Abstract：

For obtaining the practical peen forming process parameters of integral wing skin panel and establishing the relationship of the forming parameters and the bending radius,the wavilness degree of the panel-face along the wing chord direction,and the generatrix linearity along the wingspan direction of the peen formed integral wing panel,the influence rule of the main forming parameters,such as the shot speed,the space between peening stripes,the blank thickness,the prestress value on the peen forming of integral wing skin panel with bending and torsion combination deformation were analyzed.The technical methods,such as stripe peening,pre-stress peening,were introduced to prevent the spherical distortion.It indicates that with increasing the space between peening stripes,the generatrix linearity along the wingspan direction of workpiece is improved;but the wavilness degree of the panelface along the wing chord direction is increased also;the curvature of workpiece increases with increasing the shot speed,but the influence is slight under the high shot speed;the prestressed peen forming is an effective method to increase the bending radius along the wing chord direction and to improve the generatrix linearity along the wingspan direction of the peen formed panel.
