Taking a typical double curvature aircraft panel part as an example, the 2 kinds of shot peening paths were designed according to part characteristics, which were analyzed by Geomagic software. Next, the initial mapping relationship between shot peening parameters and equivalent temperature was established, and the “temperature field” equivalent simulation was carried out by finite element software ABAQUS with the order of the transient steady-state method. And then, Geomagic software was used to characterize the forming error. According to its forming error, the plan of the path was optimized, and the ideal forming result was obtained. Finally, the forming result was verified by a shot peening test of a 1:1 test piece. The result showed that the equivalent simulation method can predict the forming result of the established shot peening path correctly and optimize the shot peening path, which was of great significance to the path designing of shot peening forming.
