Abstract

The ConWep method is one of the most frequently used methods of modelling the effects of a blast wave impulse on a structure. The main goal of the study was to assess a TNT equivalent used in this approach. Six different methods to calculate this parameter for different explosive materials and charge shapes were analysed in this paper. The results error was lower than 20 % only when a TNT equivalent based on comparing the pressure impulses was used. This error can be lower only for spherical charges. In addition, for the tested distances (25 cm to 40 cm), TNT equivalents with an error margin of 5 % were assessed.

确定TNT当量标准的分析

ConWep方法是模拟爆炸冲击波对结构影响的最常用方法之一。这项研究的主要目的是评估在这种方法中使用的TNT当量。本文分析了不同炸药材料和装药形状下该参数的六种不同计算方法。仅当采用基于压力脉冲比较的TNT当量时，结果误差小于20%。只有球形电荷的误差才会小一些。此外，对于测试距离(25厘米至40厘米)，TNT当量的误差范围为5%。
