摘　　要：国际主流防暴枪采用滑膛枪管发射非致命弹丸,存在射击精度差弹丸飞行稳定性不高等突出问题,极易造成对目标的不可逆杀伤甚至死亡。通过简化一般情况下的旋转体运动学方程,得到球形非致命弹丸在自旋情况下的短周期运动学方程组,并用SIMULINK建模仿真。仿真结果表明,弹丸飞行稳定性与飞行速度无关与自旋速度有关,且自旋速度越快则稳定性越好射击精度越高但存在收敛的极限。仿真结果可以为新型线膛式防暴枪的研制提供一定依据和参考。International mainstream anti-riot guns use a musket barrel to fire non-lethal projectiles,which has a prominent problem of poor shooting accuracy and unstable flight of projectiles,easily causing irreversible damage and even death to the target.In this paper,by simplifying the kinematics equation of the rotating body in general,the short-period kinematics equations of the spherical non-lethal projectile under the condition of spin are obtained,and the modeling and simulation are carried out by SIMULINK.The simulation results show that the flight stability of the pro⁃jectile has nothing to do with the flight speed and is related to the spin speed,and the faster the spin speed,the bet⁃ter the stability,and the higher the shooting accuracy,but there is a convergence limit.The simulation results can provide a certain basis and reference for the development of the new ribbed anti-riot gun.
