摘要

To meet the detonation control requirements of the aimable warhead in cooperation with the fuze, a detonation control modeling method based on octagon laser fuze detection and positioning is proposed to study the dispersion rule of the warhead’s pre-formed fragments. The fragmentation law of the warhead was experimentally and numerically studied under different initiation conditions. Combined with the azimuth detection fuze, the warhead detonation strategy under different azimuths is obtained. A target vulnerability equivalent model is used to simulate, the effect of the matching relationship between the fuze delay and miss distance on the damage effect. The simulation and experiment results show that with eccentric 45° two-line, 90° three-line, and 135° four-line detonation, the directional fragment velocity gains are 8.88 %, 10.99 %, and 10.85 %, respectively, while the resulting directional gain areas are 135°, 90°, and 45°, respectively. The target occupation azimuths coincides with the fragment directional gain areas, causing the best damage to the target. For optimal damage effect, the miss distance should be less than 10 m, and the fuze delay should not exceed 3 ms. Conversely, a fuze delay exceeding 5 ms results in inferior, damage effect and may not cause damage to the target effectively.
