摘要

针对当前各爆炸仿真软件解决壳体破碎问题的不足,将经典壳体破碎理论和数值仿真方法充分结合,建立了一种新的仿真方法,以此来计算弹丸破碎时壳体半径与破片大小和数目的关系,从而为弹丸的威力设计提供理论帮助。通过编制的Matlab程序,并进行大量的数值实验,得出了圆环不同半径与破片尺寸和数目的关系。经计算表明,这种方法可以减少实验量,且计算结果比较可靠。

Abstract

According to shortage of explosion simulation software solving shell breaking, both classical shell breaking theory and method of numerical simulation were combined, and a new simulation method was built. Matlab program was compiled, vast numerical experimentation was done. It gained the relationship between different radius of annulus with size and number of fragment. This method could reduce experimentaion number, and offer informantion to design projectile.

Key words： projectile shell; breaking; explosion; Matlab
