摘要

摘要: 利用数值模拟和实验方法, 研究了以铜叠氮化物微装药为基础的微机电系统(MEMS)起爆传爆序列的材料类型对飞片形貌的影响。结果表明:钛适合作为飞片材料, 而铜、铝、聚酰亚胺不适合作为飞片材料; 飞片形貌与材料的力学性能密切相关, 金属飞片的完整性主要取决于有效塑性失效应变, 而非金属飞片的完整性则主要取决于杨氏模量。

Abstract: Numerical simulation and experimental methods were utilized to study the influence of material type on the morphology of the flyer in the field of MEMS booster train based on micro charge involving copper azides.The research results indicate that titanium is suitable for flyer material, while copper, aluminum and polyimide are not.The flyer morphology is closely related to the mechanical properties of material.The integrity of the metal flyer depends mainly on the effective plastic failure strain, while that of the non-metal flyer depends mainly on the Young's modulus.
