ABSTRACT

Recently Vandersall et al. [1] reported a series of shock initiation experiments using embedded manganin pressure gauges in the plastic bonded explosive (PBX) LX-14 (95.5% HMX and 4.5% Estane by weight) plus Ignition and Growth (I & G) simulations of all the gauge records. Jones et al. [2] reported a study of LX-14 using embedded particle velocity gauges in a similar shock strength range. It is prudent to test the ability of a reactive flow model to predict both types of gauge results. The I & G LX-14 model parameters based on the pressure records are compared to five sets of particle velocity gauge records. Excellent agreement was obtained with all five particle velocity experiments, implying that the two types of gauges yield equivalent results and that either technique can be used with the I & G model.

摘要

最近 Vandersall 等人。[1] 报道了在塑料粘结炸药 (PBX) LX-14（按重量计 95.5% HMX 和 4.5% Estane）中使用嵌入式锰压力计进行的一系列冲击引发实验，以及所有爆炸物的点火和生长 (I & G) 模拟。仪表记录。琼斯等人。[2] 报告了在类似的冲击强度范围内使用嵌入式粒子速度计对 LX-14 的研究。谨慎地测试反应流模型预测两种类型的仪表结果的能力。将基于压力记录的 I & G LX-14 模型参数与五组粒子速度计记录进行比较。所有五个粒子速度实验都获得了极好的一致性，这意味着这两种类型的仪表产生等效的结果，并且任何一种技术都可以用于 I&G 模型。
