摘要
Abstract
In order to reveal the detonation propagation characteristics of the new melt-cast matrix 3,4-dinitro-phyrazole(DNP),a two-dimensional axisymmetric numerical calculation model of cylindrical charges was established.The propagation process of the detonation wave of DNP explosive was numerically simulated using calibrated parameters of the ignition-growth reaction rate equation.Additionally,the critical diameter of DNP melted explosive was measured using the continuous wire method.The results show that the calculated critical diameter of DNP explosive is 8.20 mm,and the mea-sured critical diameter of DNP explosive is 7.88 mm.The calculated values are in good agreement with the experimental values.By combining experiments with numerical simulations,the critical diameter of DNP melt-cast explosives can be studied,which can provide reference for the formulation design and warhead structure design of DNP explosives.关键词
