| 摘 要： | 作为一种简便、经济的加载方式,火炮试验已被广泛用于高速撞击研究,在导弹战斗部和弹头的终点效应研究中发挥了重要作用。试验中,弹丸的着靶姿态对试验精度具有重要影响。因此针对火炮试验弹丸的短距飞行等特点,对其质心的运动特征进行了分析,计算了典型火炮试验状态下弹丸着靶前的攻角。结果表明:在小于12 m的飞行距离内,不论其稳定性如何,其姿态均不会因俯仰力矩作用而明显改变,从而得出了弹丸姿态主要取决于初始扰动,而与其稳定性关系不大的结论。进一步分析了初始扰动形成的原因及其影响因素,探讨了改善弹丸着靶姿态的对策。由实例分析验证了本文结论。

| Abstract: | As a convenient and economic loading mode,the gun tests are widely used in high-speed impact tests and play an important role in terminal effects research of missile warheads and projectile.In the tests,the accuracy can be significantly influenced by the projectile's attitude.The attitude control method for short-distance flying projectiles was discussed,the movement characteristics of its barycenter was analyzed,and its attack angle before impacting target was calculated also.The results show that,in the f... |
