分析了冲击波超压测试及TNT的等效威力,计算了爆炸高度及距离对超压测试结果的影响,给出了马赫杆对测试结果的作用,而这在以往的测试中经常被忽略。通过试验验证了提出的计算方法,两者之间的平均误差为3.1%。根据该计算方法,通过超压测试数据可以很方便地得到爆炸的等效TNT当量,从而直接为工程技术人员使用。
The equivalent power of shock wave overpressure test and TNT is analyzed. The influence of explosion height and distance on overpressure test results is calculated. The effect of Mach lever on test results is given, which is often neglected in previous tests. The proposed calculation method is verified by experiments, with an average error of 3.1%. According to this calculation method, equivalent TNT equivalent of explosion can be easily obtained by overpressure test data, which is directly used by engineering technicians.
