Description
Summary:A numerical simulation was employed to investigate the influence of initiation modes on the energy output structure of cylindrical explosives. Based on the numerical simulation results of the response behaviours of identical explosive configurations under different initiation scenarios, including one-end initiation, two-end detonation, centre point detonation, and axial detonation, combined with the development and propagation rules of detonation waves as well as the response behaviour of the shell, the temporal and spatial distribution characteristics of the output energy distribution of explosives under various initiation modes were obtained. The research findings provide a theoretical foundation for the design of explosive initiation points, the regulation of the directional energy output of warheads, and the enhancement of energy utilization efficiency.
