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.
