摘要

弹药爆炸过程中产生的地震波是评价弹药毁伤威力的重要技术指标之一。对弹药毁伤威力的评估和目标毁伤特性的研究具有重要意义。本研究分别以TNT炸药质量为1.25 kg、5.25 kg、10.5 kg和30.75 kg进行了实验研究,得到了不同测点的地面振动速度时程曲线。采用量纲分析法建立了地面粒子振动加速度与TNT炸药质量的函数关系,并通过实测试验数据验证了函数关系计算的准确性。结果表明:颗粒振动加速度峰值与TNT炸药质量呈正相关,与测点距离负相关;利用量纲分析法建立的粒子振动加速度计算函数对现有试验数据具有较高的拟合精度,可用于计算弹药爆炸地面振动加速度峰值。研究结果为爆炸地震波地面振动加速度峰值的高精度计算提供了一种方法。

Analysis of the ammunition explosion seismic wave propagation law
The seismic wave generated in the ammunition explosion process is one of the important technical indicators to evaluate the ammunition damage power. It is of great significance to evaluate the ammunition damage power and study the targets damage characteristics. In this study, experimental studies were carried out with TNT explosive mass of 1.25 kg, 5.25 kg, 10.5 kg and 30.75 kg, and the ground vibration velocity time-history curves at different measuring points were obtained. The functional relationship between ground particle vibration acceleration and TNT explosive mass was established by dimensional analysis method, and the functional relationship calculation accuracy was verified by the measured test data. The results show that the particle vibration acceleration peak value is positively correlated with the TNT explosive mass, and negatively correlated with the measuring point distance; The particle vibration acceleration calculation function established by the dimensional analysis method has high fitting accuracy for the existing test data, and can be used to calculate the ammunition explosion ground vibration acceleration peak value. The research results provide a high-precision calculation method for the peak value of explosion seismic wave ground vibration acceleration.
