Abstract
A device of simulating drop test was designed to study the safety drop of Ф98 mm x39 mm PBX-2 explosive under the shell confinement. Фhe pressure change was measured by PVDF gauges. Acceleration change at two positions were obtained by PCB acceleration gauges. Ignition process was analyzed by high-speed motion pictures. The reaction overpressure was measured by blast pressure gauges. Reaction of explosive was obtained from different velocity fragment impacts. Results show that the relative release energy for PBX-2 explosive is about 35％, which is higher remarkedly than that in Spigot test, and the test established to simulate drop can provide a new means to evaluate explosive safety under the unexpected scenarios.关键词
