摘要
破片对屏蔽装药的冲击起爆效应是弹药毁伤领域的研究重点之一。该过程涵盖冲击波传播、动能侵彻与爆轰形成与成长等多个相互耦合的物理过程,具有高度非线性和瞬时性特征,研究难度较大。为系统揭示其作用机理,国内外学者通过理论推导、试验研究和数值模拟分析等方法开展了广泛探索。基于现有研究,本文从起爆机理、研究方法、经验判据及影响因素等方面,系统梳理了破片冲击起爆屏蔽装药的研究现状,总结了现阶段取得的主要成果,进而对未来重点研究方向作出展望,以期为相关领域的深入探索与工程应用提供参考。
The impact initiation effect of fragments on shielded explosive charges is one of the key research areas in the field of munitions damage.This process involves multiple coupled physical phenomena,including shock wave propagation,kinetic penetration,and detonation formation and growth,characterized by high nonlinearity and instantaneous behavior,making it highly challenging to study.To systematically elucidate its mechanisms,scholars both domestically and internationally have conducted extensive research through theoretical derivation,experimental studies,and numerical simulation analysis.Based on existing research,this paper systematically reviews the current state of research on fragment impact initiation of shielded explosive charges,summarizing the major achievements made to date.It further proposes future research directions,aiming to provide references for in-depth exploration and engineering applications in related fields.
