摘要

摘要: HL-10炸药是一种以RDX为基的含铝炸药，为了研究该炸药在子弹或金属破片撞击作用下的安全性，利用12.7 mm机枪法对钢壳包覆的柱形HL-10装药进行了枪击试验，试验结果表明，炸药没有发生燃烧或爆轰现象，由此可定义该炸药的枪击感度试验反应等级为1级。建立了炸药枪击试验的计算模型和数值计算方法，对子弹撞击和穿透炸药过程进行了三维数值模拟计算，计算结果与试验结果相符，分析了子弹速度对HL-10炸药枪击感度的影响，其结果可为炸药安全性评价分析提供理论根据。为了进一步验证计算模型和方法，对美国的PBX-9404炸药的枪击作用过程进行了计算分析，结果表明，PBX-9404炸药在枪击作用下发生了完全爆轰反应，与Neff等人的试验结果相吻合。

Abstract: HL-10 explosive is an aluminized explosive based on RDX. In order to investigate the safety characteristics of HL-10 for bullet impact test, 12.7 mm bullet was used to impact HL-10 charge. Experimental results show that there is no significant reaction or burning resulted from these bullet impact tests, so the impact sensitive of HL-10 for bullet impact test is defined as the first grade. The calculation modes and methods of bullet impact tests were established. The three-dimensional numerical simulations of the bullet impact tests were conducted. Good agreement was found between the calculated results and the experimental results. In addition, the responses of HL-10 to different bullet impact velocities were analyzed. The calculated results can provide a theoretical basis for the analysis of explosives safety evaluation. To further verify the calculation model and method, the bullet impact test calculation for America PBX-9404 explosive was conducted. The results show that, PBX-9404 explosives would be detonated at 850 m/s impact velocity for the same calculation mode, which are consistent with Neff and others experimental results.
