Description

technical field

[0001] The invention relates to shot peening technology, in particular to a calibration method and execution method of shot peening parts. Background technique

[0002] Shot peening technology is one of the main forming processes of aircraft integral panels at present, such as the wing panels of the American "Constellation" aircraft, the supercritical wing panels of ARJ21 aircraft, and the lower wing panels of A380 aircraft. However, although the process of shot peening equipment is simple, in the face of large-scale aircraft panel forming, the selection of shot peening process and shot peening area has an important impact on the curvature of panel forming. A great deal of waste has also led to an increase in the product development cycle.

[0003] For the formation of aircraft panels under the shot peening process, the finite element method is often used for preliminary pre-research. The methods mainly include temperature field method, stress field method, ...
