摘要
为准确掌握非致命空爆弹的外弹道特性,通过建立弹丸质心运动的数学模型,运用MATLAB软件对外弹道模型进行仿真计算,在确定初速和射角的情况下,根据是否考虑空气阻力,分别得到弹丸飞行至距地面5m时所需的时间,并对时间差值进行分析.仿真结果表明:在一般情况下,空气阻力对非致命空爆弹的外弹道轨迹有一定的影响,速度越大,阻力越大,外弹道轨迹偏离的程度就越明显.这一结果为非致命空爆弹的优化设计提供了合理的依据.
In order to grasp the external trajectory characteristics of non-lethal air-burst grenade accurately,a centroid movement mathematical model of the projectile is established,and by using MATLAB software to simulate and calculate the external trajectory model,and with the initial velocity and the angle of fire determined,according to whether the influence of the air resistance is considered,the times of grenades flying to 5meters above the ground are obtained respectively,and the time differences are analyzed.The simulation results show that air resistance has certain effect on the external trajectory of non-lethal air-burst grenade in most cases and the faster the grenade flies,the greater air resistance is,the more obvious the degree of deviation of the external trajectory will be.The findings offer reasonable basis for the optimization design of non-lethal air-burst grenade.
