【摘要】：研發(fā)了一種內(nèi)襯PVC殼體,外裹泡沫陶瓷殼體的新型空殼顆粒作為人防結(jié)構(gòu)分配層。通過大比尺化爆實驗,研究了爆炸載荷下新型空殼顆粒分配層人防結(jié)構(gòu)和普通黃沙分配層人防結(jié)構(gòu)的破壞情況和沖擊波傳播規(guī)律。實驗證明:同樣當(dāng)量爆炸載荷下,相對黃沙分配層,新型空殼顆粒分配層可以降低應(yīng)力峰值50%左右;相對常規(guī)空殼顆粒,新型空殼顆粒分配層受損情況顯著減小。這表明:新型空殼顆粒作為人防工程的分配層兼具顯著的削波耗能效果和抵抗二次爆炸的能力,因此可以提高人防工程的抗爆能力,具有廣闊的軍事應(yīng)用前景。
[Abstract]:A new type of hollow shell with PVC lining and foam ceramic shell was developed as the distribution layer of civil air defense structure. Based on the experiments of large scale explosion, the damage and shock wave propagation of the civil air defense structure with a new type of empty shell particle distribution layer and the ordinary yellow sand distribution layer are studied. The experimental results show that the stress peak value of the new shell particle distribution layer can be reduced by about 50% compared with the yellow sand distribution layer under the same equivalent explosion load, and the damage of the new shell particle distribution layer is significantly reduced compared with the conventional empty shell particle. The results show that the new shell particles as the distribution layer of civil air defense project have the remarkable energy cutting effect and the ability to resist the secondary explosion, so they can improve the anti-explosion ability of civil air defense engineering and have a broad prospect of military application.
