| 摘 要： | 通过自制的有机玻璃压导探针,对炸药、有机玻璃和水中的爆轰波和冲击波进行连续测量,得到了爆轰波和冲击波的时间历程演化曲线。由此计算出炸药爆速、有机玻璃和水中冲击波速度随时间的变化曲线;再由有机玻璃和水的冲击雨果尼奥关系式和动量定理,计算得到了炸药爆压、有机玻璃和水近场冲击波速度、压力变化曲线。结果表明:理论计算结果与有机玻璃和水的冲击波和炸药爆压试验结果基本吻合,能够准确反映冲击波在有机玻璃和水中的衰减规律。

| Abstract: | Detonation waves and shock waves in explosive,polymethyl methacrylate (PMMA) and water were measured continuously by a new in-house made PMMA pressure probe to obtain time history curves of detonation wave and shock wave.The detonation velocity of explosives and velocity-time curves of shock wave in PMMA and water were calculated.Further,the near field explosive detonation pressure and speed curves of shock wave in PMMA and water were obtained by Hugoniot equation of PMMA and water and theorem of momentum.Theoretical calculation results agree well with the experiment,which can accurately reflect the attenuation law of shock wave in PMMA and water. |
