摘要:

橡皮囊成形是飞机钣金零件成形的主要方法之一,其初始毛坯形状的预示是橡皮囊成形中的一个难点问题。针对橡皮囊成形的工艺特点,提出了一种基于一步逆成形有限元法的飞机橡皮囊成形钣金零件毛坯快速精确预示方法。首先将设计好的飞机钣金零件作为最终构形,然后采用一步逆成形有限元法进行初始毛坯的快速反向模拟,最后将通过该方法获得的毛坯外形应用到实际飞机钣金橡皮囊成形中,实验结果表明该方法可以快速精确地预示出飞机橡皮囊成形钣金零件的初始毛坯形状。

Abstract:

Rubber bladder forming is one of the main forming methods for aircraft sheet metal parts in which the prediction of initial blank shape is difficult. In accordance with the technology characteristics of rubber bladder forming, a fast prediction method is proposed for the initial blank shape of a rubber bladder formed part based on one-step inverse forming finite element method. Firstly, the designed aircraft sheet metal part is treated as the final configuration; then a quick reverse simulation is carried out to obtain the initial blank by the one-step inverse finite element method. Finally, the blank outline from the above method is applied to real rubber bladder forming manufacture. The experimental results demonstrate that this method can predict the precise initial blank shape for a rubber bladder forming part.

Key words: rubber bladder forming, sheet metal part, blank, one-step inverse forming, finite element method
