摘要
冲击波压力是评估炸药爆炸效应的重要参数,冲击波压力的特征与装药形式和起爆方式密切相关。介绍了带壳装药热爆炸模式下的装药周围空气中的冲击波超压的测量方法和测量结果,并结合爆室结构,对结果进行了深入分析。带壳装药爆炸时,由于电动效应及爆炸产物和壳体之间的摩擦,会产生电磁辐射,且电磁辐射信号持续时间和复杂程度与裸露炸药爆炸时有明显的区别。
The explosive shock wave pressure is an important parameter which is used for the evaluation of explosion effect,and the characteristic of shock wave pressure is closely related to charge and detonation mode.A measurement method and the results of overpressure of charge with shell measured in the case of thermal explosion were described,and the results were analyzed according to the structure of explosive cave.The results show that the electromagnetic radiation is emitted due to the electrokinetic effect and the friction between explosion product and shell when the charge explodes,and the signal duration and complexity of electromagnetic radiation generated by the charge with shell are different from those generated by the bare charge.
