Based on the analysis of the propagation mechanism of acoustic emission stress waves caused by impact excitation on aluminum alloy plates, The geometrical model of steel ball impacted aluminum alloy plate was built by ABAQUS software, and the stress wave propagation process is simulated and analyzed. The stress wave propagation process is simulated and analyzed and an acoustic emission sensing system based on the principle of edge filtering is constructed. The acoustic emission stress waves were collected to establish the acoustic emission region localization model. The localization method of acoustic emission region based on diffusion mapping and support vector machine is proposed and verified experimentally. Multiple acoustic emission localization experiments were performed on an aluminum alloy plate of 300 mm300 mm2 mm, which was divided into 36 test area. The results show that the localization accuracy is 30 mm30 mm and the positioning accuracy was 97.5%, while consuming 0.781 s. The study provides an effective method for acoustic emission localization.
