  tnt equivalence
Results agree with previous observations that the concept of a single TNT equivalence value is inadequate to fully describe an explosive yield, rather TNT equivalence factor and overpressure duration should be presented as functions of radius.
      
Procedures are described by which the TNT equivalence factor can be calculated at any specified distance from a silver azide charge of known mass, or from a measurement of the shock radius and time, even when the charge mass is not known.
      
The TNT equivalence factor for silver azide was shown to vary from 0.3 to 1.4, depending on the distance from the centre of the explosion.
      
A new method of analysis was developed so that the charge mass and the TNT equivalence of an explosion could be derived from such a single radius-time measurement.
      
The pressure-radius profile was compared with that from a unit charge of TNT to determine the TNT equivalence of silver azide as a function of peak pressure and of distance from the centre of a silver azide charge.

The pressure distributions of explosion fields in air resulted from 2. 4 kg, 15 kgand 42 kg of TNT and rock emulsion explosives were respectively measured, and their pressurescaled distance relations consistent with the experiment results were also obtained by curve regression. The average TNT equivalence of the rock emulsion explosive based on the blast output wasderived as about 0. 708.

通过2.4kg、15kg、42kg量级的TNT和岩石型乳化炸药空中爆炸实验,利用曲线拟合法,得出了与实验结果吻合较好的TNT、岩石型乳化炸药空中爆炸的压力表达式,并求出了压力在10kPa~1000kPa时,该乳化炸药的TNT当量与对比距离的关系,在这个压力范围内,岩石型乳化炸药的TNT当量的平均值是0.708。

In this paper,the experimental techniques,which are used to calibrate the dynamic sensitivity of a measurement system on the scene and to measure the peak overpressure of blast wave,are improved.Compared to the traditional methods,these thchniques can give more reasonable accuracy.Using the techniques,we obtained the peak overpressure vs distance curve of blast wave for cylindrical charge containing aluminum AⅨ Ⅱ (80% by weight AⅨ Ⅰ plus Al power) surrounded by a thin steel shell and derived the over pressure’s TNT equivalence of the blast wave.The overpressure’s TNT equivalence of blast wave for three kinds of cylindrical charges,AⅨ Ⅱ,AⅨ Ⅰ (95% by weight RDX plus mix wax) and TNT,which are in the same size and mass,and surrounded by the same shell,are calculated by use of a simplified method.The comparison between calculating and experimental results indicated that the calculating result of AⅨ Ⅱ ,which is 1.15 times larger than AⅨ Ⅰ and 1.47 times larger than TNT,is in perfectly satisfactory agreement with the experimental data.

对爆炸波的现场测试系统动态灵敏度标定和峰值超压测量的实验方法进行了改进,显著提高了两者的测定精度。在此基础上,实验测定了两种不同尺寸的带薄钢壳钝黑铝柱形装药的爆炸波峰值超压随传播距离的变化关系,并由此推论出了爆炸波的超压TNT当量。简化计算了在相同壳体和装药质量条件下钝黑铝、钝化黑索金和TNT柱形装药爆炸波的超压TNT当量。计算和实验之间的比较表明:对于钝黑铝装药,超压TNT当量的计算值与实验值极好地一致;钝黑铝装药的超压TNT当量相对钝化黑索金和TNT装药分别提高了15%和47%。
