摘要: 本文改进了一种二维锰铜一康铜环型拉氏量计,测量了雷管内部二维冲击起爆(SDT)流场;还应用二维程序2DLF和BKW程序对雷管SDT过程进行了二维数值模拟。实验结果和模拟结果作了对比,使二维拉氏量计和二维程序2DLE对研究雷管SDT可行性相互作了检验。为研究雷管和小直径炸药柱二维SDT过程提供了一种研究方法。

Abstract: The 2D initiation flow in a detonator is measured using an im?proved 2D composite manganin-constantan ring gauge. The SDT of the de?tonator is simulated with the codes 2DLE and BKW. Feasibility of the 2D Lagrangian gauge and the code 2DLE in research applications concerning de?tonators is verified through comparison of experimental data and computed results.
