冲击作用下 PBX 炸药预制孔洞塌陷过程的实验探索
Experiment of Cavity Collapse Process in Plastic-Bonded Explosives under Shock Loading
摘要
Abstract
The origin,ignition and growth of hot spot are keys to understand the shock initiation in heterogeneous explosive.An experimental method of shock behavior for millimeter-scale plastic-bonded explosives (PBX)is developed by using an electrical explosion driven low-velocity flyer,a quick-response thermocouple and a high speed and micro-scale camera,in which the camera consists of a microscope,a high speed camera and an image transmission bunch.The dynamic collapse process of the precast cavity with a diameter of 0.5 mm in PBX is captured.The physical image and temperature curve of the precast cavity in PBX are obtained during the dynamic collapse process,which may pro-vide a foundation for the hot spots experiment in PBX.关键词
