摘要：

微装药(叠氮化铜)尺寸、金属飞片厚度是影响引信微爆炸序列作用可靠性的关键因素。通过构建微装药驱动金属飞片型微爆炸序列传爆/隔爆能量传递/抑制模型,形成微装药尺寸、金属飞片厚度等尺寸边界的微爆炸序列设计方法。研究结果表明:当微装药直径大于0.8mm,驱动金属飞片速度(2200m/s)增长趋缓;当微装药高度大于0.5mm,金属飞片形成稳定运动速度,可以可靠起爆下一级装药;当微装药尺寸一定时,金属飞片速度随厚度增加而降低,飞片厚度由25μm增加到50μm,可以实现微爆炸序列可靠传爆。结合微机电系统引信安保机构隔爆滑块厚度仿真分析,验证得到0.2mm的镍基滑块可以稳定实现飞片隔爆,最终形成飞片式引信微爆炸序列传爆/隔爆设计边界。

Abstract:

The size of micro-charge (copper azide) and the thickness of metal flyer are the key factors affecting the reliability of fuze micro-explosive train. A detonation transfer/explosion-proof energy transfer/suppression model of metal flyer micro-explosive train driven by micro-charge is constructed, and a design method for micro-explosive train with size boundaries, such as micro-charge size and metal flyer thickness, is proposed. The research results indicate that the speed of metal flyer(2200m/s) increases slowly when the diameter of micro-charge is greater than 0.8mm. When the height of micro-charge is greater than 0.5mm, the metal flyer moves at a stable speed, which can reliably detonate the next charge. When the size of micro-charge is constant, the speed of metal flyer decreases with the increase of its thickness. The thickness of the flyer increases from 25μm to 50μm, which can realize the reliable detonation of micro-explosive train. Through the simulation analysis of explosion-proof slider thickness of MEMS fuze security mechanism, it is verified that the 0.2mm-thick nickel-based slider can stably realize the explosion interruption, and the detonation transfer/explosion interruption design boundaries of flyer-type fuze micro-explosive train are finally formed.
