前向战斗部形成尽量均匀的破片场对毁伤目标是必要的,因此需要对其破片散布均匀性进行定量分析。通过静爆试验得到了破片分布数据。根据破片散布特点,提出了评价战斗部径向均匀性的方法并进行了定量分析。破片区沿径向可分为中心均匀区、过渡区、稀疏区和外缘无效破片区4个部分。过渡区和稀疏区破片约占总数的45%,其分布密度随半径下降很快,必须改进战斗部结构使其向中间收敛。破片周向散布均匀性良好,均匀性指数为0.92。

It is necessary to get a uniform fragments field for the forward-firing warhead, for this reason, quantitative analysis on fragments dispersion uniformity is important. Fragments dispersion data was obtained through forward-firing warhead static explosion experiment. Considering the dispersion characteristics, the method evaluating fragments radial dispersion uniformity was proposed and quantitative analysis was made. The fragments dispersion area can be divided into four parts along the radial direction; they are central denseness zone, transition zone, sparseness zone and marginal ineffectiveness zone. The fragments in the transition zone and sparseness zone take about 45% of the totality. The fragments field density in those two zones decreases rapidly, so the warhead structure should be improved to make the marginal fragments close to the warhead axial line relatively. The circumferential dispersion uniformity of the fragments is well, and the uniformity index number is 0.92.
