Explosion-Electricity Coupling Effect of RDX Plastic Explosive

In order to find a new way to improve the output performance of explosives, the coupling of external electrical energy and explosive energy of the explosive itself was studied. At the same time, an explosion-electricity coupling (EEC) device was designed and set up, and a flat RDX plastic explosive was selected as the research object. The detonation velocity measured by the detonation velocimeter and the detonation pressure measured by the photonic Doppler velocimetry were used as the main characteristic parameters of the EEC gain to study the effect of the EEC on the output performance of the explosive. By analyzing the electrical properties of explosives in the process of EEC, the reaction process of EEC was qualitatively analyzed, and the possible mechanism of the EEC of RDX plastic explosives was proposed. The research results show that the EEC can effectively deposit electrical energy in the explosive reaction zone. In the premise of ensuring the same other conditions, the EEC can increase the detonation velocity, von Neumann spike pressure and Chapman-Jouguet pressure of RDX plastic explosives to a certain extent. The above work puts forward a way to enhance the output performance of explosives through theoretical and experimental research on EEC, which has a certain theoretical value and guiding significance for the research on the enhancement of explosive performance in the future.
