摘要:
针对靶场测试中弹丸炸点空间坐标难以获得及炸后碎片运动规律难以捕获的问题,分析了近炸弹丸炸后的碎片散布规律,研究了单发和多发弹丸炸后在弹目交汇平面上形成的碎片密度分布,阐述了弹丸炸后形成的破片运动,给出弹丸炸后形成的破片的速度衰减规律。通过计算与分析,将破片初速进行划分,给出破片速度衰减曲线,仿真结果显示当破片的初速和飞散距离都相同时,破片衰减之后的速度(存速)与单枚破片质量存在正比关系,破片质量越大则存速越大。
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.
