真实空气中TNT装药爆炸近区冲击波传播特性研究

摘要

Based on the explosion theory of point source, this study obtains the solution of a strong explosion of one-dimensional TNT point source charge, line source charge, and plate source charge blasting in a close-in flow field. Furthermore, this study investigates the propagation characteristic in the close-in field of a shock wave of the TNT spherical charge explosion in real air condition by using the dimensional state equations of real air and the detonation products of a TNT spherical charge. Based on the analysis of the exam-ples, the study results are largely consistent with that of some existing literature. These research results provide an important reference for studying explosion mechanics and protection engineering.%本文基于点源爆炸理论,建立了面源、线源和点源TNT装药强爆炸解,填补了面源与线源强爆炸解的空白;采用真实空气状态方程进行分析计算,研究了真实空气条件下球形TNT装药爆炸近区冲击波的传播特性.通过算例分析,计算结果与已有文献资料数据吻合较好.本文的研究成果对爆炸力学和防护工程研究起到了重要的参考作用.
