Abstract

Shot peen forming is an effective plastic forming method for integral panels with variable thickness used in aeronautical industry. 7050 aluminum alloy flat plates and 3-stiffeners panel were peen formed. The deformation behavior of those workpieces was investigated. The results reveal that the contribution of factors on plate deformation is in following order: thickness, air pressure and moving velocity of workpiece. Moreover, the regression formula about the quantitative relationship between radius of curvature and each factor has been established. Furthermore, the chordwise peen formed deformation of panel with typical structure is basic consistent with the regression formula which could afford some reference to shot peen forming future single shape panels with different thickness.
