A new velocity probe which permits recording the time history of detonation and shock waves has been developed by improving the commercial on principle and structure. A method based on the probe is then designed to measure the detonation velocity and near-field shock parameters in a single underwater explosion, by which the oblique shock wave front of cylindrical charges and the peak pressure attenuation curve of spherical explosive are obtained. A further derivation of detonation pressure, adiabatic exponent, and other shock parameters is conducted. The present method offers a novel and reliable parameter determination for near-field underwater explosion.
通过在原理和结构上对商用产品进行改进,研制出了一种新型速度探针,可用于记录爆轰波和冲击波的时间历程。然后,基于该探针设计了一种方法,用于测量单次水下爆炸中的爆速和近场冲击参数,由此获得了柱形装药的斜冲击波阵面和球形炸药的峰值压力衰减曲线。还对爆轰压力、绝热指数和其他冲击参数进行了进一步推导。该方法为近场水下爆炸提供了一种新颖且可靠的参数测定方法。
