摘要
Abstract
In the existing sensitivity testing methods,characteristic drop height method can only obtain the charac-teristic 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 probabili-ties.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 mechani-cal 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.关键词
