摘要
通过靶场试验的方法得到弹药在不同飞行速度下爆炸的弹药起爆位置、破片空间分布数据;根据破片空间分布和弹药起爆位置计算出破片杀伤带的飞散方向角;分析发现:用矢量叠加法描述动静爆破片群飞散特性的关系与试验结果有一定误差,两者的差别随着弹药飞行速度的增大更加明显;运用冲击波相关理论分析得出弹药动静爆破片飞散特性的不同之处,提出一种计算动爆弹药破片群飞散方向角的修正矢量叠加法,为评估动爆弹药威力工作奠定一定的基础。
The detonation position,velocity and fragment dispersion data of a certain type of ammunition exploded at different flying velocity were obtained by shooting range test.According to the fragment dispersion and the detonation position,the scattering direction angle of fragment kill strip was calculated.It is found that the fragment dispersion characteristics of dynamic blasting are not the vector superposition of the fragment dispersion characteristics of static blasting and the flying velocity of ammunition,and the difference between them is more obvious with the increase of the flying velocity.Based on the theory of shock wave correlation,the difference of the dynamic and static fragments dispersion characteristics of ammunition is obtained.A modified vector superposition method for calculating the scattering direction angle of fragment kill strip of explosive ordnance is also presented,and it lays a solid foundation for evaluating the power of explosive ordnance.
