防暴动能弹终点效应测试靶标研究进展

Review on Targets of Anti-Riot Kinetic Energy Projectiles Blunt Ballistic Impact

  • 摘要: 为科学评估防暴动能弹的致伤威力,建立可靠的终点效应测试靶标,基于靶标结构特性,将现有测试靶标划分为生物靶标、物理靶标、仿生靶标和数值靶标4类,并通过系统综述已有相关文献,对比分析了各类靶标的结构特点、应用场景、可测参数、损伤判据及其优缺点.研究发现,当前对生物靶标和仿生靶标的研究进展缓慢;数值靶标仿真程度高,但器官、骨骼等材料特性,特别是动载荷下的材料响应特性未知,导致难以真实反应人体在实际冲击中的损伤效应;物理靶标中的人体躯干模型相较目前已有的假人靶标而言,具有解剖结构相似程度高、骨骼内脏受压情况可测等优点,但仍具有内部损伤不可验证等缺陷,结合实际需求指明了测试靶标的下一步发展方向.

     

    Abstract: In order to evaluate the wounding power of the anti-riot kinetic energy projectile scientifically and establish reliable terminal effect test targets, the existing test targets were divided into biological targets, physical targets, biomimetic targets and numerical targets based on the structural characteristics of the targets. And through a systematic review of the literature on four targets, the structural characteristics, application scenarios, measurable parameters, damage criteria and their advantages and disadvantages of various targets were compared and analyzed. The results show that the research progress of biological targets and biomimetic targets is slow at present; the biofidelity of numerical target is high, but the characteristics of organs, bones and other materials, especially the response characteristics of materials under dynamic load are unknown, which makes it difficult to reflect the damage of the human body in actual impact. Compared with the existing dummy targets, the human torso model in physical target has the advantages of high similarity in anatomical structure and measurable compression of bone and viscera, but still has defects such as unverifiable internal damage. Combined with the actual needs, it indicates the next development direction of the test target.
