摘要
爆炸地震波对于评估弹药的毁伤威力具有极其重要的意义,为了测试云爆弹爆炸后产生地震波的振动强度,需要设计合理的测试方案,准确测量弹药爆炸后地震波的数据,并分析其衰减特性,从而得到爆炸地震波分布规律.该论文在实际的爆炸场环境中,采用相应的地震波传感器及测振仪,按照合理的测试方案,测试弹药爆炸产生的地震波,并对数据进行分析,分析结果表明:云爆弹在爆炸时产生的地震效应非常强烈,并且随着距离爆心距离的增大,地震波的衰减速度也明显加快;利用质点振动速度理论公式对实测地震波进行拟合分析,拟合函数关系式在反映爆炸地震波的振速分布状况中与实际测试数据对比具有良好的一致性,可以将其运用到爆炸场毁伤测试中,为测试数据的准确性提供理论评判依据.
Explosive seismic waves are of great significance for assessing the damage power of ammunition.In order to test the vibration intensity of seismic waves after the cloud bomb explosion,a reasonable test plan needs to be designed to accurately measure the data of seismic waves after ammunition explosion and analyze its attenuation characteristics,so as to obtain the distribution of explosion seismic waves.This paper uses the corresponding seismic wave sensors and vibrometers in an actual explosion field environment to test the seismic waves generated by the ammunition explosion in accordance with a reasonable test plan and analyze the data.The results show that the seismic effect of cloud bomb explosion is very strong,and as the distance from the center of the explosion increases,the attenuation speed of the seismic wave is also significantly accelerated,and the theoretical vibration velocity formula is used to fit and analyze the measured seismic wave.The relation of the fitting function has good consistency with the actual test data in reflecting the vibration velocity distribution of the explosion seismic wave.And it can be applied to the explosion field damage test to provide a theoretical evaluation basis for the accuracy of the test data.
