探索了一种利用金属丝电爆激励惰性气体产生等离子体强光辐射光学弹药的新机理,应用电爆丝绝热加热模型和惰性气体中电爆丝爆炸激励冲击波模型对电爆丝爆炸特性进行了理论分析和数值模拟.研究发现:为了获得强的脉冲辐射,应选用惰性气体作为发光工质,并且爆炸产生的冲击波速度越大越好;在常用的惰性气体中,Ar 气最适合作为发光工质;同一电路参数下,银电爆丝在常见金属中爆炸性能最好,铜丝其次;存在一个最佳的电爆丝长度,大概在300mm 左右;而且电爆丝根数也有一个最优值,在20根左右.研究所得结论与实验结果符合较好,对红外脉冲强光弹药研究具有重要意义.
Explores a new mechanism of using wire electric excitations to excite inert gas to generate intense plasma light and irradiates the optical ammunition. The explosion characteristics of electric burst wires are explored by using electric wire explosion adiabatic heating model and implosion excitation shock wave model in inert gas Theoretical analysis and numerical simulation.It is found that in order to obtain strong pulsed radiation, inert gas should be chosen as the luminescent working medium and the shock wave velocity produced by the explosion should be as good as possible. In common inert gases, Ar gas is most suitable as a luminescent working medium ; The same circuit parameters, silver wire explosion in the common metal in the best explosive performance, followed by copper wire; there is an optimal length of electric wire explosion, about 300mm or so; and the number of electric wire explosion also has an optimal value, At about 20. The conclusions obtained in the study are in good agreement with the experimental results and are of great significance to the research on IR pulsed light munitions.
