| 摘 要： | 利用声学近似原理,采用镜像法分析容器直径、注水深度、装药位置、容器顶底面以及侧壁约束等对水压爆破冲击波产生的最大超压及冲量的影响,通过采用压力传感器测量水压爆破底部固壁不同部位的压力波形和高速摄影测量物体的运动速度,对理论分析进行了验证。可以为类似水压爆破装药参数的确定提供依据。

| Abstract: | The dependence of overpressure and impulse on various parameters was discussed with a-coustic approximation and mirror image method for a liquid cylinder under different blasting conditions . Wall pressure and velocity measurements were carried out and it was found that the agreement was good between the theoretical prediction and experimental measurements, which showed a potential of engineering applications. |
