JHL-3、A-IX-2和TNT三种炸药水下爆炸冲击波特性测试研究

摘要

Under the same test conditions, the characteristic parameters such as shock wave pressure and time reduces constant of JHL-3, A-IX-2 and TNT were discussed based on test data of explosion underwater. The underwater explosion powers of different types of explosives were also compared. Results indicate that the shock wave pressure varied with explosion density, explosion type and distance to explosion. Under equivalent TNT mass and near to explosive source, the peak pressure and power of JHL-3 was the biggest, while the time constant changed little.%在相同的试验环境下,对JHL-3、A-IX-2和TNT三种炸药进了水下爆炸试验,并在测点和测量仪器相同的情况下完成数据测量,对3种炸药水下爆炸时的冲击波压力、时间衰减常数等特性参数进行了对比分析,比较了不同类型炸药的水下爆炸威力.结果表明:炸药爆炸威力随炸药的装药密度、炸药种类及爆炸距离的不同而变化；在近距离处和相同TNT当量下,炸药JHL-3压力峰值最大,威力也最大,而3种炸药的时间常数相差不大.
