摘　　要：针对爆炸温度场测量环境复杂、参数变化动态范围大和测量难度大的问题,提出了一种基于比色测温技术的爆炸场内部温度测量方法,并搭建了相应的爆炸场温度测量系统。该系统成功测试了由30kg甲、乙配方温压弹形成的火球温度场。研究结果显示,甲配方炸药爆炸最高温度达到2950℃,爆炸持续时间为420ms左右;而乙配方炸药爆炸最高温度可达3200℃,爆炸持续时间小于400ms,实现了对爆炸火球内部温度的测量。与传统的热电偶传感器相比,所提系统能够有效地获取爆炸火球内部温度,具有可行性。Considering the complex environment,large dynamic range of parameter variation and the difficulty in measuring explosion temperature fields,the inside temperature measurement method for explosion fireballs based on colorimetric thermometry technology was proposed and a corresponding temperature measurement system for the explosion fields was established.The system successfully tests the fireball’s inside temperature field produced by a 30 kg thermobaric bomb of Formula A and B.The results show that,the maximum temperature caused by the explosion of Formula A explosive can reach 2950℃together with an explosion duration of about 420 ms while that of Formula B explosive reaches 3200℃with an explosion duration of less than 400 ms;in this way,the inside temperature of the explosion fireball can be measured.Compared with traditional thermocouple sensors,this system can effectively obtain the inside temperature of the explosion fireball and has practical feasibility.
