温压炸药内爆炸压力特性及威力试验研究

为研究温压炸药内爆炸压力特性和威力，基于爆炸相似律与理想气体状态方程分析建立了冲击波超压及准静态压力计算模型，并利用爆炸罐开展了温压炸药和梯恩梯（TNT）炸药裸药柱内爆炸试验。结果表明：内爆炸压力效应包括冲击波压力和准静态压力，准静态压力上升伴随着冲击波的多次反射，反射结束后准静态压力上升到峰值并维持较长时间；温压炸药内爆炸冲击波超压峰值和准静态压力峰值较TNT炸药分别提高了18.0%和62.9%，基于内爆炸冲击波超压和准静态压力计算得到的温压炸药TNT当量分别为1.18和1.63.

Experimental Study of the Characteristics of Internal Explosion Pressure and Power of Thermobaric Explosive

In order to study the internal explosion overpressure and power of thermobaric explosive (TBX), the calculation models of shockwave overpressure and quasi-static pressure are established through the theoretical analysis. TBX and TNT grains are tested in explosion vessel. The result shows that the pressure effect induced by internal explosion includes shockwave overpressure and quasi-static pressure. The rise of the quasi-static pressure is accompanied by the multiple reflections of shockwave. When the reflection is over, the quasi-static pressure goes up to the maximum and lasts for a relatively long time. The overpressure peak and quasi-static pressure peak of TBX are increased by 18.0% and 62.9%, respectively, compared with TNT. The TNT equivalents of TBX which are calculated based on overpressure and quasi-static pressure are 1.18 and 1.63, respectively.
