基于破片穿深的人员不同损伤严重度发生概率评估方法

Assessment Method for Probability of Occurance of Different Injury Severities in Personnel Based on Fragment Penetration Depth

破片是爆炸性武器的主要杀伤因素,破片致人员损伤严重度的评估是爆炸性武器杀伤威力评估的主要内容。着眼于战场人员的作业能力需求,筛选与损伤严重度判定有关的重要组织器官;基于损伤定级标准与美军战伤评分为基础的损伤严重度评估,建立了不同组织器官不同穿深时的损伤严重度判据;提出了破片在软组织中穿深的计算模型,建立了破片在不同穿透深度时所致不同程度损伤严重度的发生概率。结果表明,基于破片穿深可有效预测人员不同损伤严重度发生概率,为破片人员目标杀伤威力评估提供数学模型。

Fragments are the primary killing factor of explosive weapons,and the assessment of the severity of fragment-induced personnel damage is the main part of the killing power assessment of explosive weapons.This study focuses on the operational capability requirements of battlefield personnel,screens the important tissues and organs related to injury severity determination;establishes the injury severity criteria for different tissues and organs at different penetration depths based on AIS and MCIS-based injury severity assessment;proposes a calculation model for the penetration depth of fragments in soft tissues,and calculates the probability of occurrence of different injury seventies induced by fragments at different penetration depths.The results show that the probability of occurrence of different injury severities can be effectively predicted based on the fragment penetration depth,which provides technical support for the assessment of the target killing power of fragments.
