摘要:
在现有的感度试验方法中，特性落高法只能得出50%爆炸概率的特性落高，BAM试验结果只能得出临界撞击能量和载荷压力，而兰利-D最优化法能够得到不同发火概率下的机械感度。因此，采用兰利-D最优化法，研究CL-20在机械作用下的不同发火概率临界反应阈值及温度对临界反应阈值的影响。使用BAM撞击和摩擦感度仪，对ε型CL-20开展机械感度阈值研究；采用特性落高法和兰利-D最优化法，研究撞击能量阈值；采用BAM摩擦感度试验和兰利-D最优化法，研究载荷压力阈值。通过兰利-D最优化法，得到了CL-20在1%、0.000 1%-发火概率下的撞击能量阈值和载荷压力阈值，分析了火炸药1%、0.000 1%发火概率在实际安全生产中的应用。结果显示：30、 60 ℃和90 ℃温度下，采用特性落高法得到CL-20的50%发火概率的撞击能量阈值E50分别为2 434.32、 2 215.11、 1 955.36 mJ，兰利-D最优化法所得E50分别为2 504.40、 2 297.15、 2 014.63 mJ，撞击感度随温度的上升呈现升高趋势；采用BAM试验得到CL-20的载荷压力分别为64、 56、 48 N，兰利-D最优化法得到50%发火概率的载荷压力阈值p50分别为100.35、 92.77、 78.86 N，摩擦感度随着温度的上升同样呈现升高趋势。
Abstract:
In the existing sensitivity testing methods, characteristic drop height method can only obtain the characteristic drop height with a 50% probability of explosion H50, BAM test results can only obtain the critical impact energy and load pressure, while Langlie-D optimization method can obtain the mechanical sensitivity under different ignition probabilities. Therefore, the critical reaction threshold of CL-20 with different ignition probabilities under mechanical action and the influence of temperature on the critical reaction threshold were studied using Langlie-D optimization method. The mechanical sensitivity threshold of ε-type CL-20 was studied by BAM impact and a friction sensitivity meter. The impact energy threshold was studied by characteristic drop height method and Langlie-D optimization method. The load pressure threshold was studied by BAM test and Langlie-D optimization method. The impact energy threshold and load pressure threshold of CL-20 at 1% and 0.000 1% ignition probabilities were obtained by Langlie-D optimization method. And the application of 1% and 0.000 1% ignition probabilities of explosives in practical safety production was analyzed. The results show that, at 30, 60 ℃ and 90 ℃, the impact energy threshold E50?for the 50% ignition probability of CL-20 obtained by characteristic drop height method is 2 434.32, 2 215.11 mJ and 1 955.36 mJ, respectively. E50?obtained by Langlie-D optimization method is 2 504.40, 2 297.15 mJ and 2 014.63 mJ, respectively. The impact sensitivity shows an increasing trend with the rise of temperature.The load pressure of CL-20 obtained by BAM method is 64, 56 N and 48 N,respectively.The load pressure threshold??p50?for 50% ignition probability obtained by Langlie-D optimization method is 100.35, 92.77 N and 78.86 N, respectively. The friction sensitivity also shows an increasing trend with the rise of temperature.
