摘　　要：针对破片战斗部的杀伤破片击穿和引爆靶弹的毁伤机制 ,介绍一种具有实用价值的分析计算法 ,对破片穿靶的侵彻过程进行了系统的研究 ;推导了正 (斜 )击靶的极限穿靶速度Vcni(Vci) ,并用LS DYNA3D三维有限元程序进行仿真模拟验证 ;同时 ,对极限穿靶速度是否可以引爆靶后装药进行了分析和计算 ,引出了具有一定通用性的引爆速度阈值计算公式 。The paper aims at the principle on fragments of fragmentation warhead detonating target missile. At first, it recommends a analysis method which have practically value, and deduces a series of formula of utmost velocity on penetrating target plate, meanwhile, using LS-DY-NA3D of validating emulated research. Then, how to detonate dynamite behind of target plate was studied in the paper, and a formula of calculating detonated velocity was deduced. At last, correctness and feasibility was validated by experimentation.
