Test Verification of Shot Peening Simulation Based on 5G Communication and High-Speed Camera Technology

Based on Eulerian-Eulerian gas-solid two-phase flow model, instantaneous velocity and velocity distribution of shot during shot peening process were simulated and analyzed by of Fluent-EDEM coupling calculation. Space position of shot was recorded by high-speed camera, and the real-time data of shot peening equipment and the image of high-speed camera were uploaded to cloud platform by 5G communication technology. Shot velocity was obtained by image processing, so as to realize the test verification of shot peening simulation. The results show that the relative error between simulation results and measured values of shot velocity under different process parameters was not more than 12.1%, indicating the simulation prediction accuracy of the model was high. The velocity of shot after ejection increased first and then decreased with increasing distance from the nozzle, and the spatial distribution of shot velocity presented a parabolic trend. The developed shot peening intensity analysis software had prediction accuracy of 95%.
