摘要

摘要: 采用AUTODYN-2D数值模拟软件，应用冲击起爆Lee-Tarver模型，对钢破片撞击带铝壳Octol炸药的起爆问题进行了数值模拟，分析了冲击起爆机理及破片形状、着速、铝壳厚度等因素对炸药起爆特性的影响规律，利用升-降法得到了破片对Octol炸药的临界冲击起爆速度。研究结果对反导战斗部破片杀伤元素的设计具有指导意义。

Abstract: Numerical simulation for the initiation or ignition of explosive with aluminum shell was carried out following the Lee-Tarver initiation model of the Autodyn-2D code when it was impacted respectively by sphere or column form fragment. The influence on charge detonation of the shape and velocity of fragments, and the thickness of aluminum was analyzed. By means of the up-down method, the critical detonation velocity of Octol was obtained.
