摘要/Abstract

摘要： 为准确分析梯恩梯炸药在密闭空间中的爆炸载荷，在统一设施标准模型和基于能量守恒的简化计算公式基础上，提出了一种计算爆炸产物后燃烧能量的方法。该方法应用到基于有限元分析软件ANSYS/AUTODYN平台的数值模拟中，实现负氧平衡炸药在密闭空间中爆炸过程的数值仿真计算。计算结果与试验测试结果表明：梯恩梯炸药在密闭空间中发生爆炸时，其爆轰产物的后燃烧效应不可忽视；不考虑爆炸产物的后燃烧效应，数值计算得到的准静态压力较试验值低55%以上，50 ms内冲量较试验值低49%以上；将爆轰产物的后燃烧能量计入后，爆炸压力及冲量时程的计算值与试验值吻合较好，为结构受爆炸载荷响应分析提供了准确的输入载荷。

Abstract: An approach to determine the afterburning energy in ANSYS/AUTODYN simulation is presented based on the unified facilities criteria model and a simplified formula according to the conservation law of energy released in the explosion process. A numerical simulation of TNT explosion in confined space was conducted. The calculated and experimental results show that the afterburning effect of TNT detonation products has a significant influence on the confined blast load. The calculated quasi-static pressure and impulse within 50 ms without considering the afterburning effect of detonation products are 55% and 49% lower than the experimental data, respectively. When the afterburning energy is taken into account, the calculated values of explosive pressure and impulse time history show a good agreement with the experimental data. The proposed method would provide accurate input load for predicting the dynamic responses of structures subjected to confined explosion. Key

Key words: explosionload, confinedspace, afterburningeffect, quasi-staticpressure
