喷丸强化是一种机械表面强化工艺，广泛应用于各个行业，以增加部件的疲劳寿命。该过程严重依赖于后处理定量，例如Almen条带系统。与合适的传感器取代Almen条系统的主要目标，本研究的目的是实现实时监控的过程中，并找到一种替代方法来量化它通过相关的传感器信号Almen强度。评估了使用压力传感器的典型喷丸喷嘴上的压降及其与使用高速摄像机和ShotMeter™在不同操作条件下获得的喷丸速度的相关性。分析来自压力传感器和喷射速度的信息，以确定与过程输入（压力和质量流率）和过程输出（Almen强度）的任何相关性的存在。通过在系统的入口和喷嘴处部署压力传感器，该研究展示了在不使用Almen条带系统的情况下对喷丸过程进行实时监测和控制的能力。
Shot peening is a mechanical surface enhancement process that is extensively used in various industries to increase fatigue life of components. This process relies heavily on post-processing quantification such as Almen strip system. With the main objective of replacing the Almen strip system with suitable sensors, this study is performed with the intent of achieving real-time monitoring for the process and finding an alternative means to quantify it by correlating sensor signals to Almen intensity. The pressure drop across a typical shot peening nozzle using pressure sensors and its correlation to shot velocities using a high-speed camera and a ShotMeter™ obtained at different operating conditions was evaluated. The information from the pressure sensors and shot velocity was analyzed to ascertain the presence of any correlation with process inputs (pressure and mass flow rate) and process output (Almen intensity). By deploying pressure sensors at the inlet of the system and the nozzle, the study demonstrates the capability for a real-time monitoring and control of the shot peening process without using Almen strip system.
