【摘要】：为检验铝纤维炸药的做功能力,对铝纤维炸药土中爆炸扩腔现象进行实验,并采用ANSYS/LSDYNA软件进行数值模拟,得出铝纤维炸药爆腔半径随药量变化的关系。结果表明,现场实验与数值模拟均能较好地表征铝纤维炸药土中爆炸扩腔的规律,铝纤维炸药相对于工业乳化炸药做功能力强,且由于其成型效果好等特点,应用于一些复杂的环境能够取得理想效果,可为类似工程提供参考。
[Abstract]:In order to test the work ability of aluminum-fiber explosive, the phenomenon of explosive cavity expansion in aluminum-fiber explosive soil was tested, and numerical simulation was carried out by using ANSYS/LSDYNA software. The relation between the radius of detonation cavity and the amount of charge was obtained.The results show that both the field experiment and numerical simulation can well characterize the law of explosive cavity expansion in aluminum fiber explosive soil. The aluminum fiber explosive has strong work ability compared with industrial emulsion explosive, and because of its good forming effect, etc.The application in some complex environments can obtain ideal results and provide reference for similar projects.
