摘要
Abstract
To study the gain of the non-central cluster-type warhead fragments velocity, the numerical simulation of the cluster-type directional warhead detonation dispersion process was porformed by LS-DYNA. The simulated results were in good agreement with the test results. The results showed that in comparison with center priming, on the relative direction of detonation location the fragment gain speed in the eccentric warhead detonation zone increases significantly. The maximum gain achieves 10. 7 percent. The same side fragment speed of flash point was less significantly than that of opposite side fragment. When azimuth at 0°to 180° direction, the pace of fragmentation reveals an increasing trend.关键词
