火球动态模型在温压炸药热毁伤效应评估中的应用

Applicationofadynamicmodeltothermaldamageestimation ofthermobaricexplosives

摘要: 根据红外热成像仪所测的某温压炸药和TNT爆炸火球的表征参量数据,分析了火球热辐射的动态模型,对爆炸火球变化规律进行了定量描述。以具有时间属性的爆炸火球热辐射动态模型为基础,比较了温压炸药和TNT装药爆炸火球热毁伤效应。研究结果表明,温压炸药的热辐射剂量可达TNT 热辐射剂量的3.6~4.8倍,温压炸药具有明显的高温毁伤优势;与静态模型相比,动态模型能用来更好地模拟火球的动态变化过程,更合理地评估炸药的热辐射毁伤效应。
