摘要

为了研究复合壳体装药的抗破片冲击能力,以一维冲击波理论为基础,对其传播特性进行了分析,应用阻抗匹配技术进行不同材质的复合带壳装药在破片作用下的数值模拟,分析各介质接触面的压力、输入炸药的初始压力、能量,结果表明:阻抗排序为大-中-小对冲击波压力有较好的抑制能力,可有效削弱冲击波压力峰值;各分层壳体存在合理的厚度匹配,变壳体厚度的带壳装药抗冲击波效果强于分层等厚度壳体装药。

Abstract

In order to study the impact initiation resistance of fragments to composite shell charge,the propagation characteristics are analyzed based on the one-dimensional shock wave theory. The impedance matching technology was used to simulate the effect of fragmentation on the composite shell charge of different materials. By analyzing the pressure of each medium contact surface, the initial pressure and energy of the input explosive.The results show that the order of impedance is large, medium and small, which can suppress the shock wave pressure, and the impedance of outer material is large, which can weaken the peak platform of shock wave pressure. The thickness of each layer shell is reasonable matching, which can make the anti-shock effect of charging with variable shell thickness stronger than that of layered shell thickness.

Key words： fragments; composite shell; impedance matching; numerical simulation; thickness matching
