This approach allows for a precise assessment of the energy absorption, dispersion, and transfer mechanisms of riot gear under violent impact. The experiment compares two types of riot gear: one with embedded metal plates and one without. A free-falling weight impact testing machine is used to simulate violent impact scenarios, conducting both backing clay tests and ballistic gelatin target tests. The results indicate that, without metal plates, the indentation depth in the chest area of the riot gear is significantly less than in the back area. However, when metal plates are added, the indentation depths in both the chest and back areas are significantly reduced, demonstrating the enhancing effect of metal plates on protective effectiveness. In the ballistic gelatin target tests, riot gear with embedded metal plates significantly reduces the peak pressure during impact, further validating the critical role of metal plates in dispersing and absorbing impact energy. The study provides more scientific and objective data to support the evaluation of the protective effectiveness of riot gear, offering robust evidence for design optimization.展开更多
