摘要:

为了为某型动能防暴发射器选择最优橡胶弹丸,建立了橡胶圆球弹外弹道模型,从国内外典型橡胶圆球弹的大小、空气阻力对弹道的影响和终点效应三方面分析了对橡胶圆球弹选择的影响,利用MATLAB仿真软件计算了8 mm、10 mm、15 mm3种直径不同质量条件下的空气阻力对弹道的影响、最大射程、终点速度、飞行时间、动能和比动能；重点分析比动能和K值对弹道特性及终点效应的影响,通过分析和比较,得出了直径为10 mm,质量为2 g的橡胶圆球弹最适合作为某型动能防暴发射器的战斗弹丸；通过分析直径10 mm,质量2 g的橡胶圆球弹不同发射角度情况下的弹道特性和终点效应,结果表明,该橡胶圆球弹存速能力强,发射距离远,安全性高,为某型动能防暴发射器的弹丸制造提供了理论支撑。

Abstract:

In order to select the optimal rubber bullets for a certain type of anti-riot disperser of kinetic energy , trajectory model of rubber ball is established ; three factors affecting the choice of rubber ball projectile which are the influence of air resistance on trajectory, the size of domestic and foreign typical rubber bullets and terminal effect are analyzed. Using MATLAB simulation software to analyze the influence of air resistance on trajectory , the farthest range, flight time, kinetic energy and specific kinetic energy of 8 mm, 10 mm, 15 mm three kinds of different diameter and quality of rubber ball , the effects of specific kinetic energy and K value on ballistic characteristics and terminal effect are analyzed importantly; By analyzing and comparing, the diameter of 10 mm and the mass of 2 grams is the most suitable for a certain type of anti-riot disperser .Through analyzing the ballistic characteristics and end effect on the rubber bullets which diameter is 10 mm and the mass is 2 grams, under different emission angle, the results show that it has the ability to keep speed and have the characteristic of remote operational distance, high safety, providing theoretical support for the manufacture of a certain type of anti-riot disperser of kinetic energy.
