为提高战斗部在目标方向上的破片密度，设计了一种新型滑块式定向战斗部。建立了该滑块式定向战斗部与普通偏心起爆定向战斗部的有限元模型，运用数值模拟和静爆试验相结合的方法研究了该定向战斗部的破片数目和速度增益。结果表明，该滑块式定向战斗部与相同质量和装药量的普通偏心起爆定向战斗部相比，在定向方位90°角度范围内破片数目增益38.8%，初速减小3%。

A sliders aimed-warhead was put forward based on the idea of controlling fragments dis-tribution in the warhead.The finite element models of the sliders aimed-warhead and the ordinary eccentric detonation aimed-warhead were built.The static blasting experiment was combined with numerical simulation method,and the fragment number and the circumferential velocity of the aimed warhead in the range of orientation direction 90°were studied.The results show that the fragment number of sliders aimed-warhead can gain 38.8%,and fragments velocity decreases 3%compared with the ordinary eccentric detonation aimed-warhead of the same quality warhead, charge and single fragment quality.
