【摘要】 针对端面起爆柱形装药水中爆炸近场冲击波阵面呈现非球形传播的特点,采用分幅相机记录了炸药起爆36μs内近场冲击波的传播情况,分析了冲击波在不同时间和不同位置处的形状;采用两台高速扫描相机测量了侧边任意一点的冲击波速度,进而得到冲击波阵面压力。进行了解析求解,并结合数值计算进行了参照比较,得到的结果基本一致。更多还原

【Abstract】 According to the non-sphericity characteristic of shock wave surface at close-field after cylindrical charge with end boost exploring under water, the propagation of shock near-field is recorded by frame camera within 36 seconds after blasting, the shape of shock on diverse time and situation is analyzed. The shock pressure of arbitrary point on the side of charge is measured through two streak cameras, the resolution is compared with numerical value. It proved that they are consistent relatively.更多还原
