弹丸近炸破片密度分布与运动规律研究
Study on Density Distribution and Motion Law of Projectile Debris
摘要
Abstract
It is difficult,in general,to obtain the coordinates of the burst point of projectile in the shooting range and capture the debris movement law after explosion.In order to solve these problems,this paper,based on the analysis of projectile debris movement law,studied the debris density distribution of the single and multiple projectiles in the plane of intersection after the explosion,and proposed the velocity decay law of projectile fragments based on the expounding of the projectile fragments motion.Then,the initial velocity attenuation curve was obtained by calculation and analysis.The simulation results show that when the initial velocity and the scattering distance of the fragments are the same,the velocity after the decay of the fragments is proportional to the mass of the individual fragments.And the greater the quality of the fragments is,the faster the velocity becomes.It is of great significance for analyzing the relevant movement law of the projectile fragments after explosion,and improving the structure design of projectile.关键词
