Research on Bending Process of Integral Panel Skins
With the advantages such as light weight, high structure intensity and good rigidity, integral panel skins have been widely applied in aerospace industry. The forming process of mechanical milling-filling auxiliary roll bending and the incremental bending of integral panel skins were proposed based on the finite element method and the experiments technique. The research shows that the shapes of panel skins were binded by the ribs plastic deformation. The roll bending was suitable to the panel skins with the low ribs or the simple structure. The incremental forming was suitable to the panel skins with the high ribs or the involutes structure.
