Abstract

In order to study the energy release law of a charge with a non-circular cross-sectional structure under the influence of initiation modes, the energy release characteristics of the charge with a non-circular cross-sectional structure under different initiation modes were calculated by AUTODYN simulation software, then effects of initiation modes on the evolution of detonation waveforms, and masses and initial velocities of fragments were analyzed. The results show that, due to particularity of the charge’s structure, energy distribution of the charge is uneven when using single-endpoint initiation, which results in a large number of invalid fragments with small masses in some areas, and a large fluctuation of initial velocities of fragments at different positions. When the two-endpoint and three-endpoint initiation modes are adopted, the detonation energy is homogenized, the number of invalid fragments is reduced, and the consistency of fragments’ initial velocities is improved. It proves that the energy output structure of a charge with a non-circular cross-sectional structure could be effectively regulated by adjusting the initiation mode, and the circumferential energy field could be homogenized.
