摘要
衰减系数直接关系到破片能否对目标进行有效的毁伤,而形状系数对衰减系数有很大的影响。当圆柱形破片在空中飞散时,迎风面积随机变化,导致圆柱形破片的形状系数不再是单一的值,而是一个范围,因此必须对已有的圆柱形破片的形状系数进行修正,才能更准确的预测圆柱形破片在空中的速度衰减。文中在试验的基础上,详细的对不同尺寸不同材质的圆柱形破片的形状系数进行了分析,并进行了修正,通过计算值与试验测得的数据进行比较,说明该修正系数可以应用于工程实践中。
Whether a target is efficiently damaged by fragments is directly connected with a decline modulus,and the decline modulus is greatly influenced by a figure modulus.When a cylindrical fragment is in the air,it is discovered that windward area is stochastic,so the figure modulus of the cylindrical fragment is not single but variable in a range.Therefore.in order to forecast the velocity decline of the cylindrical fragment in the air,it is important to modify the old figure modulus of the cylindrical fragment.In this paper,according to an experiment,the figure modulus of the cylindrical fragment whose dimensions and materials are different is analyzed in detail and amended, and by the comparison between the computed results and the experimental results,it is concluded that the modified modulus is applied in engineering.
