Abstract

In order to study the influence of the impedance matching and thickness distribution of the separator material on the impact initiation characteristics of the charged charge in the double-layer separator test, this paper uses a combination of theory and numerical simulation, and takes the two-layer separator of tungsten alloy and aluminum alloy as the research object. Based on the theory of detonation physics, the shock wave pressure, particle velocity, action time and shock wave energy model of the shock wave propagating to the delivered charge after the detonation of the main charge is attenuated by the tungsten alloy and aluminum alloy two-layer partitions are established. Theoretical and numerical simulation studies the influence of the total thickness of the partition (18mm~35mm), the order of the partition and the thickness distribution on the impact initiation characteristics of the charged charge.
