综述了战斗部轴向速度梯度的试验研究、工程估算方法,以及由于轴向速度梯度存在而得到的静爆与弹目交汇条件下穿靶试验的对比仿真结果,指出在聚焦式战斗部设计中,应避免破片之间的速度差过大,影响弹目交汇条件下破片在目标上的聚焦性能,最后给出了实现等爆轰场强的几种方式。 The experimental research on the axial velocity gradient of the warhead, the engineering estimation method, and the comparative simulation results of the static projectile and the projectile with the projectile crossing due to the axial velocity gradient are summarized. It is pointed out that in the design of the focused warhead , The speed difference between the fragments should be avoided to be too large, which will affect the focusing performance of the fragments on the target under the condition that the projectile converges. Finally, several ways to realize the detonation field strength are given.
