少淬火后成形时间和增加成形压力来抑制屈曲缺陷。

Abstract

In order to restrain the buckling defects of the thin aluminum alloy plate parts after the process of rubber bladder forming, the buckling process is theoretically analyzed using thin plate buckling differential equations, and the effects of natural aging time and forming pressure on buckling defects are studied through the rubber bladder forming experiment. The results show that the flange buckling wave number has the relationship with the diameter ratio, and the forming experiment results with different flange widths show that the flange wave number agrees with the theoretical calculated results, the buckling defect height increases with the increase of the natural aging time, and decreases with the increase of the forming pressure. Therefore, the results of the theoretical analysis is valid, and the buckling defects can be restrained by reducing forming time after quenching and increasing forming pressure.

Key words： aluminum alloys; thin plate; rubber bladder forming; flange buckling; aging time; buckling wave number
