摘要
为了研究非理想炸药的做功能力,对TNT、PBXN-109、AFX-757和CL-20基炸药进行了混凝土介质内爆炸实验,测量了实验炸药爆炸形成的混凝土腔体容积,通过量纲分析和实验数据建立了混凝土腔体容积的计算模型,并采用自行设计的混凝土腔体容积方法评价了炸药的爆炸做功特性。结果表明,混凝土腔体容积法能够用于评估非理想炸药的做功能力,单位质量同类型炸药的混凝土腔体容积基本一致。混凝土腔体容积与炸药能量(或炸药质量与爆热的乘积)存在线性关系,炸药混凝土中内爆炸的相对做功能力可以通过爆热当量确定。
In this study we carried out internal blast tests on TNT,PBXN-109,AFX-757 and CL-20 based explosives and measured the concrete cavity volumes of several explosives tested to study the characteristic work capability of non-ideal explosives. A calculation model of the concrete cavity volume was established on the basis of dimensional analysis and experimental dada. The characteristic work capacity of test explosives was evaluated using self-designed concrete cavity volume method. The results show that the concrete cavity volume can be used to evaluate the work capability of non-ideal explosives. The concrete cavity volume and the explosive energy( or detonation heat) forms a linear relationship. The relative work capacity of the explosive in concrete can be determined by the TNT equivalent of the detonation heat.
