摘要
为研究炸药爆炸产物的热毁伤作用,根据塞贝克(Seebeck)效应和传热学原理,利用WRe5/26热电偶对TNT爆炸产物进行了温度响应测试,包括自由场实验和半密闭空间实验,获得了相应的温度曲线,分析了影响热电偶响应的因素。结果表明,WRe5/26热电偶能够反映爆炸产物的热输出特性,热电偶的指示温度与爆炸产物温度之间存在迟滞,热流密度是评价热毁伤威力的重要参数。
In order to investigate the hot destruction of explosive products, the temperature response test of TNT explosive products, including explosive experiments in free field response and the half-airtight space, is carried out by WRe5/26 thermocouple according to Seebeck effect and heat transfer theory principle. The relative temperature curves are obtained and the factor affecting the response of the thermocouple is analyzed. The results show that the WReS/26 thermocouple can reflect the heat output of explosive products. There is a lag time between the thermocouple＇s response temperature and the explosive products temperature. The heat flux density is an important parameter to evaluate the hot destruction.
