Abstract
In order to study impact safety of unheated and heated PBX-2 explosives, the test system of heat and projectile impacting mulitiple was designed. The multiple tests utilized Φ50 mm × 50 mm PBX-2 explosive as the test samples, the temperature at different positions was tested by thermocouples. Ignition reaction process was analyzed by high-speed motion pictures. The reaction overpressure of explosive was gained by shockwave overpressure gauges. The impact response characteristics for PBX-2 explosive were gained initially for unheated and heated PBX-2 explosives. The results show that impact reaction threshold velocity for heated PBX-2 decreased more significantly than unheated PBX-2 explosive. This heat and dynamic loading combined test methods establisted can provide a new way to assess the explosives safety under abnormal environment.关键词
