- Abstract
In order to solve the problem that the D-shaped section warhead has a poor uniformity of the energy output, this paper designs and optimizes a multi-point initiation method. Based on the AUTODYN finite element numerical simulation, the propagation of the detonation wave in the D-shaped section warhead is studied under different initiation modes, and velocity and spatial distribution of the fragments are analyzed. Moreover, the effect of different cross-sectional shapes on the uniformity of the energy output of the charge is studied, and, under the optimal initiation mode, the effect of different length-diameter ratios on the energy output of the charge is discussed. The research results show that, compared with the single-point initiation, under the three-point initiation mode, the fragment velocity is up to 615 m/s, and the dispersion synchronization increases by 60%. As the symmetry of the profiled shaped section increases, the uniformity of the energy output of the charge significantly improves. With the increase of the length-diameter ratio, the average velocity of the fragments in the middle of the warhead increases by 67. 4%, and the dispersion synchronization increases by 56.6%. In addition, the energy utilization rate of the charge increases.
