Abstract：

The elongation mechanism of large integral wing panel in the process of shot peening forming and shot peen strengthening was analyzed, and several common numerical simulation methods of shot peen forming were also introduced. Rectangle and triangle coverage ratio calculation models were adopted with non overlapping arrangement of peen. The Avrami coverage ratio calculation model was adopted with overlapping arrangement of peen. After the peen impacted the plate, the induced stress distribution on its surface was obtained by the numerical method of multi-shot impacting cuboid cell. Furthermore, the elongation of plate after peen forming and shot peen strengthening was simulated by directional stress method. The validity of the above methods were verified by the experiments of shot peening parameters and curvature of plates, as well as the elongation deformation. Therefore, an ideal result in accordance with the experiment was obtained by applying the numerical simulation method to calculate the elongation of C919 front bottom integral wing panel.
