变速枪内弹道模拟仿真

Simulation of Variable Velocity Gun Interior Ballistics

反恐防暴非致命武器需要根据不同射击距离调整弹丸的发射速度,为分析这种变化在武器射击过程中的内弹道过程,运用MATLAB软件对某变速枪的气室容积变化如何影响膛内压力和弹丸速度进行模拟仿真。结果表明:不同的气室容积,膛内压力变化不同,弹丸初速也不同;可通过调整气室容积改变弹丸的初始速度。

Anti-terrorism and anti-riot non lethal weapon needs to adjust projectile firing speed according to the different shooting distance to realize terminal effects as consistent as possible, thus the transmission speed is varied. For an analysis of the change in the firing process of the interior ballistic process,by using MATLAB the impact of gas chamber vol- ume changing on the internal pressure and the velocity of the projectile is simulated. Analy- sis results show that： as the gas chamber volume continues to increase, maximum value of the pressure decreases, which means that it has certain reference significance for the interior ballistic of the variable velocity gun.
