| 摘 要： | 将温压药柱放在自行设计的两个相互连接的密闭和半密闭房间,测试了在有限空间内爆炸冲击波的传播特性.通过试验和数值计算,得到距炸点不同距离处的超压曲线.结果表明,与开阔空间不同,密闭空间的超压曲线由多峰构成,经分析发现这是由于密闭空间的结构造成的.采用LS-DYNA有限元程序通过与三维数值模拟分析了爆炸冲击波在有限空间内的传播过程,计算结果与试验结果一致.

| Abstract: | The connected limited and limitless space are designed and the propagation characteristics of shock wave that generated by thermobaric column exploding in limited space is tested.The overpressure curves in different distances are obtained by experiment and numerical simulation.The results show that the overpressure curve of limited space has many peaks,which is different from overpressure curve of limitless space that has only one peak.This phenomenon is caused by the structure of limited space.Through thre... |
