基于弹道明胶靶标的防暴服防护效能评估研究

The Study on the Evaluation of Anti-Riot Suit Protection Effectiveness Based on Ballistic Gelatin Targets

摘要: 本研究旨在评估防暴服的防护效能，通过引入弹道明胶靶标作为测试介质，并结合内嵌式传感器技术，实现对防暴服在暴力冲击下的能量吸收、分散及传递机制的精准评估。实验选取内嵌金属板型和无金属板型两组防暴服进行对比分析。采用自由落锤冲击试验机模拟暴力冲击场景，分别进行了背衬胶泥实验和弹道明胶靶标实验。结果表明，在无金属板状态下，防暴服前胸区域的胶泥凹陷深度显著低于后背区域，而加入金属板后，前胸与后背的凹陷深度均显著降低，展示了金属板对防护效能的增强作用。在弹道明胶靶标实验中，内嵌金属板的防暴服显著降低了冲击过程中的压力峰值，进一步验证了金属板在分散和吸收冲击能量中的关键作用。本研究为防暴服防护效能的评估提供了更加科学、客观的数据支持，为防暴服的设计优化提供了有力依据。

Abstract: This study aims to evaluate the protective effectiveness of riot gear by introducing ballistic gelatin targets as the testing medium and combining this with embedded sensor technology. 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.
