摘要
建立了一种评估炸药作功能力的新测试方法——金属薄板炸坑法,对典型高爆炸药、含铝炸药及含铝和高氯酸氨(AP)的混合炸药的作功能力进行了测试,并研究了铜薄板变形与炸药爆轰参数之间的关系。结果表明:金属薄板炸坑法能很好地测试各类炸药的作功能力,金属薄板深度和体积的TNT当量和综合考虑爆速和爆热贡献计算得到TNT当量的排序一致,测试相对标准偏差最大仅为1.17%。该方法简便、准确、实用,可广泛用于各种炸药的作功能力的测试与评估研究。
A new test method,metal sheet crater method,has been established for power assessment of high explo-sives,by which power of typical high explosive,aluminized explosive and composite explosive containing aluminum and AP was tested. The relationship between deformation of copper sheet and detonation parameters of explosive was also researched in this study. The results show that the metal sheet crater method can be a good test for evaluating the work ability of various explosives. The TNT equivalent of depth and volume of the metal sheet crater sorts the same order with the TNT equivalent calculated by detonation velocity and heat,with a lower relative standard deviations by 1. 17%. The method is simple,accurate,and practical which could be applied with satisfaction to the power determination of a variety of high explosives.
