Abstract

Abstract

In order to explore the influence of the different shot peening parameters on the shot peening results in the shot peening process of 7075 aluminum alloy, the corresponding shot peening process is simulated via ABAQUS software, and the effects of the different shot peening parameters on the surface residual stress distribution, surface roughness and surface three-dimensional morphology are observed. At the same time, the corresponding shot peening process is studied based on the experimental process, by comparing the simulation and experimental results, it is finally found that although there is a certain gap between the two in specific values, the two show obvious consistency in change trend. Therefore, it can be considered that the analysis results of the two are more reliable. At the same time, it is concluded that under the condition of simply adjusting the projectile size and velocity, it is difficult to give consideration to both the surface residual stress and the surface roughness at the same time, but the improvement of shot peening coverage can better take these two aspects into account at the cost of reducing production efficiency.
