摘要
用地面和空中冲击波超压测试系统测定了TNT和B炸药爆炸的马赫反射波超压和入射冲击波超压,计算得到不同测试条件下TNT爆炸冲击波超压的经验公式和B炸药的TNT当量。结果表明,马赫反射波超压大于入射冲击波超压,马赫反射波超压与入射冲击波超压比值随实验中对比距离的增加而增加。由马赫反射波超压和入射冲击波超压计算得到的B炸药TNT当量比分别为1.40和1.32。认为以空中入射冲击波超压测试结果计算得到的TNT当量更真实。
The overpressures of Mach reflection wave and incident shock wave of TNT and composition B were measured using both ground and air shock wave overpressure test systems. The empirical formulas of shock wave overpressure of TNT and the TNT equivalence of composition B under different test conditions were obtained via calculation. The results show that the overpressure of Mach reflection wave is higher than that of incident shock wave. The specific value of Mach reflection wave overpressure with incident shock wave overpressure rises with the increase of the scaled distance in this experiment. The TNT equivalences of composition B obtained via calculation of Mach reflection wave overpressure and incident shock wave overpressure are 1.4 and 1.32, respectively, considering that the TNT equivalence obtained through the incident shock wave overpressure is more believable.
