Title The research of Magnetic field on explosive magnetic field of metal explosive
Abstract
Explosive detonation is a complicated physical process, which is often accompanied by heat release and discharge.. The classical detonation physics is mainly based on thermodynamics, and the electromagnetic pulse phenomenon is an important part of the explosion, and has not been studied deeply.. Through theoretical calculation, numerical simulation and experimental study, the electromagnetic pulse electromagnetic parameters of the explosive are studied and measured..
Firstly, on the basis of plasma physics principle analysis of the detonation electromagnetic pulse generating mechanism; through the plasma radiation electromagnetic pulse of the mathematical model analysis of the detonation the relationship between parameters and the parameters of the electromagnetic field; according to Maxwell equations and the numerical method for the description of the electromagnetic field distribution.
Secondly, the electromagnetic pulse test system is designed and processed on the basis of theoretical analysis, and the reliability of the system is verified by the standard pulse generator..
Finally, the design of the aluminized explosives detonation electromagnetic pulse test, through the five sets of experiments to capture frequency 0.1MHz about electromagnetic pulse, verify the explosive containing metal explosion electromagnetic pulse of authenticity. Analysis of experimental results, we come to the conclusion: electromagnetic pulse signal intensity with the same quality of explosive metal content and the same metal explosive content is proportional to the mass, the distance between the test antenna and inversely proportional.
It is hoped that the results of this study can provide a reference for the electromagnetic field in the detonation process..
