摘    要:测量了TNT、IH18、WD40三种炸药在密闭容器内爆炸的壁面反射冲击波超压,得出冲击波超压-时间曲线图,比较了三种炸药在同一半径处冲击波超压的差异,分析了造成差异的原因。结果表明,炸药爆炸时向外抛撒的固相物质对近场传感器的冲击作用会影响超压测量结果。采用单点测量数据描述近场冲击波超压存在局限性,近场试验时应多点测量,统计描述。

关 键 词:冲击波超压、多点测量、密闭容器、冲击作用

Abstract:Wall reflection shock wave overpressure value of TNT, IH18 and WD40 charge in a closed container were measured, overpressure curve obtained. Companioned the overpressure between different channels at the same radius, reasons are analyzed. The results showed that the solid phase material throwed out by explosive impact on the role of near-field sensor will affect the overpressure measurements. Described using single-point measurements of near-field blast overpressure have limitations. Near-field testing should be multi-point measurement, and use the knowledge of mathematical statistics to describe it.
