The response effect and rule of an electro-explosive device(EED) in an electromagnetic wave environment are the basis of research on electromagnetic safety and environmental adaptability design.To get the response rules and some important parameters affecting the EED response, the relationship between the induced current and frequency in the electromagnetic environment of electro-explosive device was studied by using a continuous electromagnetic wave environment simulation system and an induced current testing device established in the laboratory. Results show that there is a resonance relation between the induced current and the electromagnetic wave frequency of EED.Taking EED vertical leg wire state as a sample, when the length of EED leg wire is 072 mm, corresponding induced current resonance frequency is about 200 MHz.The theoretical calculation and simulation study performed on the basis of these results prove that the artenna characteristics of EED leg wire are the key factors that affect the electromagnetic response.The maximum induced current is at the resonance frequency point corresponding to the length of EED leg wire.
