High Quasi-static Pressure Measurement of Explosion in Closed Container

Abstract To develop a method for determining the parameters of final equation state (EOS) detonation products aluminized explosives, an explosion quasi-static pressure measurement system in closed containers with large mass-to-volume ratio is developed. The influence domestic and foreign typical charge piezoelectric sensors, sensor buffer adjustment structures, container tightness, grounding operation, weather, other factors on long-time high are comparatively studied. test methods conditions obtaining standard pressure-time curves clarified. mass different explosives static obtained. result shows that 113B03 type more suitable measuring leakage effect humid environment. An appropriate structure reliable operation can significantly reduce high-frequency oscillation signal.
