The conventional air pressure shot peening process consists of multiple impacts of particles propelled with pressurized air through a nozzle at the surface of mechanical components. An experimental study of the flow of particles exiting the nozzle was conducted. A high speed camera was used for image acquisition of the particle flow. This particle flow was analyzed using a particle tracking (PT) technique and using a digital image correlation (DIC) technique. Those two methods were compared and applied to the characterization of an industrial shot peening flow with several parameters of jet pressure and mass flow rate.

使用粒子跟踪和数字图像相关技术对喷丸粒子流进行实验分析

传统的气压喷丸强化工艺包括通过机械部件表面的喷嘴通过加压空气推动的颗粒的多次冲击。对离开喷嘴的粒子流进行了实验研究。高速相机用于颗粒流的图像采集。使用粒子跟踪 (PT) 技术和使用数字图像相关 (DIC) 技术分析该粒子流。对这两种方法进行了比较，并将其应用于具有多个射流压力和质量流量参数的工业喷丸流的表征。
