Abstract
In order to guide the structural design of the micro-explosive train, the JWL equation of state parameters of the primer explosive PbN6 is fitted first, and then the simulation model of the flyer driven by micro-charge and the flyer impacting the explosion-proof component is established using AUTODYN software. The effects of charge height, flyer thickness, and shear plate aperture on flyer velocity and kinetic energy are obtained by simulation calculation. When the charge diameter is fixed, the flyer velocity increases first with the increase of charge height, and then gradually tends to a fixed value. When the charge size is fixed, the maximum flyer kinetic energy corresponds to an optimal flyer thickness. When the shear plate aperture is smaller than the charge diameter, the flyer velocity will be improved. The relationship between the thickness of nickel, copper, and silicon explosion-proof component and shock wave attenuation is studied quantitatively, and the safe explosion-proof thickness of initiating JO-9C acceptor charge is given.
